METHOD FOR CORRECTING A POSITION OF A TIP OF A MACHINE TOOL
First Claim
1. A method for correcting a position of a tip of a machine tool, wherein the machine tool comprises:
- a mounting table on which a workpiece is placed;
a tool configured to machine the workpiece placed on the mounting table, the tool including a tip;
a shade detector fixed on the mounting table and configured to provide an optical path of a laser light and detect a shade state of the laser light; and
a tool controller connected to the mounting table via a supporting structure and configured to control an orientation and a position of the tool,wherein a reference point associated with the tool is provided to the tool controller, andthe correction method comprises;
a matching process in which the tool controller actually matches the tip of the tool with a measurement position of the laser light, while keeping a first orientation which is an orientation of the tool for machining, the matching being based on the first orientation and a length of the tool; and
a first tool position specifying process in which a first tool position, which is a position of the reference point in a state in which the tip is actually matched with the measurement position of the laser light, is specified.

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.
