A micromachining process for performing microscopic forming using tools or dies to compress or impact a material.

There is strong demand for high precision in forging, and this is developing toward reducing after-processing stages to the minimum and toward so-called near-net-shape forming. Most microcomponents are not completed by forging only, but forging is used in some processing stages. An example is the production of the steel balls for bearings. Cut round rods are initially forged to a spherical shape by a compression forming (plastic working) stage. Subsequently, the balls are completed by grinding, heat treatment, and lapping.
