What Is Abrasive Machining?

This process can supplant conventional large-chip machJasa Machining ining operations like milling, planing, broaching, and turning

There’s precision grinding and then there’s abrasive machining. So, what is the difference?

Insofar as grinding processes go, there couldn’t be two processes that look so similar yet are so juxtaposed. The mere mention of the word “grinding,” to some manufacturing professionals, conjures up nightmare scenarios of processes that take forever to remove hardly any material, at a stage where the part is of high value, and any mishap will be costly. Some have been known to break out in hives.

Abrasive machining is not precision grinding. The objective is neither super precision nor high-luster surface Jasa Machining Medan finishes. Abrasive machining first and foremost generates high stock removal. Abrasive machining is not considered to be a precision grinding process, but that’s not to say it isn’t precise. 

Abrasive machining can take the place of “large-chip” machining processes like milling, planing, broaching, and turning. Compare the surface finish and the precision achieved with the large-chip processes to the surface finish and precision achieved by abrasive machining, and there is no comparison—abrasive machining is far superior. Not only is abrasive machining more precise than large-chip processes (size tolerances within 0.001″ or 0.025 mm and form tolerances to within 0.0005″ or 0.0127 mm), it also produces a significantly better surface finish. An added bonus is that there is little to no burr generated. Abrasive machining has one other major feature—it’s the means by which difficult-to-machine materials become machinable, be they metals or nonmetals.

Abrasive machining was rooted in the aerospace industry in the late 1950’s when milling and broaching the dovetail and fir-tree root forms on the ends of compressor and turbine blades was considered difficult, if not impossible. It was during the late ’50s that Edmund Lang (founder of ELB in Babenhausen, Germany) and his son Gerhard were experimenting with electrochemical grinding. One of their experiments appeared to go wrong when the grinding wheel was fed slowly through the workpiece with a large depth of cut, but without any electrical current. To their surprise and astonishment, the wheel walked right through the workpiece as though it was a milling cutter—Creep-Feed Grinding (CFG) was born.

Creep-feed grinding has shown how it can remove very difficult-to-machine materials quite easily and economically, with minimal burrs and with accurate form-holding capability. CFG was the first of the abrasive machining processes, though, as we might see later, abrasive cutoff may be considered abrasive machining too. Then, away from the aerospace industry, CFG began to spill over into other applications. A workpiece might have previously been rough-milled in its soft state, heat-treated, and hardened prior to a finish-grinding operation. CFG allows such parts to be through-hardened and creep-feed ground from solid. In those early days of CFG, the machining cycle was felt to be fast for machining the impossible to machine. The overall cost was reasonable, and the surface integrity was far superior to that of milling or broaching. Oftentimes, today, the overall cost of milling versus creep-feed grinding can be a wash, but it’s the surface finish and the virtually burr-free nature of the process that nets a major saving in post-machining operations.

While CFG is much like milling, it uses a grinding wheel in place of a milling cutter. Unlike conventional surface grinding, CFG demands a machine tool of high stiffness and high power. The early creep-feed grinders used conventional vitrified bonded abrasives with aluminum oxide or silicon carbide grain, in a very open structure and having quite fragile bonds. Back then, producing such a tool was a challenge for the grinding-wheel manufacturers. The process also used crush dressers or diamond rolls to intermittently dress full-wheel-width forms onto the grinding wheels in very short dressing times. The grinding wheel would make one roughing pass through the material. It would then be dressed to sharpen the wheel surface, as well as refurbish the form, and a final, lighter cut was made to finish size. The cycle would then repeat.

