Research On Numerical Simulation Of Cutting RTCr2and Optimization Of Cutting Parameters

With the development of machining, High Speed Machining has become one of the directions of development of the machining. Since the1930s, High Speed Machining has become practical application from concept step by step. And nowadays, High Speed Machining has become one of the cores of technology in advanced manufacturing technology. Since High-speed machining has advantages of high processing efficiency, high machining accuracy, and environment-friendly processing method, it will have a good prospect of application in precision machinery manufacturing and the processing of difficult materials. In the high-speed machining, the cutting parameters have a great impact on the cutting force and cutting temperature, and cutting forces and cutting temperatures affect tool wear, work piece surface quality and machining accuracy. Therefore, to optimize the cutting parameters in the high-speed cutting is a meaningful research topic. In this paper, in order to optimize the cutting parameters in high speed cutting, high-speed cutting of cutting parameters (cutting speed, feed per tooth is the amount of the back of cut) were selected as the research object, and the cutting force was selected as criterion.In this paper, firstly, the definition of High Speed Machining was discussed. The status of domestic and foreign research, the research methods and ideas of this subject are reviewed. Secondly, this study is closely related to High Speed machining basic theory. The tool material and geometry parameters, and selected on the basis of the processed materials, material models, chip separation criteria, the friction model, contact model, the key technology must be selected based on the theory and research results. Thirdly, we use the ABAQUS finite element analysis software to establish the three-dimensional cutting finite element model and to simulate the High Speed Cutting process. Synchronization, high-speed cutting tests, cutting the amount of high-speed cutting experiments as far as possible consistent with the cutting parameters of the simulation process, whether it is reasonable to verify the simulation results. The simulation results and experimental results were analyzed. Based on the experimental data, we use the Taguchi method to optimize the cutting parameters.Through the research of this subject, we not only obtain a more reasonable RTCr2alloy cast iron materials finite element model, but also obtain the optimization cutting parameters for High Speed Cutting RTCr2alloy cast iron material with carbide cutting tool. I hope that the research of this subject can provide a reference for High Speed Cutting.
