Özet

A novel touch-trigger probe system is proposed in this paper. The probe houses the stylus shaft on a special diaphragm spring that is exclusively designed with the utilization of Finite Element Analysis (FEA). In the probe system, Giant Magneto-Resistive (GMR) sensors are employed to measure the motion of the stylus shaft in the principal directions. The proposed (and implemented) probe is tested on a three-axis CNC electrical discharge machine (EDM) and the results acquired from those experiments are discussed. The preliminary work presented in this paper demonstrates the capabilities of GMR based probing technology in dimensional metrology.