The throughput and productivity of CFG needed to improve, as well as the ability to avoid surface cracks and workpiece burn. In the late 1970’s, Continuous-Dress Creep-Feed grinding (CDCF) came onto the scene. Instead of dressing between parts or passes, the grinding wheel is constantly dressed while it’s machining. Not only is the grinding wheel held continuously in a constant state of maximum sharpness, but the form is accurately maintained. The level of sharpness of the grinding wheel is such that stock removal rate could increase by a factor of 20 or more over conventional grinding, even in the most difficult-to-machine nickel and cobalt-based superalloys. What took minutes to achieve by the old CFG process takes seconds with CDCF. This new process revolutionized turbine blade manufacture, and spurred the development of automated grinding cells that took a rough cast turbine blade to a fully inspected finished part—without the workpiece being touched by a human hand.

Jasa Machining Medan Abrasives research was on the march too. Superabrasives (diamond and CBN) were making their mark, mostly in resin bonds and more for conventional precision grinding applications. Then vitrified superabrasive wheels appeared. Obviously, they were not candidates for any continuous dressing, due to the high cost of the abrasive, but the life of a CBN wheel was significantly greater than that of an aluminum oxide or silicon carbide wheel. High-production systems began to use intermittently dressed vitrified superabrasive wheels in a creep-feed mode. It was, however, necessary for the application to be high production, or at least have a common form, because the cost of frequently redressing a different form on a vitrified CBN wheel, versus an aluminum oxide wheel, is prohibitive.

An “intermediate” abrasive that appeared in the late 1970’s is ceramic aluminum oxide. The 3M Co. called its product Cubitron, and Norton chose the name SG (for Sol-Gel or Seeded Gel). An aggressive shape abrasive, ceramic aluminum oxide has a longer life than fused aluminum oxide. The ceramic abrasive does, however, require a high force on the individual grains to initiate grain fracture and self-sharpening. CFG, on the other hand, creates very low forces on the individual grains. Initially, the ceramic abrasive was not well suited to CFG, so hybrid wheels that combined fused and ceramic aluminum oxide became popular. Later, ceramic technology allowed the production of high-aspect-ratio grains that were better suited to CFG, especially when machining the softer, more gummy materials, such as stainless steels and superalloys. The high aspect ratio can go anywhere from 4:1 to 8:1, giving the grain a directional friability. Depending on the complexity of the form, a ceramic aluminum oxide wheel can compete with CDCF.

Higher wheel speeds will typically produce faster cut times and longer wheel life. It has long been understood that aluminum oxide does not perform well at very high speed. In fact, speeds over 6000 fpm (30 m/sec) tend to cause accelerated attritious wear of the abrasive grain. In a plastic bond (not a resin bond, which employs a thermosetting plastic, but a thermoplastic plastic), however, aluminum oxide has performed well at higher wheel speeds.

At high speed, CFG is typically performed using plated superabrasive grinding wheels (12,000–24,000 fpm or 60–120 m/sec). This is called HEDG—High Efficiency Deep Grinding. Today, wheels may also be made with vitrified superabrasive segments bonded to the periphery of a metal core. To move grinding wheel speeds into the ultra-high speed grinding (UHSG) regime (above 40,000 fpm or 200 m/sec), the wheel core must be made of metal, and the abrasive is likely to be plated. Such wheels can run at nearsonic speeds (66,000 fpm or 335 m/sec) without the fear of bursting. The paling aman issue here is more of a “wheel off” situation. The likelihood of a metal-core wheel bursting is remote. But mounting a wheel to a spindle, on a taper, gives rise to weak design areas close to the bore of the wheel, where the tertekan is highest. Ultra-high-speed machines need to be designed with a “wheel-off” condition in mind. To date, UHSG has only been done in the lab. Few production systems today are running in excess of 30,000 fpm (150 m/sec).

As far as safety is concerned, human life is unlikely to be in danger during a UHSG operation, because the stock removal rate is so fast that loading and unloading of parts, as well as wheel changing, will be done automatically. Unlike the manual machines of yesteryear, there will be no personnel nearby to be injured.

What Is Machining? Intro To Machine Shop Processes & Tools

Home/Guides/What is Machining? Intro To Machine Shop Processes & Tools

Machining is a technical and detail-oriented process in Jasa Machining which material is cut into a final shape and size to create parts, tools, and instruments. Machining is typically used to shape metals, though it can also be used on a variety of other raw materials. Machine shops utilize equipment and tools like mills, lathes, and drill presses to cut material and 3D printers to add material.What is machining?

