Simulation analysis of workpiece thermal deformation during cylindrical plunge grinding

-Estimation of temperature distribution in workpiece from electric power used for grinding-

Abstract

Thermal deformation of workpiece due to grinding heat reduces the dimensional accuracy. In order to estimate the worpiece thermal deformation, it is necessary to understand the temperature distribution in workpiece. In this study, simulation analysis of temperature distribution in workpiece calculated from readily-measurable grinding power is newly proposed. In this analysis, grinding power is estimated from measured electric power of motor that rotates grinding wheel. Grinding force is calculated from estimated grinding power. The grinding heat transferred to workpiece is calculated from estimated grinding energy and temperature distribution in workpiece is analyzed.
