Research on intelligence inspections of gear profile deviation

Gear profile deviation means deviation of actual gear profile compared with normal gear profile which is calculated in the gear end plane erected with gear involutes. And it is a main project for assessing moving tranquility. But tradition measuring machines couldn't own universality well, and they were prone to being impacted by human beings. The paper shows a new method that DMIS programs for inspecting gear profile deviation can be generated automatically in Pro/CMM software according to CAD model of gear and then coordinate measuring machine will be driven by them to inspect gear profile deviation. The measurement method can achieve high-precision measurement collection points, high efficient measurement process, less manual intervention and low-level error.