Machining is the process used to remove material, typically metal, to create parts for machines, tools, transportation, and more. Machine shops and machinists use equipment like lathes, mills, and drill presses to turn material into useful tools using precise cuts.

What do machine shops do?

Machine shops use equipment and machines to create tools and parts. These parts need to be strategically cut using a high level of accuracy to fit their specific function and fit the machine they will be used in. Machinists remove material from objects that are made of metal, though machining techniques can also be used on wood, ceramic, and plastic materials. Machining is used on engines, bicycles, appliances, kinetic or mechanical projects, and much more.What materials can be machined?

Machining is most commonly used to manufacture metal objects, parts, and tools. Metals that can be machined are stainless steel, aluminum, brass, titanium, and copper. Stainless steel is commonly used for precision machining, offering the advantages of strength and resistance to corrosion. Aluminum is lightweight, easy to work with, and inexpensive. Brass is another economical material used for machining, but should not be used in semiconductor products because of the zinc and tin in the material. Titanium is strong, lightweight, and resistant to corroding, however, it is more expensive than other materials and difficult to work with. Copper is a versatile and strong metal and works well as an electrical conductor. Plastics are also used in machining as they are inexpensive and non-conductive. They are commonly used in medical, electrical, and scientific industries.

Machining processes explained

Machining is the process of removing material on a workpiece in order to create a precise object or Jasa Machining Medan part. The following are the primary processes used to cut and subtract material in a machine shop by a machinist.Turning

Turning is a process that rotates the workpiece as the primary method of moving metal against the cutting tool. Lathes are the principal machine tool used in turning.Milling

Milling uses a rotating cutting tool to bring cutting edges to bear against the workpiece. This is the most versatile tool and technique used in a machine shop.Drilling

Drilling creates a new hole or refines an existing hole using a rotating cutter. Drilling is most commonly done using drill presses, but sometimes drilling tools will be attached to compatible lathes or mills to create holes.Boring

Boring is one of the most widely used techniques in machining, as it is one of the most reliable ways to finish and enlarge pre-existing holes. This technique provides accuracy and is easily replicated on a workpiece.Reaming

Reaming is a process that uses a rotary cutting tool to smooth an existing hole in a workpiece. This is a cutting process that removes material, and its primary purpose is to even out the walls of a hole.

There are two main techniques when it comes to machining operations: subtractive and additive manufacturing. These techniques are used by a machinist to either take away or add material to a part.Subtractive

Machining is a prototyping and manufacturing process that creates the desired shape by removing unwanted material from a larger piece of material. Since a part is built by taking away material, this process is also known as subtractive manufacturing.Additive

Additive machining, also known as 3D printing, is a newer approach to production that enables the construction of a three-dimensional object from a digital model. It allows the machinist to create lightweight and strong parts.

Common machine shop tools

There are many types of machining tools, and they may be used alone or in conjunction with other tools at various steps of the manufacturing process. Some tools in a machine shop have very specific purposes, while others are more versatile and can be used for many different uses.Cutting tools

Cutting tools in a machine shop include devices like saws and shears. They are used to cut material with specific and predetermined dimensions, such as sheet metal.Boring tools

Boring tools are used to enlarge or re-shape an established hole. A machine shop may use a jig borer to accurately locate the precise center of a hole and a horizontal boring machine to perform the cut. Modern machining also uses CNC machines to ensure repeatability throughout a workpiece.Drilling tools

Drilling tools are devices that rotate to create round holes on a workpiece by removing material. A machine shop may have a designated drill press for hole making or specific tools that can be attached to compatible machineries such as a lathe or CNC machine.Turning tools

Turning tools rotate a workpiece while a cutting tool removes material, shaping it to the desired form. Horizontal lathes are the most common type of turning machine used in a machine shop.Grinding tools

