Cutting movement prevention device and method in spindle stationary state of machine tool

摘要

Cutting movement preventing device and method of spindle standstill of machine tool;In order to prevent workpiece defects, tool damage and machine damage by monitoring the spindle status in cutting feed mode at all times and stopping the movement of the axis when the spindle is stopped and alarming.;The prevention device includes a spindle unit having a sensing unit that detects rotation of the spindle of the machine tool, and a machining program to instruct axis movement and machining, and to check whether there is no signal input from the sensing unit. And a servo unit for turning on and off the servo function for cutting according to the power panel, and the prevention method includes a method for instructing the machine tool to rotate the spindle and rotate the spindle in order to perform a machining function. 2nd process to check whether the spindle is stopped after the 1st process and the 1st process, and to perform normal machining at the time of rotation, and to check the cutting feed mode if it is stopped at the 2nd process. And a fourth process of stopping the cutting feed and alarming the cutting feed mode in the third process. .;Effect; In the cutting feed mode of the machine tool, the spindle feed also stops when the spindle stops, which prevents workpiece machining defects, tool damage, and machine damage.
