摘要： PURPOSE: To make both the centers of a spindle and a wheel by lowering a tool rest after maing it synchronize with the ascent of the wheel by means of a lifter unit, stopping the movements of the lifter unit and the tool rest at a position where a detecting means has detected its contact with the wheel, and compensating a traveling position of the lifter unit according the outside dimensions. CONSTITUTION: A contact member attached to a tool rest 5 is outputted by a proximity switch at a time when it has contacted with a flange part of a machined wheel 2, and thereby a synchronous lifting motion between a lifter unit 8 and this tool rest 5 is stopped. Next, diametral measurement of the machined wheel 2 is operated by an amount of travel in the tool rest 5 or lifter unit 8, and in consequence of this operation, a fact of whether a diameter of the machined wheel 2 is larger than the reference size or not is judged. If a compensation value is outputted according to this judgment, the lifter unit 8 is made to go up on the basis of this compensation value, and then the center of this machined wheel 2 is accorded with that of a spindle 3a, and thus a center detecting process is over.

摘要： PROBLEM TO BE SOLVED: To carry out the measuring of a knife edge center position in the Y-axial direction of a rotary tool in a simple operation, by providing a touch sensor having contacts in the +Y axial direction and the -Y axial direction. SOLUTION: A worker moves an end mill T2 relatively in the manual mode, it is abutted to a contact 12b in the +Y axial direction side, and he reads the machine coordinates value Y2 of a machine coordinates system at the contacting time, from a moving shaft controller. Then, the worker makes the end mill T2 abutted to a contact 12a in the -Y axial direction in the manual mode, and reads the coordinates value Y1 in the -Y axial direction side from the moving shaft controller. The rotation center position error found from the coordinates values Y1 and Y2 and set data Y01 and Y02 , and the diameter are stored in a memory area of a tool offset memory, corresponding to the correcting number of the end mill T2 .
