Improvement of Angle Deviation at Tilting Rotary Table of Five-axis Machining Center.

Abstract

This paper proposed the improvement method of the angle deviation at the tilting rotary table of five-axis machining center. The angle deviation at the tilting rotary table induced by the offset load of work is the major disturbance of five-axis machining center. However, the factor causes this problem has not been clarified. In this research, the angle deviation and rotary drive torque were measured with tilting rotary table added the offset load. From the experiment result, Relation among the angle deviation, the offset load, and the rotary drive torque was clarified. The experiment model that was able to estimate the angle deviation was obtained.
