ERROR SEPARATION METHOD FOR ROUNDNESS MEASUREMENT

J.-C. Zhang, Y.-X. Cheng

Abstract

This paper describes a new error separation method for roundness measurement. It can be used in precision roundness measurement instrument. The spindle rotary error and work-piece roundness error can be separated by this method. This method using one sensor and one indexing of the workpiece for each measurement. Compared with other error separation methods the measuring efficiency and uncertainty can be improved.
