摘要
在钛合金薄壁件铣削过程中,由于热—力耦合作用导致加工负载大、升温快,因此将液氮作为冷却介质应用于钛合金薄壁件的铣削。为了探究不同温度下钛合金薄壁件铣削变形的特性,基于ABAQUS软件建立有限元仿真模型,并将温度设定为20℃和-196℃,观察不同铣削参数下工件变形量的变化情况,将两种数据进行对比分析。研究结果表明:钛合金薄壁件在铣削过程中,相较于常温,低温可以减小工件的变形量。由此可得,低温可以优化钛合金薄壁件铣削的加工过程。
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 workpieces 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 temperature is beneficial for this purpose.
