Research On Physical Simulation And Experiment Of Cupronickel B10 In High-Speed Cutting

Compared with conventional cutting,High-speed cutting has high machining efficiency,good quality of processed surface and low machining cost and has been widely applied to aircraft industry,mold industry and maritime industry.Nonlinear process during cutting process has obstructed the development of cutting mechanism,while as the fast development of the computer simulation technology,finite element simulation technology has been applied in high-speed cutting area and has already been an important research method.This paper used finite element analysis software Third Wave AdvantEdge to simulate the process of high-speed orthogonal cutting of cupronickel B10 and analysis change law of cutting force and cutting temperature.Based on orthogonal cutting principle,a high-speed orthogonal cutting experiment was designed to obtain chip formation parameters and observe chip morphology and chip feature of cupronickel BI0 after the high-speed cutting process.Combined with Johnson Cook constitutive equation obtained from Split Hopkinson Pressure Bar experiment,constitutive model of cupronickel B10 acquired from high-speed orthogonal cutting was obtained.In the cutting software AdvantEdge,physical simulation of the two constitutive models obtained by two different methods was performed.Then compared the simulated cutting force and the simulated cutting temperature results with the results of the orthogonal eutting experiment.This paper provides a reference for high-speed eutting parameters for cutting cupronickel B10,which has important scientific significance.
