Tool measuring method for machine spindle - measuring spindle stock position when tool enters optical measurement plane using laser light barrier

摘要

The tool (14) is moved between a spindle stock and a workpiece table. The relative position of the spindle stock to a reference point is measured by a displacement measurement system. The tool is moved in the direction of one of its coordinates to an optical measurement plane perpendicular to these coordinates. The measurement system produces a signal when the tool enters the plane, and the instantaneous spindle stock position is measured. The tool dimensions are then derived from the measured position and the relative position of the measurement plane to the reference point. The procedure is also conducted in a coordinate direction transverse to the longitudinal direction of the tool. USE/ADVANTAGE - For measuring tool in machine spindle. Increased accuracy and reproducibility.
