4. GRINDING MACHINE 4.1 Introduction Grinding is a metal cutting operation like any other process of machining removing metal in comparatively smaller volume. The cutting tool used is an abrasive wheel having many numbers of cutting edges. The machine on which grinding the operation is performed is called a grinding machine.

A large number of studies have shown that the height of a residual material is the key factor affecting the surface quality of ultra-precision grinding. However, the grinding process contains several random factors, such as the randomness of grinding particle size and the random distribution of grinding particles, which cause the complexity of the material removal process.

other types of milling machines, shown is the vertical milling machine. • A milling machine removes metal by rotating a multi-toothed cutter that is fed into the moving workpiece. The spindle can be fed up and down with a quill feed lever on the head. • The bed can also by fed in the x, y, and z axes manually. Once an axis is

Machining centers can be broadly classified into three types based on their structure: horizontal, vertical, and gantry types. The horizontal type—the first to be developed—can be defined simply as a machine where the spindle to which the cutting tool is attached is mounted horizontally (or parallel to the floor).
