摘要 冲击式水轮机水斗结构复杂,型面众多,特别是在水斗内表面和根部,由于空间狭小,在走刀过程中容易发生碰撞干涉,为整体加工带来困难。传统的加工方式是采用五轴数控机床,但因价格昂贵且加工效率低,造成水斗的价格居高不下。为了降低成本和提高加工效率,提出在带有数控转台的三轴数控机床上进行整体加工,并对刀具选择、切削方式和切削参数进行分析比较,确定水斗整体加工工艺的方法。 Pelton turbine has complex structure and numerous surface, especially in bucket surface and root, because of the narrow space, they may collide and have interference, and also bring difficulties to the whole process. The traditional processing method is to use the five axis CNC machine tool, but because of its high price and low processing efficiency, the high price of pelton turbine is caused. In order to reduce the cost and improve the processing efficiency, put forward the overall processing in three axis CNC machine tools with NC rotary table, and the tool selection, cutting method and cutting parameters are analyzed and compared, processing technology for the whole bucket is developed.