Grinding tools use a rotating wheel to make light cuts, sharpen tools, or create a finish on a machined workpiece. Pedestal grinders are commonly used in machining to sharpen cutting functions on turning and milling machines. Grinding tools can also deburr and remove any surface imperfections on a workpiece, creating a smooth finish.Milling tools

A mill uses a rotating cutting surface with several blades to create holes or cut designs out of the material. The milling machine is used to mill flat and irregular surfaces, and also to drill, bore, cut, and create slots on a workpiece. The Bridgeport Mill is a merk that became ubiquitous in machine shops around the world.

It is important to first learn machining from an experienced instructor in an established machine shop. At The Crucible, you can learn the secrets of machining to drive sharp cutting tools using lathes, milling machines, and drill presses—and make precise, accurate cuts. Our machine shop offers introductory classes for machinists that are just starting out, and open Jasa Machining Medan lab time is available for students to perfect their machining skills and for experienced workers to work on personal projects.Machining FAQsWhat is machining used for?

Machining is used to create precise parts and tools for engines, bicycles, appliances, kinetic or mechanical projects, scientific and medical industries, and much more.What is hybrid machining?

Hybrid machining combines both additive and subtractive machining processes. This process enables the application of different metals on the same part. This can cut down on material costs and time spent on a single project. The downside of hybrid machining is a high set up cost and substantial investment to install new technology in the machine shop.What does a machinist do?

Machinists use tools, such as lathes, milling machines, and grinders, to produce parts, instruments, and tools. Machinists work in a machine shop using blueprints, sketches, or computer-aided design (CAD) to create precise objects to be used in machines and mechanical objects.Is it hard to become a machinist?

It is relatively easy to become a machinist as entry level positions are widely available. Many machinists enter the field after high school and complete a 1-dua year apprenticeship. Machinist’s skills are highly valuable to employers, so there is a high demand for their experience at various manufacturing companies.Continue Exploring Guides In Machine

Introduction To Cnc Machining

Learn the basic principles and mendasar mechanics of CNC machining and how these relJasa Machining Jasa Machining Medan ate to its key benefits & limitations.

Written by Alkaios Bournias VarotsisHow does CNC machining work?

There are two main types of CNC machining systems: milling and turning. Each is better suited for manufacturing different geometries, due to its unique characteristics.

Let’s break down how parts are manufactured using these two machine setups…How does CNC milling work?Schematic of a typical CNC milling machine

CNC milling is the most popular CNC machine architecture. In fact, the term CNC milling is often synonymous with the term CNC machining.

In CNC milling, the part is mounted onto the bed and material is removed using rotational cutting tools. Here is an overview of the basic CNC milling process:First, the CAD model is converted into a series of commands that can be interpreted by the CNC machine (G-code). This is usually done on the machine by its operator, using the provided technical drawings.A block of material (called the blank or the workpiece) is then cut to size and it is placed on the built platform, using either a vice or by directly mounting it onto the bed. Precise positioning and alignment is key for manufacturing accurate parts and special metrology tools (touch probes) are often used for this purpose.Next, material is removed from the block using specialized cutting tools that rotate at very high speeds (thousands of RPM). Several passes are often required to create the designed part. First, an approximate geometry is given to the block, by removing material quickly at a lower accuracy. Then one or more finishing passes are used to produce the final part.If the contoh has features that cannot be reached by the cutting tool in a single setup (for example, if it has a slot on it back side), then the part needs to be flipped and the above steps are repeated.A typical CNC milled part, manufactured by removing material from a rectangular blank

After machining, the part needs to be deburred. Deburring is the manual process of removing the small defects left on sharp edges due to material deformation during machining (for example, the defects created as a drill exists the far side of a through hole). Next, if tolerances were specified in the technical drawing, the critical dimensions are inspected. The part is then ready to use or post-process.

