The Automatic Measure For The Circular Hop Error In The Specific Position Of Tiny Workpiece

In this paper, the bomb core is a tiny, irregular, revolving, mechanical part. Under the condition of production on a large scale, it is difficult to measure the bomb core by contact measurement. So we adopted optical-triangle measurement principle, grating displacement measurement principle, etc. According to these principles, we can achieve non-contacted measurement for the circular hop error in the specific position of bomb core.
