Research of Roundness Auto Detection Based on Error Separation Technique

Analyzing the additional measuring error caused by position error which is an eccentricity between geometric center of the measured section and turning center in the process of roundness test,it indicates that the influence of additional error will be reduced with the enhancement of sensor resolution.However,in course of on-site industrial measurement,the enhancement of sensor resolution is often limited by product cost.Hence,it is a necessary to carry out the method of measurement based on position error separation and compensation in the process of roundness test.Furthermore,it introduces the working principle of the automatic testing system for roundness based on error separation technique,the composition of roundness evaluation system as well as a test example which illustrates that with error separation technique the testing accuracy is improved significantly.
