Formation of a model of rheological properties of hard-to-machine materials in the process of intensive cutting force deflection

Abstract

Improving the efficiency of high-speed machining (HSM) requires in-depth study of the physical phenomena accompanying the cutting process. The main difference between HSM and traditional machining in terms of physics is the prevalence of swift dynamic processes both in the cutting zone and in the “machine - fixture - tool – product” system, as well as marked nonlinearity of the laws of development of these processes. In this regard, the study of physical phenomena accompanying the process of HSM, and the establishment of their relationship with the stability of the cutting process and the quality of the machined surface is an urgent task. This article describes a procedure of determining the parameters of the rheological properties of the titanium alloy BT6 material used in aircraft engine construction, in face milling. The calculations were performed in the CAE system Deform using a FEM-model.