Most CNC milling systems have 3 linear degrees of freedom: the X, Y and Z axis. More advanced systems with lima degrees of freedom also allow the rotation of the bed and/or the tool head (A and B axis). 5-axis CNC systems are capable of producing parts with high geometric complexity and may eliminate the need for multiple machine setups.How does CNC turning work?Schematic of a typical CNC turning machine

In CNC turning, the part is mounted on a rotating chuck and material is removed using stationary cutting tools. This way parts with symmetry along their center axis can be manufactured. Turned parts are typically produced faster (and at a lower cost) than milled parts.

Here is a summary of the steps followed to manufacture a part with CNC turning:The G-code is first generated from the CAD model and a cylinder of stock material (blank) with suitable diameter is loaded in the CNC machine.The part starts rotating at high speed and a stationary cutting tool traces its profile, progressively removing material until the designed geometry is created. Holes along the center axis can be also manufactured, using center drills and internal cutting tools.If the part needs to be flipped or moved, then the process is repeated. Otherwise, the part is cut from the stock and it is ready for use or further post-processing.A typical CNC turned part, manufactured by removing material from a cylindrical blank

Typically, CNC turning systems (also known as lathes) are used to create parts with cylindrical profiles. Non-cylindrical parts can be manufactured using modern multi-axis CNC turning centers, which are also equipped with CNC milling tools. These systems combine the high productivity of CNC turning with the capabilities of CNC milling and can manufacture a very large range of geometries with (looser) rotational symmetry, such as camshafts and radial compressor impellers.

Since the lines between milling and turning systems are blurry, the rest of the article focuses mainly on CNC milling, as it is a more common manufacturing process.Machine Parameters

Most machining parameters are determined by the machine operator during the generation of the G-code and are usually of little interest to the designer. The machine parameters of interest are the build size and the accuracy of the CNC machine:

CNC machines have a large build area. CNC milling systems can machine parts with dimensions of up to 2000 x 800 x 100 mm (78’’ x 32’’ x 40’’) and CNC turning systems can manufacture parts with diameter of up to Ø 500 mm (Ø 20’’).

With CNC machining, parts with high accuracy and tight tolerances can be manufactured. If no tolerance is specified, then parts will be machined with a typical accuracy of ± 0.125 mm (.005’’). Tight tolerances down to less than half the diameter of an average human hair (± 0.025 mm or .001’’) can be achieved with CNC.CNC Cutting Tools

To create different geometries, CNC machines use different cutting tools. Here are some of the most commonly used milling tools in CNC:A selection of the most common CNC cutting tools (not in scale)

The flat head, bull head and ball head end mill tools are used to machine slots, grooves, cavities and other Jasa Machining Medan vertical walls. Their different geometry allows the machining of features with different details. Ball head tools are also commonly used in lima-axis CNC machining to manufacture surfaces with curvature and freeform geometries.

Drills are a common and fast way to create holes. You can find tables with the standard drill sizes here. For hole with non-standard diameter, a plunging flat head end mill tool (following a helical path) can used.

The diameter of the shaft of slot cutters is smaller than the diameter of their cutting edge, allowing these milling tools to cut T-slots and other undercuts by removing material from the sides of vertical wall.

Taps are used to manufacture threaded holes. To create a thread, precise control of the rotational and linear speed of the tap is needed. Manual tapping is also still commonly used in some machine shops.

Face milling cutters are used to remove materials from large flat surfaces. They have a larger diameter than end mill tools, so they require fewer passes to machine large areas, reducing the total machining time and producing flat surfaces. A face milling step is often employed early in the machining cycle to prepare the dimensions of the block.

An equally large range of cutting tools are also used in CNC turning, covering all machining needs, such as face cutting, threading and groove cutting.

Here is a video of a face milling cutter in action:Geometric Complexity & Design Restrictions

CNC offers great design freedom, but not every geometry can be CNC machined. Unlike 3D printing, part complexity increases the cost, as more manufacturing steps are required.

