method for measuring a tool of a numerically controlled processing machine with automatic tool change and the establishment of the implementation of this procedure

摘要

The worktool (7) to be measured is moved into a predetermined measuring position, in which it interrupts a measuring beam (15) of a measuring device. The measuring beam (15) is oriented at an angle alpha to the x-y coordinate system of the machine tool. A multi-spindle head having a plurality of axially parallel worktools (7) is moved in such a way that the worktools (7) are moved into the fixed measuring beam (15) one after the other. It is thereby possible to sense and measure all the worktools (7) of the most commonly encountered multi-spindle heads (8), using a single measuring beam (15). Even if two worktools (7) are situated in a common horizontal or vertical plane, one behind the other, each worktool (7) is sensed due to the oblique position of the measuring beam (15) to the x-y coordinate system. It is thereby possible to check and monitor the worktools before and after use, for example as regards wear. IMAGE
