In the internal thread grinding process, it is difficult to control the feed size because there is no accurate thread pitch diameter measurement tool for online inspection. At present, the process is measured with a master thread plug gauge, but the large size and weight of the large thread master gauge make it difficult to test the operation. Since the thread plug gauge can only be qualitative measurement, and can not achieve quantitative measurement, it is difficult to control the feed size during the thread grinding process, resulting in high scrap rate and low efficiency.
By introducing the online diameter measurement method and comprehensive measurement method in the processing, the online quantitative detection of the pitch diameter of the thread ring gauge can make the accuracy and efficiency greatly improved.
