Machining is one
manufacturing process

Machining is one secondary manufacturing process where excess material is gradually removed from the workpiece in order to impart desired shape, size and finish.

There are various types of machining processes including conventional machining (like turning, milling, drilling, facing, etc.), non-traditional machining (like AJM, USM, EDM, ECM, CHM, LBM, etc.), abrasive cutting (like grinding, lapping, honing, etc.) and micro-machining (like micro-milling, precision turning, micro-drilling, etc.). However, every machining process follow the same basic principle of gradual removal of excess material from workpiece (this machining is one subtractive manufacturing process).
