Finite Element Method Simulation of Machining of AISI 1045 Steel With A Round Edge Cutting Tool
نویسنده
چکیده
In this paper, FEM modeling and simulation of orthogonal cutting of AISI 1045 steel is studied by using dynamics explicit Arbirary Lagrangian Eulerian method. The simulation model utilizes the advantages offered by ALE method in simulating plastic flow around the round edge of the cutting tool and eliminates the need for chip separation criteria. JohnsonCook work material model is used for elastic plastic work deformations. A methodology developed to determine friction characteristics from orthogonal cutting tests is also utilized for chip-tool interfacial friction modeling. The simulation results include predicted chip formation as well as temperature and stress distributions. These results are highly essential in predicting machining induced residual stresses and other properties on the machined surface.

Cutting processes can be used in batch production of polygonal bars with special features. In this paper, a new form of broaching process for cutting of hexagonal bars from raw round bars is discussed. Due to lack of rolled or drawn raw material, the final product is made of AISI 316L stainless steel bars having appropriate initial size. In this method, a fixed die is used as a tool, and by app...
