Method and equipment for detecting tool failure

摘要

In a machine tool, a tool failure detection equipment in which chips or particles resulting from the machining of a work are collected and whether the tool is intact or broken is detected from the quantity of collected chips or particles. Chips or particles are sucked by a suction means and the quantity of collected chips or particles is detected by an optical detecting means. When the detected quantity is less than a predetermined value, the tool is detected as being broken.
