Formation Mechanism of Ground Surface Profile under Considering Grinding Wheel Surface Topography

Abstract

This report deals with experimental analyses on the formation mechanism of ground surface profile under considering wheel surface topography in plunge grinding process. Main conclu-sions are as follows : (1) Ground surface profile of workpiece can be predicted under considering spring-back of grooves, meandering phenomenon and geometrical relationship between the theoretical cutting depth of abrasive grain and the actual depth of groove. (2) The meandering of cutting groove generated by an abrasive grain is occurred in the form of a roller with small vibrations. (3) After grinding, abrasive grains with low stiffness are remained on the wheel surface and abrasive grains with high or low stiffness are mixed under the wheel surface.
