Abstract
The invention is directed to a method for automatically generating travel paths to the next geometric elements to be measured when there is a collision of the probe 25 or the probe head 10, for example, with the workpiece 22. The method utilizes safety-reference surfaces (S1 to S5) placed in the form of an enclosing parallelepiped about the workpiece 22. The shortest collision-free connecting paths (P1-P2-P3) from one geometric element to the next are computed on these safety-reference surfaces.
Claims7
A method of controlling a coordinate measuring apparatus for making measurements on a workpiece utilizing a probe, the workpiece having a plurality of geometric elements on first and second sides thereof and the apparatus having a fault-handling device for interrupting a measuring sequence in the case of a disturbance and for resuming the measurement sequence in a modified form, the method comprising the steps of:
- coupling a control module to said fault-handling device;
- placing predefined safety-reference surfaces about the workpiece;
- automatically generating a travel path with said control module for said probe between said geometric elements utilizing said safety-reference surfaces;
- and,
- at least always automatically computing in said control module collision-free connecting paths on said safety-reference surfaces from one geometric element on said first side to a next one of said geometric elements when said next geometric element is on said second side of said workpiece.
