Effects of Grinding Parameters on Surface Quality in High-Speed Grinding Considering Maximum Undeformed Chip Thickness

Grinding is a precision machining process that is widely used to achieve good surface integrity and inish. In order to study and reveal the influence of grinding process parameters such as grinding depth, feed speed, and wheel linear speed on the surface quality of the slider raceway, a series of single-factor grinding experiments under different grinding parameters are carried out on high-speed precision surface grinding machine in this research. 3D surface profiles of the slider raceway are obtained after the grinding experiments. An image processing method is employed to evaluate the surface quality of slider raceway by surface roughness, height distribution function, skewness, and kurtosis. Vibrations of spindle and workpiece, maximum undeformed chip thickness (MUCT), and grinding force are taken into consideration to reveal the correlation between grinding parameters and surface quality. The results indicate that increasing the grinding depth, wheel speed, and feed speed will all lead to an increase in the surface roughness of the slider raceway to some extent. The study finds that wheel speed and feed speed are the more significant factors affecting the surface quality than grinding depth. It is also revealed that grinding parameters and vibrations together affect material removal and surface quality during grinding.
