Wheel Working Surface Topography and Grinding Force Distributions in Creep Feed Grinding

摘要

This paper discusses the topographic features of wheel working surfaces and the grinding force distributions in wheel-work contact zones of creep feed grinding. Grain cutting edge wear is observed by a Scanning Electron Microscope (SEM) and quantitatively evaluated in terms of attritious wear flat percentage, which is able to characterize the wear behavior. By measuring the normal and tangential grinding force distribution in the grinding zone, the distribution form of grinding forces can be approximated to be triangular and the grinding forces increased rapidly due to workpiece burn. It is shown that the variation of the grinding force and the distribution are closely related to cutting edge wear characteristics.
