Preparation Of Electrolysis Belt And The Micro-cutting Edge Machining Simulation Of Silicon Carbide

Silicon carbide material played an important position in the field of aerospace and other cutting-edge science and technology because of its excellent characteristics. SiC work-piece accuracy requirements are getting much higher with the development and progress of science, the shape of the work-piece also getting more complex. In order to meet these requirements, new processing methods are coming.In this paper, a new electrolytic belt grinding tool was developed which can meet the requirements of complex surfaces on the theoretical basis of the electrolytic grinding wheel. Polymer electrolyte which is commonly used in lithium-ion battery was selected to be used as the electrolysis belt binding agent. Added inorganic particles into the polymer electrolyte to increase its conductivity, and verified the feasibility that polymer electrolyte used as electrolysis belt binding agent by experiment. The pulse power parameters which are appropriated to the electrolysis grinding, the amplitude, frequency, and duty cycle of pulse power have a decisive influence on the effect of electrolysis grinding. A cutting model of silicon carbide is established, and the cutting simulate parameters of SiC were set up to analyze the distribution of the residual stress that on the machined surface in the cutting process. At last, analyzed and summarized the distribution of the residual stress which can be affected by cutting speed and tool geometry parameters.The polymer electrolyte as the electrolysis belt binders, overcame the shortcomings just like fixed shape that metal binding agent possessed. So it can grind complex shape of the work-piece surface, improving cutting accuracy and efficiency. The amplitude, frequency, and duty cycle of pulse power can be adjusted within a certain range, and the mean intensity of electrolysis can be controlled through adjust the size of the different parameters. For example, the larger of the pulse duty cycle, the greater of the intensity. The result of residual stress distribution is composited to the material cutting theory, so it can provide some reference value to the actual machining.
