The cutter is usually shaped like a drill bit or endmill, with teeth that cut into the material as the tool rotates.
5-axis machining is a cutting technique that allows for greater flexibility in the way the tool approaches the workpiece. The term “5-axis” refers to the number of directions in which the cutting tool can move. On a 5-axis machining centre, the cutting tool moves across the X, Y and Z linear axes as well as rotates on the A and B axes to approach the workpiece from any direction.
CNC mills use computer numerical control (CNC) software to control their operation. This software reads data from CAD/CAM files generated by other programs and translates that information into instructions for controlling the machine’s motors and feed rates.

CNC turning machines can be used for both small and large batches, depending on the machine you use. The machine will remove excess material from your bar stock by using a rotating cutter called a toolpath. The toolpath will follow an outline or pattern on a computer-aided design (CAD) file that has been created in advance by your CAD/CAM software.
The software will also calculate how much material needs to be removed based on how deep or shallow you want your cut. You can then tell your CNC controller where on each part to start cutting and where it should stop, so that it creates a finished part with no wasted material left behind.
Sliding Head Turning
These machines were first designed for producing precision watch parts and other mill-turn components within exceptionally close geometric tolerances. As such, they have been used in many industries over the years since their inception.
Today, they are most commonly used to manufacture aerospace parts and medical devices. Sliding head machinery is capable of performing machining operations with extreme accuracy by allowing the workpiece to move in the Z-axis while the tool remains stationary. This is unlike traditional lathes where the workpiece remains in position while the tools move around it. The benefit of this is increased precision and reduced process time.
Metal fabrication is a broad term referring to any process that cuts, shapes, or moulds metal material into a final product. Metal fabrication is often pursued through computer-aided designs (CAD) programmed using computer numerical control (CNC) technology. Rather than an end product being assembled from ready-made components, metal fabrication involves the creation of an end product from raw or semi-finished materials.
Casting is one of the oldest methods for making metal parts and has been used for over 4,000 years. Casting involves both ferrous materials such as cast iron and ductile iron as well as non-ferrous materials such aluminium casting alloys and copper casting alloys. The process consists of pouring liquid metal or other materials into a mould and allowing it to cool and solidify in that shape.
The main advantage of casting over other methods of forming metals is its low cost compared with machining or forging processes which require more energy-intensive operations such as cutting or stamping out shapes from sheets of metal stock by pressing them between dies under pressure (forging).
The forging of metals is one of the oldest working techniques of humankind, dating back thousands of years, with a wide range of metals being susceptible to forging techniques. Forging involves the use of compressive forces and is often categorized according to the temperature at which it is performed – cold, warm, or hot forging.
Forging can increase the properties of metal including structure, conductivity and longevity and is consequently an extremely effective method for producing high quality and durable metal products.
Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. One of the electrodes is called the tool-electrode, or simply the tool or electrode, while the other is called the workpiece-electrode, or work piece.
The process depends upon the tool and work piece not making physical contact. When the voltage between the two electrodes is increased, the intensity of the electric field in the volume between the electrodes becomes greater, causing dielectric break down of the liquid, and produces an electric arc.
As a result, material is removed from the electrodes. Once the current stops (or is stopped, depending on the type of generator), new liquid dielectric is conveyed into the inter-electrode volume, enabling.
Surface grinders use an abrasive wheel and a work-holding device known as a chuck. The chuck holds the material in place while it is being worked on. It can do this one of two ways: ferromagnetic pieces are held in place by a magnetic chuck, while non-ferromagnetic and nonmetallic pieces are held in place by vacuum or mechanical means.
A machine vise (made from ferromagnetic steel or cast iron) placed on the magnetic chuck can be used to hold non-ferromagnetic work-pieces if only a magnetic chuck is available.
