Simulation of Ultra-temperature Cooling on Thin Wall of Titanium Alloy
The milling of titanium alloy thin-walled parts can be subject to a great deal of processing load,and the temperature can rapidly ascend due to the combination of force and heat. Therefore,liquid nitrogen is applied as a cooling medium in this process. A finite element simulation model of the milling process by ABAQUS software is used to investigate the influence of temperature on the deformation of titanium alloy thin-walled parts. Variation in the deformation of workpiec-es with varying milling parameters is determined by setting 20 ℃ and-196 ℃. After the data obtained from the two are compared and analyzed to obtain the research results. In conclusion,low temperature can reduce the deformation of the workpiece compared to normal temperature during the milling process of titanium alloy thin-walled parts. Thus,low tempera-ture is beneficial for this purpose.
