A Study on High-precision Machining by Measurement and Compensation of Motion Error
Daisuke Kono, Atsushi Matsubara, Yasumi Watabate
Nowadays, rectification machining process is used to achieve sub-micron-order geometrical accuracy in cutting.
To avoid measurement errors due to reproducibility of workpiece position, on-the-machine measurement is
used. However, motion errors of machine tools could not be detected by using on-the-machine-measurement. In
order to solve these problems, motion errors in machining process are measured and compensated. In this
paper, straightness error is measured, modeled, and compensated on a machine tool with ball screw system.
