Abstract
This contribution at the study of the dynamic behavior of the Creep Feed Grinding Process is focused on of the influence of the machining parameters (geometric forms, surface quality …) the environment. After a concise bibliographic study, many simulations are realized in the environment of the Danobat (LGB) Grinding machine, in order to evaluate the stability of the system by exploiting the stability lobes. The evaluation of the stability of system POM is analyzed according to each parameter (mass, stiffness and ratio damping) retained for this study. The aim of our study consists to propose a simulation model of the dynamic behavior of the creep feed grinding process. Specifically, we seek to predict the undulation of the bonded surface (depth of cut). We propose, initially, a mechanical modeling taking account of the operational parameters and the geometrical and mechanical characteristics of the workpiece, the tool and the machine-tool structure. The models are founded on the Newton’s second law and the Work Energy principles with various assumptions on the contact wheel workpiece. In a second time, computer simulations (Simulink) are proposed according to an experience plan (5 factors on 2 levels) in order to evaluate the undulation of the profile thus that the stability and the precision of these models.
