Gear cutting and grinding processes

Gear production is characterized by two main functions:

• the cutting function to remove material;

• the toothing function, either by direct reproduction or by generation; in the latter case, the cutting motion laws are closely linked to the often complex kinematic processes.

It's on the basis of a set of specifications, or at least a definition plan, that the gearmaker will learn about the product to be produced. The overall cost, the quality level, the quantity to be produced per unit of time, the reliability of the equipment used, etc., will complete this data.

This article is a simplified presentation of the machines available on the market, and gives an overview of the cinema-tic chains used in CNC production.

The list of equipment described in this document is not exhaustive.