5-axis CNC systems allow the cutting tool to access areas that are impossible to reach with 3-axis systems

The main restrictions in CNC have to do with the geometry of the cutting tool. For example, the internal edges of a slot will always be rounded, as they are machined using a tool with a cylindrical profile.

Tool access is another major restriction in CNC: material cannot be removed unless the tool can reach that area. Most CNC machines are tiga-axis systems, so any feature must be designed so that it can be accessed directly from above. lima-axis CNC systems offer greater flexibility, allowing the creation of more intricate parts, as the angle between the part and the tool can be adjusted to gain access to difficult to reach areas.

Parts with thin walls or other fine features are difficult to CNC machine. Thin walls are prone to vibrations and are in danger of breaking due to the cutting forces. The minimum recommended wall thickness is 0.8 mm for metals and 1.5 mm for plastics.

An article with more design guidelines specifically for CNC machining can be found here.Benefits & Limitations of CNC machining

The key advantages and disadvantages of the technology are summarised below:

CNC machining offers excellent accuracy and repeatability, and can produce parts with very tight tolerances, making it ideal for high-end applications

CNC materials have excellent and fully-isotropic physical properties and are suitable for most engineering applications.

Parts and Components Made by CNC Machining

Industrial Uses for CNC Machining

And much more…

Scroll down to chapter one to begin.

Chapter One – What is CNC Machining?

CNC machining is an electromechanical process that manipulates tools around three to five axes, with high precision and accuracy, cutting away excess material to produce parts and components. The initial designs to be machined by CNC machining are created in CAD, which is then translated into CNC codes to provide programmed instructions to the tools in a CNC machine.

CNC machining produces cutting edge quality on turned components using a wide variety of applications that require vertical and horizontal machining.

The multitasking ability of CNC machines allows for the completion of a component or part in a single operation, with ease and efficiency. The types of applications performed by CNC machines include bushings, collars, fasteners, fittings, Jasa Machining inserts, machined components, machined washers, pins, nuts, spacers, spindles, standoffs, drive shafts, and splined shafts to name a few.

Chapter Two – The CNC Machining Process

CNC or Computer Numerical Control machining is a logical and rational process that is planned and designed for the efficient production of parts. The computer controlled machines perform a variety of tasks that have been programmed into the equipment, which begins with creating a two or three dimensional rendering on a computer.

Once the design file is loaded and coded, the machine performs each operation according to the design parameters.

The CNC Machining Process

The difference between CNC machining and other manufacturing processes is that it is a subtractive process that removes layers of material to achieve a particular shape.

Computer Programming

The key to the success of CNC manufacturing is the initial programming. The aplikasi must be coded with the proper instructions keeping the machine within its limitations. The processes for CNC equipment are derived from the person who creates its instructions. Care is taken in the development of the programmed instructions to avoid errors and loss of production time.

Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM)

CAD-CAM is a descriptive term for the perangkat lunak used for designing and machining parts and components using a CNC machine. CAD is perangkat lunak used to design, draw, create, and shape parts through the use of geometric shapes and constructs. CAM, on the other hand, takes the information from CAD and translates it into machine language, which is referred to as G-Code.

Before the CAD designed contoh can be changed into machine language, the CAM software determines the cutting paths for the tools for the removal of the excess material from the workpiece. CAD and CAM work together to provide the CNC machine with the proper and accurate instructions to perform the necessary cutting operations.

CNC Machine Setup

Before the CAD-CAM acara can be downloaded into the machine, it has to be set up with the proper cutting tools. There are two methods for completing tool changing. The first method is by pulling tools from the tool cart and placing them in the machine.

The second method is an ATC or automatic tool changer, which has tools stored on a drum or chain. When programmed with the required tools, the ATC removes the old tool and inserts the new one. The purpose of an ATC is to save time and increase efficiency.

An important part of CNC machine setup is the establishment of the gage point, which is how long the tip of the tool is from a point of reference. The proper setting of this part of the process ensures that the tool will cut to the appropriate depth.

