    A good part of grinding operations is still dependent on skilled operators. Against such a background, this study takes up cylindrical plunge grinding, and presents a skill-formation model based on the learning process similar to that in which a grinding operator acquires skills through trial and error. The model repeats learning by giving only the total grinding stock and initial infeed rate, changing infeed rate, and evaluating the size and the removal rate in the process end. The simulation result has proved that the model shows a skill-formation process similar to that of an operator and generates desirable infeed processes.
