1. Purpose of chipping

Chipping is working on materials by a wedge-shaped tool (the chisel) in order to separate or chip material. The cutting effect of the chisel is achieved by hammering on the head end of the chisel, which is an energy and time consuming operation.

Chipping therefore, is useful only if other mechanical working techniques cannot be applied or are not worthwhile.