One of the final steps in CNC machine setup is the testing of coolant or lubricant. Jasa Machining Medan Coolant is delivered by either air, mist, flood, or high pressure. An essential part of checking the coolant is determining the pressure at which it is delivered. The wrong pressure can lead to tool damage, while the wrong amount can damage the machine and equipment.

An unfortunate error made when setting up a CNC machine is failure to check the coolant, which can smell bad, have an insufficient amount, be of low concentration, or may not be appropriately filtered.

Work Holding

The work holding is a device that is used to secure, support, and mount the workpiece. Also referred to as a CNC fixture, it ensures conformity and interchangeability as well as smooth operation. Unlike a jig, the work holding device secures, supports, and stabilizes the workpiece.

Much like the tools used on a CNC machine, work holding fixtures come in several different types, which include turning, milling, drilling, boring, and grinding.

Loading the G-Codes

G-codes have been accepted as the universal language for CNC machining. Though there are standard G-codes for all CNC machines, manufacturers will change G-codes to make them specific to their machines. There is a G-code for every movement of the cutting tools in a CNC machine.

Though various forms of software will create G-codes from a CAD design, they can also be handwritten or conversational, which does not require the use of a CAD design. G-codes can be loaded into the CNC machine using a USB, directly from the CAM computer, or programmed directly into the machine.

Program Proofing

Program proofing is the final step before making the actual cuts. The purpose of proofing is to determine if the program is correct, and that the CNC machine setup is accurate to avoid problems with the g-code.

This process is used to examine if there are any errors in the g-code. Proofing can be accomplished by cutting air, where the machine runs through the cutting process without cutting the workpiece. Cutting air is time consuming and ties up the machine. Another method is g-code simulator, a computer acara that simulates the CNC process.

Machining the Part

Once all the preparations have been completed, it is time to insert the workpiece and do the cutting. The first workpiece must be watched carefully as it goes through the CNC process. It is the prototype for all of the parts to follow and will provide data and information regarding the success of the programming.


After the setup and testing processes are completed, the CNC machine is put into production. CNC machining allows producers to manufacture parts faster, more efficiently, and safely with every part being an exact duplicate of the original design.

Chapter Three – Types of CNC Machining

A major advantage of CNC machining is the wide array of cuts CNC machines can make. There is a limitless number of shapes, designs, configurations, and images that can be created by the CNC process. Its use enhances the quality of the final part and eliminates errors and flaws from the final product.

Types of CNC Machining

Though CNC machines can be programmed to perform a single function, one of the benefits of CNC machining is their ability to perform multiple operations in a single implementation of the tool. This quality allows producers to insert a single workpiece and have several cuts performed during one machine cycle.

Two types of cuts are male and female. Male cuts are around the outside edges of the workpiece to ensure that the workpiece has the proper dimensions. Female cuts are on the inside of the workpiece. Whether the cuts are male or female, the corners of the cuts are rounded.

Cleanout cuts are similar to female cuts but do not go all the way through the workpiece, while center or online cutting follows the center of the vector shape.

Play With Fire (the Rolling Stones Song) – Wikipedia, La Enciclopedia Libre

«PJasa Roll Plat medan lay with Fire» —en español: «Jugar con fuego»— es una canción de la banda inglesa de rock The Rolling Stones. Fue la cara B del tercer sencillo del grupo, The Last Time. Se Jasa Roll Plat medan atribuye a Jasa Roll Plat Nanker Phelge, seudónimo utilizado por la banda cuando las canciones fueron compuestas por todos los miembros.[1]​ Fue incluida en la versión estadounidense de su álbum de 1965 Out of Our Heads.Historia[editar]

La canción fue grabada en los estudios RCA ubicados en Hollywood, California, el 11 de enero de 1965. Contaron también con la asistencia del productor Phil Spector a la guitarra. Fue la cara B del sencillo The Last Time.Composición y grabación[editar]

