Abstract: In order to fulfill the thermal error modeling of precision abrasive machining, a neural networks model is presented through analyzing thermal error sources of the grinding machine, the structure and algorithm of the neural networks is expatiated then；And because of reasonable sample and systematical training, the accuracy of thermal error models is improved. The hardware system for thermal error compensation is proposed finally, and an experiment is accomplished on the grinding machine. The result shows thermal errors is reduced from 6μm to 1μm.

Abstract: Aimed at the requirement of a project, a man-machine cooperation(MMC) manipulator was designed based on its system structure and man-machine function analysis. Meanwhile, the system functions were allocated between man and manipulator, and in order to realize information integration in MMC material handling system, a application method of mechatronics was discussed. Then an example is given to express one of the realization methods of information communication between man and manipulator.
