Experimental and numerical study on surface generated mechanism of robotic belt grinding process considering the dynamic deformation of elastic contact wheel

In the robotic belt grinding process, elastic contact condition between flexible tool and workpiece is a critical issue which extremely influences surface quality of manufactured part. The existing analysis removal mechanism based on statistic but ignoring dynamic phenomenon. this paper, we discussed pressure distribution caused by non-unique depth in process. Based single grit, obtained topology groove. With coupling groove grit trajectories removing procedure, an topography model was established with consideration Robotic experiments were accomplished to validate precision model, while result showed that roughness prediction error could be confined 11.6%, meant provided higher accuracy than traditional predicting methods.
