Comparison of Creep Feed and Conventional Grinding
Creep feed technique is considered radically different from conventional grinding and considerable research effort has been spent to improve the process. However, there is no research work giving direct comparison of creep feed and conventional grinding based on an analysis of basic principles. This paper attempts such analysis of both processes, taking into account not only nominal removal rate but also the time lost by the necessary out-of-contact of wheel and workpiece. Experimental results provide information of workpiece quality for both processes. The effect of wheel speed has also been investigated. An attempt is made to explain the differences between creep feed and the conventional process on the basis of equilibrium of attritious and fracture wear of the wheel surface. This equilibrium depends on the conditions at wheel-work interface.
