In centerless grinding, it is indispensable to provide an evaluation function of grinding conditions for the purpose of automatically selecting the optimum setup parameters by closed-loop control to minimize workpiece roundness error. In this paper, the workpiece rounding mechanism is investigated analytically. It is found that the rounding behavior can be characterized by a function called the waviness decrease rate. For the given setup parameters, the grinding conditions are evaluated by calculating the waviness decrease rate. Simulations and experiments were conducted and the results were compared to those of the calculation. It was found that the waviness decrease rate can be used as the evaluation function.
