Influence of Control Wheel Velocity and CENTER Height Angle of Workpiece on Roughness and Roundness Error in Plunge Centerless Grinding

This paper presents the research on the influence of control wheel velocity and center height angle of workpiece on quality of workpiece when grinding 20Cr - carbon infiltration steel uses plunge centerless grinding process. Two parameters of quality of workpiece which are considered in this paper are roughness (Ra) and roundness error (∆). Then the influence of control wheel velocity and center height angle of workpiece on roughness and roundness error is shown. Also, this work points out the logical ranges of control wheel velocity and center height angle of workpiece when grinding 20Cr - carbon infiltration steel uses plunge centerless grinding process. Finally, suggestions for further research are given
