In the same type of parts measurement tasks,,there are one-time inspection batch parts in addition to a single piece of inspection parts. Tasks can not be finished according to the original pian.In order to measure accurately and efficiently, the method of improvement should be studied. Through the study of typical parts such as rotating parts the impact of measurement points, influence on the measurement results of the design of fixed fixture, coordinate system, design programming module, realize batch parts more than at the same time continuous automatic measurement and measurement results of automatic text output, set up automatic measuring method of batch of key parts. It ensures the accuracy of measurement results, improves efficiency, reduces labor intensity, and the effective guarantee for scientific research and production is provided.
