Abstract

Grinding is an important means to guarantee the quality of the machined surface, however, the interaction between machine and grinding process causes poor surface quality. Focusing on face grinding, the influence of process-machine interaction on ground surface was analyzed based on the investigation of surface topography simulation. A visual wheel topology was simulated based on the random nature of grains located on the wheel surface. The grain trajectory equation and workpiece topography equation were established based on the analyses of interference between grains and workpiece. The interaction between grinding process and spindle-wheel was modeled considering the inverse influence of wheel deformation on process and simulated by adopting a coupling simulation method. Taking the process-machine interaction into account, a novel simulation model for surface topography of the grinding process was proposed. Grinding test verifies the accuracy and effectiveness of the given algorithm. The method can be further used to optimize the grinding process parameters.
