An On-Machine Measurement System for Cylindricity Error


A method to implement the on-machine measurement (OMM) with the touch-trigger probe, also called switching probes is advanced in this paper. Some of the advantages and disadvantages for touch-trigger probe are discussed. An objective function is proposed in this paper to evaluate the minimum zone cylindricity error. The error model is optimized by Genetic Algorithm (GA). The mathematical model may work out the minimum zone solution of cylindricity error with arbitrary position in space, and there are no special requirements in choosing measurement points. A case has been given to prove that the OMM system is useful for online inspection compared with Coordinate Measurement Machine (CMM). The approach can also be extended for solving other form and position errors.
