Paper Abstract

This paper describes an online noncontact metrology system for tool misalignment detection on the Opticam spherical surface generator. The system detects distortion due to surface errors in the reflected image of a bar target. The amount of image distortion is determined by the relative slope changes on the test surface, and it can be calculated as a phase function of the reflected image. The phase function can be used to determine surface slope variation of the test part, and this slope information can be used to determine the cutting tool misalignment in the Opticam system.
