Abstract
A touch-trigger probe is described having a workpiece-contact sensor () in the form of a kinematic seating () and workpiece contacting stylus (). A processor μP in the form of a reprogammable PIC microcontroller is used to monitor the signal from the sensor (). When the signal is above a threshold for a continual period of time (CT) then the processor issues a trigger signal. The monitoring of the time period (Ct) may be delayed. This delay (Ci) allows triggering initiated by the shock wave produced initially when workpiece contact occurs.
