| Abstract: | The difficulties in control of machining processes come form the uncertainty and nonlinearity in cutting processes, and which result in becoming the bottleneck for applying automatic control to machining. In this paper, Uncertainty in cutting force models is analyzed. And performance of machining process control systems is analyzed by proposing an approach based on variable structure control (VSC). The research results show that VSC is a reasonable and effective way to deal with the uncertainty in milling process. |
