摘要
针对钛合金磨削加工困难的特点,系统开展了TC4钛合金高效深磨工艺试验.通过对单位面积磨削力F'随最大未变形切屑厚度hmax和当量磨削层厚度aeq的变化情况和特征进行分析,探讨了其材料去除方式的变化,研究了TC4钛合金高效深磨过程中消耗的磨削功率.为寻求适合钛合金高效深磨的工艺及方法,提高钛合金加工质量和效率打下坚实的理论基础.
Focusing on the characteristic of hard-to-grinding for titanium alloy, systemic process experiments was done about grinding TC4 titanium alloy under the high efficiency deep grinding condition. Based on the analysis to the changing and characteristic of unit area grinding force F＇ with maximum undeformed chip thickness hmax and equivlent cutting thickness αeq, this paper discussed the changing of its material removal mode and analyzed the changing and characteristic of grinding force ratio N, specific grinding energy es with corresponding parameters further. Then, it was analyzed about the consumption of grinding power on the process of high efficiency deep grinding for TC4 titanium alloy.
