Study on the Calibration Method for Double Ball System

Abstract

Ball bar system is a useful tool for checking the machine tool performance. However, its total accuracy including dynamic performance have not checked and its method also does not established yet. This paper describes the methodology of the total calibration of double ball bar especially to calibrate its dynamic performance. The proposed system can check the transient performance of the ball bar system with software data treatment systems. The developed system can generate feed in and feed out motion for software trigger mode by the electro-magnetic actuator. This system can evaluate the ball bar system's total performance that include mechanical properties and software characteristics including digital sampling performance. The developed system will be useful to improve conventional systems.
