Title:
ROTARY TOOL WITH STRESS-LUMINESCENT MATERIAL, MANUFACTURING METHOD THEREFOR, AND MACHINE TOOL CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/033338
Kind Code:
A1
Abstract:
Provided are: a rotary tool with which tool breakage and machining resistance can be detected even during machining even in machining in which the machining load is small such as with a small diameter tool; and a machine tool control system capable of controlling a machine tool according to machining load. The rotary tool is for cutting or grinding a workpiece and has a member comprising a stress-luminescent material on a portion of the tool surface. The machine tool control system comprises a light-receiving unit for measuring the emitted light intensity of the stress-luminescent material provided on the rotary tool, a calculation unit for calculating feed rate instructions according to the emitted light intensity, and a machine tool control unit for transmitting a signal to control the machine tool according to the calculation results, and controls the machine tool so that the emitted light intensity of the stress-luminescent material approaches a previously determined value.
