Touch Trigger Probe Interface With Timestamped CNC Event Packets

The patent replaces the traditional mechanical timing system (relying on constant velocity assumptions and fixed time delays) with a digital information system. Timestamped digital data packets carry precise timing information, allowing the measurement system to accurately determine probe event positions without assuming constant machine velocity. This substitution of mechanical timing with digital timestamping resolves the contradiction by achieving high measurement accuracy through information processing rather than mechanical precision.

The patent extracts the timing information from the velocity assumption model. Instead of relying on the constant velocity assumption to calculate positional corrections, the system extracts precise timestamp data from digital packets. This extracted timestamp information directly provides the timing needed for accurate position determination, eliminating the need for velocity assumptions and their associated inaccuracies while maintaining simplicity.

The patent merges multiple pieces of information into single timestamped digital data packets. Each packet contains the probe event timestamp, machine position data, and event type information all combined in one transmission. This merging approach allows comprehensive measurement information to be transferred efficiently in a single communication act, achieving high measurement accuracy without proportionally increasing communication time or data volume.
