Mechanical Technology: Fitting & Machining : Grade 12

Mechanical Technology: Fitting and Machining includes turning, milling, cutting, shaping, fitting of keys, couplings, bushes, shafts and bearings; Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, moves more or less linearly while the work piece rotates. Milling operates on the principle of rotary motion. A milling cutter is spun about an axis while a work piece is advanced through it in such a way that the cutters are able to shave chips of material.
