DEVICE AND METHOD FOR CORRECTING THE POSITION OF A TOOL DIE OF A MACHINE TOOL, CAPABLE OF CORRECTING THERMAL ERRORS

摘要

PURPOSE: A device and method for correcting the position of a tool die of a machine tool are provided to correct thermal errors by attaching a touch sensor for a tool setter to the side surface of a headstock and monitoring the X-axis displacement of a headstock and a tool die.;CONSTITUTION: A device (100) for correcting the position of a tool die of a machine tool is composed of a headstock (120), a tool die (130), an electric motor (140), a touch sensor (150), and a computer numerical value control unit (160). The touch sensor is installed on the headstock and outputs a touch signal when the tool die touches the touch sensor. When the touch signal is inputted to the computer numerical value control unit, the computer numerical value control unit reads a position value corresponding to a transfer distance and defines the read position value as an offset value.;COPYRIGHT KIPO 2013;[Reference numerals] (120) Headstock; (130) Tool die; (160) Computer numerical value control unit; (161) AD converter; (162) Motor drive unit; (163) Position detection unit; (164) Control unit; (165) Storage unit; (166) Correction value calculation unit
