Abstract
A new metrology technique was developed for on-line tool misalignment detection. It is an image based metrology system. It measures surface slope functions from the captured reflected image off the test surface. The measured surface slope function is then used to determine the corresponding tool misalignments in the ring grinding setup for the Opticam surface generator. A prototype detection system was built and tested on-line in the Opticam machine. The experimental results are presented in this paper.
