Abstract

PURPOSE:To provide possiblity of continuous unmanned operation by fitting two or more tools of the same type in a tool holder and by selecting automatically the tool with remaining life by setting the expected life previously at the stage of selecting tools. CONSTITUTION:Tools are fitted in a tool holder 8, and according to the tool number the life expected to each tool is put in memory in a tool life register 2a of the memory 2 through a setting display 9. A tool selection command in conformity to special regulations fed from the input part 1 is put in the operation part 4 through a control part 5. The operation part 4 is to select a tool available and give an output command to the control part 5. This control part 5 sends the tool selection command number to the output part 3 while the tool selection control part 7 of the machine tool gives a selective action command to the tool holder 8. A timer 10, meanwhile, renews the accumulated registration 2b of the tool in service at certain intervals.
