In the case of the numerical controlled (NC) machine tools, the position Accuracy is one of the most important items required to be-inspected. The NC vertical milling machine installed in 1978 (MAKINO KGNCC-60 type) has three controlled shafts, that is, both X axis and Y axis controlled with complete closed loop and Z axis controlled with semi-closed loop. In this NC milling machine, the tests of the postion accuracy during idle running and the cutting tests are carried out. From these test results, it becomes clear that the difference of the position accuracy exists between the axis controlled with complete closed loop and that controlled with semi-closed loop, and the position accuracy during idle running shows a similar tendency to the working accuracy.
