Finite Element Simulation and Experiment Study of High Manganese Steel Drilling

Around the simulation and experiment of the drilling process of the high manganese steel, the method to set up model and relevant theories has been studied in simulation course. Utilize plastic forming finite element software, material model of high manganese steel and geometric model have been built. The drilling processing of the high manganese steel has been simulated, continuous chip and the data of drilling thrust has been got. Simulation result shows that the increase of feed results in the increasing of drilling thrust and the increase of cutting speed insults in the decreasing of the drilling thrust. The maximum temperature district of the cutter is close to cutting edge sharp more; it makes the cutter easier to wear and tear. Meanwhile, the experiment research on the high manganese steel drilling has been also carried on. Experimental result and simulation result are relatively consistent, shapes of chip that the experiment and simulation obtains are extremely similar, thus the exactness of simulation models set up has verified.
