The linear motion of CNC machine is generally converted from rotary motion of servo motor through a ball screw nut pair.As most CNC machine is controlled by semi-closed loop system, ball screw nut pitch error is among the main factors influencing machine positioning accuracy.A method is introduced in this article for CNC linear axis pitch error measurement and compensation by using RENISHAW XL30 laser interferometer.Experiments based on HNC-818B vertical machining center show that bidirectional pitch error compensation for ball screw drive mechanism applying this method can greatly improve the machine positioning precision.
