Study on the Technology of Noncircular NC Turning

CAO Hui, YAO Xiaopeng, GONG Wei(School of Manufacturing Science and Engineering,Southwest University of Science & Technology,Mianyang 621010,CHN)  
Based on the characteristic of noncircular turning, a variable rank angle mechanism driven by high frequency linear servo motor was established.The kinematics mechanism motion rule was analyzed and the constant rank angle was realized.The tool feed synchronized the workpiece rotation by using time-base method of PMAC and achieved the noncircular auto turning.This method had applied in noncircular NC lathe.The result shows that it can improve the precision and efficiency of noncircular turning.
