Creep-feed grinding is an abrasive machining process, but beyond that, it doesn't resemble other forms of grinding. Nelson Beaulieu, grinding product manager with Hardinge Inc., says it makes more sense to characterize creep-feed grinding as a milling process. After all, creep-feed grinding employs a deep cut and a high metal removal rate ...

One of the most important characteristics of the creep feed grinding process is a change to the process sequence. In a traditional grinding operation, the part is sent away for heat treatment and then brought back to the shop to continue operations like grinding. This is the standard way to produce parts for manufacturers.

Abstract. The aim of our article is to propose a model of simulation of the dynamic behaviour of the creep feed grinding process. Specifically, we seek to predict the waviness of the bonded surface (depth of cut). We propose, initially, a mechanical modelling taking account of the operational parameters and the geometrical and mechanical ...
