The Modern Measurement Technology for the Jump Error in the Specific Position and Aperture of Tiny Revolving Part

摘要

Aimed at irregular shape tiny revolving part, in the circumstances of mass production, consider the difficulties of contact detection, put forward the non contact detection method based on optical triangle test principle, photoelectric switch principle, grating displacement measurement principle and CCD image technology and auto-focusing technology, etc. Achieve the measurement of the specific location bounce error and aperture in bottom. It eliminated the influence of artificial factors in the traditional measuring method.
