Quick Summary

A gear shaper is a machine tool designed for shaping gear teeth. It utilizes a cutter that has the form of a pinion gear. This method is a type of gear-generating machine that cuts with reciprocating strokes.12

Gear-cutting machines employ different methods, including form cutting, template cutting, and generating. The generating method, used in gear shapers, is based on the principle that two involute gears can mesh properly. This allows a cutting tool shaped like a gear or rack to cut teeth in a gear blank.2

Gear cutters can also refer to the machines themselves or to a specific milling cutter shaped to cut gear teeth. The tools used in these machines must be harder than the workpiece and capable of maintaining a sharp edge at high temperatures generated during the cutting process.34
