Study On Cutting Performance Of Milling For High Silicon Aluminum Alloy CE11

High silicon Aluminum Alloy is a kind of new material,are widely used in automotive engine parts and electronic packaging shell,its light weight,low coefficient of thermal expansion,high strength,and must have a good market in the future.However,high silicon aluminum alloy material with high silicon content.And it has many problems in the processing cycle,tool wear,low processing efficiency and bad surface quality.Therefore,it is very important to select the optimal milling parameters and tools for the processing of high silicon aluminum alloy.In this paper,using the finite element software AdvantEdge FEM to establish high silicon Aluminum Alloy milling 3D model,using TiAlN coated carbide tool and diamond coating tools to see the milling performance.The finite element simulation of high silicon aluminum alloy was carried out by orthogonal experiment with four factors and three levels.At the same time,by using the range analysis method,the optimal processing scheme is selected,which is compared with the best processing scheme of the cemented carbide.In addition,a single variable is used to analyze the influence of the single change of each factor on the cutting force and temperature.In order to verify the results of finite element simulation,the experimental verification is performed,using piezoelectric sensors and infrared thermal sensor accurately collected on the experimental results,compared with the simulation data,the error in the controllable range,indicating that the finite element simulation can accurately reflect the actual results.At last we draw the conclusion: the Ti Al N coating tool and diamond coated tools can be very good for the actual production and processing of high silicon Aluminum Alloy;Diamond coated cutting tool processing in a low speed feed under the highest efficiency,and temperature and pressure are low;The feed and milling depth have a great influence on the milling force,while the feed and milling depth increase,and the main milling force increases obviously;With the increase of milling width,the back force increases greatly;Milling speed has little influence on cutting force;Using finite element simulation to study the cutting process quickly and accurately,greatly reduce the experimental expenditure,improve the efficiency.
