For superalloy GH4169poor processing, tool wear serious, affecting the surface quality of the workpiece and other issues, using the finite element software AdvantEdge to simulate the formation process of superalloy GH4169 chip in two-dimensional, and researching the characterization of serrated chip. Take the single factor experiment and conduct finite element simulation for superalloy GH4169 in changing the rake angle and tip arc radius of the situation. The simulation and the chip shape taking from experiments will be compared to prove the feasibility of the simulation. And find out changes of rake angle and tiparc radius; make clear the influence of degree of serrated chip. The results show: with the rake angle increases, serrated degree increases, and with tiparc radius increases, serrated degree increases. The study provides a reference for reasonable choice of optimized cutting tool geometric parameters.
