一、概述我厂从一九七九年起,开展了叶片型面计算机辅助制造的研究工作,已初步获得成功。就此加以介绍。传统的叶片制造过程是:先根据叶片设计图纸给出的叶型各截面型值点,设计制造一批型面样板,根据这些样板用钳工方法制造叶片锻模及标准型面块(靠模),然后将模锻出的毛料用靠模法进行加工(如靠模铣、砂带磨和电解加工等)。这种方法的缺点是:1.生产准备劳动量大,周期长。2.毛料精度低。采用计算机辅助制造后就可以大大缩短生 I. Overview Our factory has conducted initial research on computer-aided manufacturing of blade profiles since 1979. Introduce this. The traditional blade manufacturing process is to design and manufacture a batch of prototypes according to the leaf shape points given by the blade design drawings and to manufacture the blade forging dies and the standard type of surface block by the fitter method according to these samples. , And then forging the wool by the mold method for processing (such as by mold milling, belt grinding and electrolytic processing, etc.). The shortcomings of this method are: 1. Production preparation labor, long cycle. 2 wool low accuracy. Using computer-aided manufacturing can greatly reduce students
