Measuring of positioning, circularity and static errors of a CNC vertical machining centre for validating the machining accuracy

A CNC machine tool performance depends on the machine accuracy status which is very important to determine the end product compliance to the specification. The accuracy of the machine can be measured and analyzed; hence the errors' impact can be predicted on a workpiece. This paper presents thr...
