Abstract

PURPOSE: To eliminate an errorneous installing operation performed by an operator by a method wherein a tool type indication part is made in a tool, sensed by a sensor and checked with a tool type number recorded in a machining program.
CONSTITUTION: In a hobbing machining operation, a machining program having a key number corresponding to the number of hobbs is stored as a preparation process. Then, a hobb 1 required for machining a workpiece is selected from a preparation table and then set in a hobbing machine. The type number of the hobb 1 is made to be a code by a sensor 7 with NC energization being made and the hobb 1 being rotated. The coded type number is passed through the scanning circuit 3 and fed to the coincidence circuit 5. In the conincidence circuit 5, the coded type number is coincided with a type number of the hobb read under an instruction from the control unit 6 and in case that a coincidence is found, a selection of the hobb and the preparation process are completed or finished. In case of noncoincidence an alarm signal is generated from an alarm circuit 7.
