Research on the Testing System of Dynamic Indexing Accuracy of Indexing Machine

This paper deals with the establishment of a testing system for dynamic indexing accuracy by using a circular raster sensor and direct measuring method. On the basis, the method of measuring dynamic indexing accuracy is studied by taking the high speed indexing transmission mechanism as an example. The testing system has the function of measuring the indexing accuracy of indexing machine on line and its highest testing accuracy can reach several arc·second.
