| 目的 探究钛合金清洁切削过程中能量消耗的变化与加工表面完整性的关系，通过切削参数优化选择，以实现加工表面质量的控制，从而提高钛合金高效洁净制造零件的使用寿命和服役性能。方法 本文提出一种基于能量消耗的过程签名方法，来描述多工步清洁切削加工过程与加工表面完整性的相互影响。建立了净切削比能计算模型，结合钛合金两工步铣削试验，分析了粗加工参数变化对粗加工、精加工切削力，以及净切削比能的影响规律，并进一步对两工步加工过程中的净切削比能展开研究。本文研究了不同粗加工参数条件下粗加工和精加工表面残余应力及微晶尺寸的变化规律。结果 切削力和切削参数的变化均会影响净切削比能的大小。多工步切削加工过程中，粗加工和精加工切削参数的不同会改变净切削比能，进而引起表面完整性的变化。对切削比能影响最大的是径向切深，其次是进给量、切削速度。随着进给量和径向切深的增大，切削比能降低;随着切削速度的升高，净切削比能先增大后减小。净切削比能较大时，加工表面层残余应力较大，微晶尺寸较小。结论 在保证加工质量的前提下，从节能降耗的角度出发，选取合适的切削速度、较大的切削深度、进给量，从而降低净切削比能、减少能量消耗，提高加工表面完整性。 |
