Research on Method of Process System with Error Tracing Based on PSO

In machining process, the machining systems are usually described by the stable theoretical model. However, there are still various process errors existed. To recognize, compensate and eliminate the errors, a method of process system error tracing based on PSO is proposed to explore the errors existing in the machining process. The determined theoretical model is defined and actual measurement data samples are used to find the optimal solution, get the deviation value of each error sources. Finally, the process system error tracing of the Arc Cam is taken as an example to prove the stability and validity of proposed method.
