  • Patent number: 10675688
    Abstract: A method for machining grooves in the surface of a workpiece in which a dummy groove is machined in the surface of the workpiece by moving a cutting tool relative to the workpiece in a first machining direction of the workpiece, then orienting the cutting tool 180 degrees as compared to the first machining, and subsequently second machining the dummy groove by moving the cutting tool in a second direction opposite to the first direction. A displacement of a cutting edge of the cutting tool, caused by the first and second machining of the dummy groove is measured. A groove is machined with the cutting tool in a forward stroke and then a return stoke with the cutting tool rotated 180 degrees between the strokes. A relative position between the workpiece and the cutting tool during the forward and return strokes is corrected so as to eliminate the displacement.

  • Publication number: 20190321929
    Abstract: A machine tool includes a mounting table, a tool, a shade detector, and a tool controller. A workpiece is placed on the mounting table. The tool includes a tip. The shade detector is fixed on the mounting table, provides an optical path of a laser light, and detects a shade state of the laser light. The tool controller is connected to the mounting table via a supporting structure and controls an orientation and a position of the tool. A reference point associated with the tool is provided to the tool controller. The tool controller corrects a position of the tip based on a difference between a position obtained by calculation of the reference point in the case where the tip is matched with a measurement position P of a laser light and a position of the reference point when the tip portion is actually matched with a measurement position while keeping the orientation of a tool.
