Modelling and simulation creep feed grinding process

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 characteristics of the workpiece, the tool and the machine-tools. The models are founded on the Newton’s second law and on the Work Energy principles with various assumptions on the contact wheel workpiece. In a second time, computer simulations (under Simulink) are proposed in order to evaluate the waviness of the profile and the stability and the precision of these models.
