    摘要: The present invention relates to a method of controlling a numerically controlled machine tool having a plurality of feed shafts. Also, the present invention relates to a numerically controlled machine tool. According to the present invention, it is possible to solve conventional problems so as to realize highly accurate machining even when a moving body of the machine is moved at high speed. As the means for solving the problems, an appropriate command corresponding to a frictional force of the feed mechanism of the numerically controlled machine tool and also corresponding to a change in the weight of a workpiece is estimated by calculation, and the thus estimated command is outputted into the drive unit of the feed shaft motor so as to drive the feed shaft motor.
