汽轮机,燃气轮机叶轮枞树形叶根槽的加工是难度较大的加工项目。本文通过实例,提出了改进粗拉刀具的刃齿形状,来保证精拉时刃齿各部分具有相同的加工余量,以此达到提高加工质量的目的。文中还给出了改进刀具刃齿参数的数值计算。
Turbine, gas turbine impeller fir root blade groove processing is more difficult processing projects. In this paper, an example is given to improve the edge shape of the roughing tool to ensure that each part of the edge tooth has the same machining allowance in order to improve the machining quality. The paper also gives the numerical calculation to improve the cutter blade parameters.
