This paper addresses a modeling method of quantitative relationships between grinding parameters and grinding results. With consideration of reasons why conventional empirical formulae are not accurate enough for practical use, a new model named the "adaptive causality model" is developed, which has adaptivity to time-varying conditions and robustness for unexpected change of conditions. As a case study, the developed model was applied to the relationship between certain dressing and grinding parameters and surface roughness of a ground workpiece, and an experimental analysis was carried out. In the experiment, wear of the edge of a single-point diamond dresser was considered as a time-varying condition. Moreover, workpieces of different material were often ground to simulate unexpected change of conditions. The experimental result proves that the "adaptive causality model" determines the quantitative relationship with sufficient accuracy in spite of change of the dresser edge and existence of some deviating data.
