Research On High-speed Turning 3Cr13 Stainless Steel Cutting Force And Surface Roughness

With the rapid development of science and technology, lots of advanced industrial countries pay more and more attention to high cutting efficiency and high surface quality as the main feature of the high-speed cutting technology,which have brought good economic for the enterprise and the countries. Because 3Cr13 is a carbon martensitic stainless steel, the material is relatively wide range of applications and its processing technology research involving relatively narrow,especially the research of cutting tool angle and considering influence of cutting parameters on cutting force and surface quality of machining in the high-speed, generally processed in the ordinary cutting speed, due to the processing at normal speed, resulting in cutting resistance is relatively large, and different quality, manufacture efficiency is relatively low. With the development of high speed machine tools and cutting tool, high speed cutting machining by way of 3Cr13 stainless steel is possible, therefore, research on the processing of 3Cr13 high speed cutting stainless steel become meaningful.Firstly, the application-specific cutting Advant Edge FEM software to simulate high-speed turning process 3Cr13 by orthogonal experimental design and range analysis method to optimize the results, which reach a feed rate, the cutting depth, the cutting speed, tool rake angle the optimum combination, according to this combination to guide experiments; Then through the single factor experiment and orthogonal experimental design of high speed cutting of 3Cr13 stainless steel, research the relationship of process parameters on cutting force and surface roughness, and to establish the appropriate model; Finally, through the response surface method to optimize the the surface roughness, to obtain the results in case of a low surface roughness of the process parameters’ s optimum combination.(1) Through the Advant Edge FEM cutting software to simulate the machining processing high-speed cutting 3Cr13 material. using orthogonal experimental design and range analysis, the minimum cutting force as the goal, it is concluded the optimal combination of feed rate, depth of cut, cutting speed and tool rake angle, and use it to guide the experiment, designed to ensure that under the condition of cutting force is small, the process parameters combination of minimum surface roughness is obtained.(2) Through single factor and orthogonal experimental design, processing at high speed turning 3Cr13 material by Kister dynamometer software to measure, analyze the influence of various process parameters on the cutting force and cutting force to obtain a mathematical model.(3) Through single factor and orthogonal experimental design, processing at high speed turning 3Cr13 materials on behalf of the surface roughness by Marh3 instruments to measure, analyze the impact of various processing parameters on surface roughness and surface roughness derived mathematical model(4) Through the response surface method to optimize the the surface roughness, within the constraints of other factors, obtain the optimum combination of feed rate, depth of cut, cutting speed and tool rake angle, in the high-speed turning 3Cr13 stainless steel, in order to obtain a surface roughness value in the lower range of the optimum combination of parameters for the feed rate f=0.12mm/r, the depth of cut ap=0.42 mm, the cutting speed vc=621m/min, tool rake angle γ0=17°50",to improve the actual mechanism of 3Cr13 material processed.
