Abstract
Because of existing non linearities, time-varying parameters and uncertainties in turning processes, it is difficult to obtain satisfied performances for modeling base control methods. In this paper, the model-free PID control method with neuron tuning gain is prosed for a constant cutting force metal turning process. In order to reach the purposes of enhancing the control system stability and improving the dynamic performances, the model-free PID control method keeps the cutting force to be constant by using the neuron to change the controller gain on-line when a cutting tool cuts at various cutting depths or the spindle operates in different speeds. These simulation results of using the proposed controller for a cutting process show that very strong robustness, good disturbances resistant and satisfied performances are obtained. This control method is very simple and can be easily implemented in practical cutting processes.
