COURSE OVERVIEW:

Machining is any process in which a cutting tool is used to remove small chips of material from the

workpiece (the workpiece is often called the "work"). To perform the operation, relative motion is

required between the tool and the work. This relative motion is achieved in most machining

operation by means of a primary motion, called "cutting speed" and a secondary motion called

"feed". The shape of the tool and its penetration into the work surface, combined with these

motions, produce the desired shape of the resulting work surface.
