Prediction of machining accuracy degradation of machine tools

open access: yesPrecision Engineering, 2012
Abstract Machine tool has to maintain its accuracy for quality control of products. After a long period of cutting operations, obvious wear will occur on the contact surfaces of the slide and the guideway. Such a wear will degrade the accuracy of machine tool due to the increase of Abbe errors.
