Thread Pitch Error Measure and Compensation in CNC Machine

Fang Chen

Abstract

The principle of measuring linear errors with laser interferometer was analyzed.A method of measuring and compensating the opposite clearance and thread pitch errors with laser interferometer was proposed,and an application example was presented.According to the practice data,the method is proved effective to improve the CNC machine tool processing precision.
