Investigation of the Grinding Process and Infeed Control in Abrasive Belt Grinding

Abstract

In abrasive belt grinding, the elastic deformation of rubber contact wheel is the cause of residual depth of cut and the recovering of elastic deformation generates an excessive depth of cut at retraction stage. In this study, the cumulative actual depth of cut with the grinding time were measured, in plunge belt grinding. And also, the transient state of the grinding process was theoretically investigated. As a result of that, the amount of residual depth of cut and excessive depth of cut were explained in the case of varying the grinding conditions. Moreover, an infeed control was proposed to decrease the grinding time and dimensional error of workpieces. The proposed infeed control offered a basic indication of the efficient and accurate belt grinding.
