Notes:
This paper advances a method to implement the on-machine measurement (OMM) withthe touch-trigger probe, also called switching probes. Some of the advantages and disadvantages fortouch-trigger probe are discussed. However, the touch-trigger probe errors exist and become one ofthe major errors for the measurement accuracy. Major factors that influence the probe measurementhave been analyzed. The basic technique of probe measurement error modeling with artificial neuralnetwork was researched, and also the probe measurement error compensation with 3-layered backpropagationartificial neural network was presented. At last in the experimental system composed ofDIXI 50 machining center, Fanuc 16i control system, Blum CNC P82.046 probe and PC, valid thecorrelated techniques. In addition, the connection and communication between the machining centerequipped with probe system and the computer have been introduced. The experiment indicated that,using the touch-trigger probe makes on-machine measurement more automatic and efficient. Andby using the back-propagation neural network for error compensation make on-machinemeasurement more precise
