Simulation Aalysis and Application of Aluminum Alloy Deformation Processed by 5-axis Milling Machine
To address the local deformation of aluminum alloy when machining thin wall parts of aluminum alloy motor housing of electric vehicle by five-axis milling machine,analyzes the structural characteristics of aluminum alloy electric casing,elaborates the accessibility of installing turning tools by using the conversion function of milling and turning of 5-axis machine tool to fix the spindle of the machine tool,and the application of torque motor to drive the table to rotate at high speed to transform the machining of the inner wall of the electric casing into simple turning.ANSYS finite element software was used to simulate and analyze the frictional heat generation,plastic deformation and cutting force.According to the simulation results,the turning depth parameters in nc machining programming were selected reasonably and accurately,so as to reduce the machining deformation of aluminum alloy parts and improve the five-axis machining precision,quality and efficiency of thin-walled aluminum alloy parts.
