| Abstract: | If a measured workpiece is of a small size and located in the optimal measurement area,the high precision measurement result can be realized by using a low-precision measuring machine.To obtain the optimal measurement area of the articulated arm coordinate measuring machines,the measuring space of articulated arm CMM is given,and its spatial error distribution model is build by using support vector machine theory.The two solutions of the optimal measurement area are discussed and solved through experiments.The results show that the cone socket average distance at the optimal measurement point P1 is 0.1299 mm,but the comparison point P is 0.2048 mm.It is believed that the study on optimal measurement area of articulated arm CMM based on support vector machine is effective. |
