FEM Simulation And Experiment Research Of Cutting Temperature And Force In Orthogonal Cutting Of Titanium Alloys

Metal cutting is a process with non-linear and heat-stress coupled.The heat is mostly from the distortion of chip and the friction at the tool-chip and tool-workpiece interface.The big heat source increases the temperature and causes the tool's abrasion.The cutting force denotes the cutting characters. The dynamic value affect the tool's abrasion and the quality of machined surface. So the research of cutting temperature and force is important.The main work is to explore the temperature's distribution in tool area, chip area, and workpiece area and the force, to visualize the chip shape. Based on the finite element theory, the author provides the FE cutting model, uses the ABAQUS/Explicit software to simulate, according to the workpiece and tool's material changing with temperature, changing the friction type, defining the chip separating law, subdividing the local parts. After the FEA the common rules between cutting temperature, force and cutting parameters are denoted. The chip shape are shown.The cutting experiments are done to denote the common cutting rules. The result from FEA is alike the experiment result and the result. The comparing result validates the veracity and feasibility of FEA.
