Abstract

PURPOSE:To enable highly accurate machining in a depth direction by storing the temperature change and the expansion/contraction quantity of a tool caused by the rotation/stoppage of a spindle, measuring the time of rotation/stoppage of the spindle while obtaining the expansion/contraction quantity of the end position of the tool, and applying a corrected quantity to a control device. CONSTITUTION:The relation between the time of rotation/stoppage of a spindle 12 and the displaced position of the end of a tool 15 is previously obtained and stored in a third detecting means 22. After setting the moving quantity of the tool 15 based on the outputs of detectors 20, 5 by a control device 21, the spindle 12 is rotated to start machining. At this time, the detecting means 22 measures the rotating time of the spindle 12 while outputs the displaced quantity of the end of the tool 15 corresponding to that time to the control device 21. Thereupon, the control device 21 controls a machining device while correcting the moving quantity of the tool 15 based on a signal applied from the detecting means 22 to carry out machining.
