Research and simulation of the machining process of difficult-to-cut materials

Heat-resistant and high-alloy steels and alloys are difficult materials to machine. Optimizing the cutting parameters for such materials is a complex and multi-factorial technological process planning task. The paper describes the method of analysis of loading, thermodynamic and stress-strain state of a workpiece while cutting of typical representative of hard-to-cut materials (chromium-nickel alloy IN718) using finite element simulation. Influence of feed rate on cutting force and temperature in the zone of chip formation is given.

Research of the Tool Wear Process by Finite Element Method

The paper studied the wear process, as all mechanical cutting process is accompanied by this phenomenon. The process of wear is a complex phenomenon and is of interest to model the process and increase understanding of the wear of cutting tools. This paper presented a model that is considered most appropriate to the experimental parameters, this wear by Usui. This model describes the rate and amount of wear on the tool depending on cutting parameters.
