航空发动机涡轮叶片,是高温耐热合金材料制造的。材料的加工性很差,叶片形状复杂,精度要求高,在加工中系统刚性对加工的准确度、生产效率及工具消耗都有很大的影响。这方面的认识,我们是在二十几年从事涡轮叶片的加工中,通过正反两方而的经验逐渐建立起来的。开始,在加工中产生问题时,多从工艺方案的选定、机床精度、夹具的定位、刀具的角度等方面找原因。但大量的实践表明,很多
Aero-engine turbine blades are made of high-temperature heat resistant alloy material. The machinability of the material is poor, the shape of the blade is complicated and the precision is high, and the rigidity of the system has a great influence on the processing accuracy, production efficiency and tool consumption during processing. In this regard, we have gradually established the experience of both the positive and negative turbine blades in the processing of turbine blades in more than two decades. Initially, in the process of generating problems, the more from the selection of process options, machine precision, fixture positioning, the angle of the tool to find reasons. But a lot of practice shows that a lot
