Study on Accuracy Stability of Machining on CNC Machine by Compensation of Transmission Error Caused by Wear of Ball Screw

Authors: Trần Đức Toàn *


The machining accuracy of products on CNC machine depends on many factors appearing before, during and after machining. The translational movement during processing was performed by ball screw. Therefore axial movement error of ball screw directly decides processing error. This article presents a determining method of movement error for ball screw to improve machining accuracy on CNC machine.
