建立了钛合金-石蜡系统静力学模型,从静力学角度研究钛合金薄壁框类零件在瞬态切削力作用下工件的受力特点和变形情况;设计石蜡填充钛合金框类薄壁件铣削试验,对试验过程中的振动加速度信号和已加工表面质量进行分析对比,并研究石蜡辅助加固对钛合金薄壁件加工性能改善的作用机理。研究表明:采用石蜡辅助加固能可显著降低钛合金薄壁件加工让刀变形,提高切削加工稳定性,改善加工表面质量、

The static model of titanium-paraffin system is established. Based on the static analysis, me- chanical and deformation characteristics of the thin-walled component are stndied under transient force. Milling experiments with and without paraffin reinforcement are conducted. The acceleration signals in the milling process are measured and analyzed. The surface roughness of the finished part is also investigated. It is showed that paraffin reinforcement milling thin-walled component can reduce part deflection, improve the machining stability and sur- face finish significantly.
