Effects of Milling Process Parameters on Cutting Temperature of MG-Li Alloy Parts Based on Frozen Loading Card and Simulation Verification
In this paper,the effects of freezing loading on reducing the temperature of MG-Li alloy shell with dif-ferent milling parameters were studied.The milling experiment of MG-Li alloy shell was carried out by means of ice plate and infrared thermometer,and the influence of ice loading method on the temperature of MG-Li alloy shell parts and cutting tools was explored.The results show that the spindle speed n ranges from 3000 to 3500r/min and the back cutting capacity ap ranges from 0.3 to 0.7mm.In the process parameter range of 300～550mm/min,the freezing loading method can effectively control the machining parts of magnesium lithium alloy shell parts and the temperature of the cutting tool,so that the cutting process temperature of magnesium lithium alloy shell parts and the tool temperature are far lower than the burning point temperature,significantly avoiding the safety risks of combustion during the processing process,and greatly improving the processing efficiency.The process method has been successfully applied in the con-trol shell of a satellite gyroscope.
