Scope
This document specifies test requirement, test methods, and tolerance for testing the geometric accuracy, the accuracy and repeatability of positioning of numerically controlled axes (linear & rotary), and the machining accuracy on cylindrical gear grinding machines. It is applicable to worm wheel gear grinding machines and form gear grinding machines (hereinafter referred to as "machine tools").
Purpose
Plentiful types and technologies of gear cutting machines ascribed to higher demands on transmission stability, transmission ration accuracy, load capacity and work reliability of gears. It is beneficial for improvement of trade efficiency and service experience by proposing global common criteria. Additionally, the only one gear hobbing machine standardISO 6545 has lost its applicability under the condition of replacement of key control technology in the field of gear cutting machines.
