摘　　要：汽轮机叶片型面是较复杂的曲面体零件,针对加工时一般采用比较保守的进给速度而导致生产效率不高,提出了对于材料选择方钢的汽轮机叶片型面加工进给速度优化思想。在对叶片型面粗加工及半精加工进给速度优化原理分析基础上,提出了恒定材料去除率粗加工和恒定切削厚度半精加工优化策略。实验结果证明,基于恒材料去除率和恒定切削厚度优化叶片型面加工,效果明显,加工效率大大提高,节约了成本。The steam turbine blade moulding surface is a quite complex kind of curved surface parts. Aimed at the problem of quite low production efficiency, due to the conservative cutting feed rate generally adopted in the processing, the idea of optimizing the cutting feed rate of the steam turbine blade moulding surface made from square steel of selected material was come up. Based on the a- nalysis of cutting feed rate optimization principles during the rough machining and semi-finishing of the steam turbine blade moulding surface, it was proposed of two optimization strategies, i. e., the constant material removal rate rough machining strategy and the con- stant thickness cutting semi-finishing strategy. The experimental result proves that based on the constant material removal rate rough ma- chining strategy and the constant thickness cutting strategy, the effects are obvious, the production efficiency is highly improved and the cost is also reduced.
