| Abstract: | The relationship between cutting forced-induced errors and the spindle motor current was analyzed based on kinematic chain of NC machine tools,and then the cutting force-induced error model was constructed using BP neural network and particle swarm optimization.The cutting force-induced error compensation system was developed based on the cutting force-induced error model and verified through a machining experiment.The neural network modeling has better compensating effect and is more robust.The compensation system is of importance to precision manufacturing industry. |