“Play with Fire” se atribuye a Nanker Phelge, un seudónimo utilizado cuando las pistas fueron compuestas por toda la banda, a pesar de que el cantante Mick Jagger y el guitarrista Keith Richards son los únicos Stones que aparecen en la pista. La canción fue grabada tarde una noche en enero de 1965 mientras los Stones estaban en Los Ángeles grabando con Phil Spector en los estudios RCA. Richards realizó la apertura de la guitarra acústica de la canción mientras Jagger manejaba la voz y la pandereta (mejorada con una cámara de eco). Spector tocaba el bajo (en realidad una guitarra eléctrica afinada), y Jack Nitzsche proporcionó el clavecín distintivo de la canción.arreglo y tam-tams. Los Stones se fueron de gira por Australia al día siguiente.

La letra de la canción habla de la relación del cantante con una chica de la alta sociedad, menospreciando el estilo de vida de la misma manera que lo haría en 19th Nervous Breakdown, en una sensación más acelerada. El título se refiere al dicho “Si juegas con fuego, te quemarás”.

En una entrevista de 1995 con Jann Wenner para Rolling Stone, titulada “Jagger Remembers”, Jagger dijo: “Play with Fire” suena increíble, cuando lo escuché por última vez. Quiero decir, es un tipo de sonido muy directo y muy claramente hecho. Puedes escuchar todas las cosas vocales en él. Y estoy tocando las panderetas, la línea vocal. Sabes, es muy bonita “. Según Richie Unterberger, un amigo de los Stones escribió que también se grabó una versión inédita de la canción, titulada “Mess with Fire”, con una sensación mucho más optimista y orientada al alma. Sin larangan, la historia es considerada dudosa por Unterberger.Lanzamiento[editar]

“Play with Fire” fue al número 96 en la lista de los Estados Unidos. Fue incluida en la versión estadounidense de su álbum de 1965 Out of Our Heads. También apareció en la versión estadounidense del recopilatorio Big Hits (High Tide and Green Grass) (1966), Hot Rocks 1964-1971 (1971) y Singles Collection: The London Years (1989).En directo[editar]

La canción fue interpretada en concierto durante las giras de los Stones de 1965 y 1966. Fue recuperada 23 años después en el Steel Wheels/Urban Jungle Tour de 1989–90. Pasarían 27 años hasta que, de nuevo, se recuperó para el No Filter Tour de 2017.Personal[editar]

Bill Wyman On Playing With The Rolling Stones: ‘never Again’

The Rolling Stones‘ former bJasa Roll Plat medan assist Bill Wyman has said he will “never” play live with the bJasa Roll Plat medan and again.

Wyman, who played with the The Rolling Stones between 1962 until 1993, joined the band onstage for their 50th anniversary gigs at London’s O2 Arena last November (2012), but in April he said that he would not be interested in rejoining the group on a permanent basis because he has “better things to do”.

Now, in an interview with the Huffington Post, Wyman seemingly ruled out the possibility of performing with his former bandmates ever again. “The nice thing was that my kids saw me on stage with the Stones,” he said. “They’d asked me the December before, and I had to jam with them for three days. I was under the impression I was going to get really involved, but when it came to it, they only wanted me to do two songs, which was very disappointing.”

He then added: “I’ve always maintained that you can’t go back to things, and they can never be the same. it’s like a school reunion, or Tony Hancock’s Army reunion. If you try to go back and have a relationship with someone, it doesn’t work, and it’s the same musically. It doesn’t work. It was a one-off. Five minutes. OK, never again. No regrets, we’re still great friends.”

The Rolling Stones are currently on their ’50 & Counting’ tour and were joined onstage by Katy Perry at their show in Las Vegas Jasa Roll Plat earlier this month (May 11), with her and Mick Jagger performing a duet of ‘Beast Of Burden’ – click at the bottom of the laman to see fan-shot footage of the collaboration. The band return to the UK for their Glastonbury headline set on June 29 and a pair of massive gigs in London’s Hyde Park on July 6 and 13.
