Investigation of Undeformed Chip Thickness Model and Surface Roughness Prediction in Belt Grinding

Abstract

Abstract Undeformed chip thickness plays a very important role in studying the materials remove mechanism in flexible belt grinding and predicting ground surface roughness. A calculation model that can be used to effectively predict the undeformed chip thickness in flexible belt grinding is established based on the height distribution of abrasive grains. It can lay the foundation for in-depth study of belt grinding mechanism. In this model, the real contact arc length is derived based on the elastic deformation of the contact area between the abrasive belt and workpiece. The real depth of cut prediction model is introduced considering the belt grinding processing characteristics. Based on the established undeformed chip thickness model, a ground surface roughness calculation model is further reached, and a series of verification experiments are carried out. The results show that the predicted value and the measured value have the same trend basically under different grinding process parameters. The error of the predicted value is mostly distributed between 5% and 16%, which proved the reliability of the developed models preliminary.
