Development of virtual coordinate measuring machines incorporating probe errors

Abstract In this paper, a comprehensive computer model is described which can be used to predict the volu- metric errors from the parametric errors of the coordinate measuring machine (CMM) and its probing system, for most configurations of CMMs. Several sets of previously unpublished rules have been derived to transform the CMM parametric errors into a corresponding volumetric error map. Thus a virtual CMM has been developed, implementing the integrated volumetric error model. The developed system has been applied to two practical configurations of CMM, in order to demonstrate the performance and practical application of the system.
