- Abstract:
- It is described how to calibrate the kinematic parameters of a parallel CMMs, in this paper. The artefact which consists of spheres is selected as physical constraints for self-calibration. The kinematic calibration of the parallel CMM is performed using the artefact of two spheres. The parallel CMM can measure a sphere in a lot of different orientations so that a lot of sensor information can be got at the identical location. If the number of sensor information is larger than that of whole parameters, e.g. the kinematic parameters and the orientation and location of stylus, the whole parameters can be self-calibrated without any information of artefacts. Two type of parallel CMMs are considered. The model equation of CMMs and the allocation of spheres are discussed. Finally, best allocations of spheres are proved.
