Cutting as a mechanical process is the removal of material resulting through use of force, typically shear and compressive. Although "cutting" is certainly a cutting process, grinding, milling, and drilling are also cutting processes as they result in material removal through the application of appropriate forces.

Mechanical milling is used to change the properties of silver powders, including disintegration of particle aggregates, particle shape, and particle surface characteristics. This process can be used for most types of silver powders with techniques such as ball milling, vibratory milling, or attrition milling.

The CNC Mill can machine many different materials, examples are steel, aluminum, brass, copper and plastic. A Mill is not designed for cutting wood and should not be used for that. Examples of operations that can be made in a CNC Mill is to cut a profile shape, engrave text, mill a 3D surface, drill holes and mill bearing pockets.
contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes. The more flutes, the more cutting edges but the

CNC Machining . Intro to CNC Machining • CNC stands for computer numeric controlled. It refers to any machine tool (i.e. mill, lathe, drill press, etc.) which uses a computer to electronically control the motion of one or more axes on the machine. • The development of NC machine tools started from a task supported

A CNC Milling Machine uses a rotating cylindrical cutter to move along multiple axes, and create slots, holes, and details in material to turn it into a vehicle or mechanical part. Most machines operate on three to five axes, creating much more precision and detail.
In mechanical milling (MM), a suitable powder charge (typically, a blend of elemental) is placed in a high energy mill, along with a suitable milling medium. The objective of milling is to reduce the particle size and blending of particles in new phases.

Electro Discharge Machining (EDM) is an electro-thermal non-traditional machining process, where electrical energy is used to generate electrical spark and material removal mainly occurs due to thermal energy of the spark. EDM is mainly used to machine difficult-to-machine materials and high strength temperature resistant alloys.
An aluminum block of length 50 mm and width 70 mm is being milled using a slab milling cutter with 50 mm diameter. The feed of the table is 15 mm/min. The milling cutter rotates at 60 RPM in clockwise direction and width of cut is equal to the width of the workpiece. Draw a neat sketchof the milling operation describing aboveconditions.
