Abstract
In the measurement of workpieces on a coordinate measuring machine having a work-contacting probe head of the switching type, the course over time of the contact signal is stored within a time interval which at least spans the procedural time of contact-signal development. After comparison or correlation with a prerecorded sample signal which has also been stored, the exact time of initial contact or the exact scanning coordinates are then subsequently computed.
