The study on a simulation model of workpiece surface topography in external cylindrical grinding

A new simulation model of workpiece surface topography in external cylindrical grinding, which is different from planar grinding discussed currently, is proposed based on reasonable assumptions. After the grinding wheel surface model is established, this simulation model in grinding is developed according to the grain trajectory mapping to workpiece when the displacement and micro-interaction between wheel and workpiece is taken to account. Finally, a contrast of surface roughness between simulation results and experiment data are performed to validate that the model in this study accords with the characteristics of external cylindrical grinding.
