PURPOSE: To make it possible to automatically input the distances of touch sensors from the original point and the coordinate offset value of a tool to be measured, by arranging four tools adapted to cope with tools to be measured, having various shapes, in four directions.
CONSTITUTION: A sensor section includes two touch sensors in the directions of the X- and Z axes, respectively. That is, four touch sensors, that is, X-axis positive side sensor 11x, X-axis negative side sensor 12x, Z-axis positive side sensor 11z and Z-axis negative side sensor 12z, are provided around a sensor core 10. In this arrangement, an objective tool 51 is made into contact with a designated sensor, and is made into contact with a correctly corresponding sensor. If the sensor is the correct one, a touch sensor signal is issued to carry out computation, and the thus obtained numerical value is stored in a memory section. The above-mentioned process is carried out for the X-axis and the Y-axis, and therefore, the offset amount of position of the cutting edge of the tool is measured and stored in the memory.
