Measuring method of correction value of position measuring sensor in machine tool and correction value measuring system

摘要

Problem to be solved: to obtain a correction value of the length and diameter of the position measuring sensor without time and labor.After the detection position of the reference tool and the optional tool measurement position are acquired using the touch sensor, an arbitrary probe measurement position is acquired using a touch probe. The length of the touch probe is obtained based on the difference between the tool measurement position and the sensor measurement position and the length of the reference tool.The position of the reference sphere is measured using the touch probe, and the relative position of the reference sphere relative to the detection position is calculated from the detection position of the reference tool, the position of the reference sphere, the length of the touch probe, and the length of the reference tool.Then, the position of the reference tool is acquired using the tool sensor (S1), and the position of the reference sphere is measured using the touch probe, and the length direction correction value of the touch probe is calculated from the position of the reference tool, the position of the reference sphere, the relative position, and the length of the reference tool (S3). The radial correction value of the touch probe is calculated using the position and diameter of the reference sphere (S4, 5).Diagram
