The grinding of gears with dish wheels (Maad type grinding machines) is widely viewed as the most precise method of gear grinding because of the very short and simple kinematic links between the gear and the tool, and also because the cutting edges of the wheels represent planar surfaces.

This kinematic analysis is done for the example of a double-side fine grinding machine, type Duomat ZL 700, Hahn & Kolb , Schorndorf (now Stahli Lapp-Technik , Schonaich). The outer pin circle of this machine is fixed, whereas the two grinding wheels and the inner pin circle can be driven individually.

3.1 INTRODUCTION. Material removal by grinding occurs mainly by a chip formation process, similar to that of other machining methods such as turning or milling, but on a much finer scale.
