Abstract

In cylindrical plunge grinding, the dimensional accuracy of a workpiece is reduced due to its thermal deformation. Therefore, it is necessary to simulate the thermal deformation of a workpiece during grinding in order to obtain high accuracy. To calculate the thermal deformation of a workpiece, we propose a new simulation method, in this method, the thermal deformation of a workpiece is calculated with the tangential grinding force that can be estimated easily from the measured power consumption of the wheel motor. Grinding experiments were carried out in several grinding conditions to verify the proposed method. Good agreement was achieved between the simulated thermal deformation of the workpiece and the experimental results in each grinding condition.
