Notes:
In order to improve form cutter accuracy in grinding process, a closed-loop controlsystem was designed to accomplish adaptive control of constant force in grinding process. Since itis a complicated dynamic process with severe nonlinear and much stochastic disturbance, fuzzyadaptive controller was used which can adjust parameters online. By measuring grinding force,characteristic information of grinding process was acquired. Regulation factor of feed rate isdetermined by grinding force ratio, and force deviation and its change rate are used as evaluationindexes. Thus, adaptive control of constant force in grinding process is accomplished. Simulationand tool grinding test indicate that the system has high precision and stability, and reduces cuttererror efficiently
