N2 - This paper deals with an evaluation method of grinding conditions in centerless grinding. It is difficult to optimize the grinding conditions for minimizing the workpiece roundness error because there are lots of process parameters such as center height angle, blade angle and stock removal rate. We had proposed the waviness decrease rate as an evaluation function of grinding conditions to select the optimum process parameters automatically. To build the closed-loop control system for the process parameters, however, it is necessary to find a practical way to measure the waviness decrease rate. In this paper, the relationship between the waviness decrease rate and the dynamic components of grinding force was investigated analytically. It was found that the frequency characteristic of the waviness decrease rate shows a similar tendency to that of the dynamic components of grinding force. Grinding force measurement system was built and measurement and evaluation of the grinding force were carried out. As a result, it was confirmed that the grinding conditions can be evaluated using the dynamic components of grinding force.
