重型机械属单件小批生产,其特点是:另件重、尺寸大,重复制造机率少,制造周期长。根据这些特点,作者提出了设计工艺需遵循的几项基本原则。考虑到它对提高管理水平,发挥与挖掘生产能力,有一定参考作用,故删节摘登其主要论点。 Heavy machinery is a single batch of small batch production, its characteristics are: another piece of heavy, large size, repeated production of less chance, long manufacturing cycle. Based on these characteristics, the author proposes several basic principles that the design process must follow. Considering that it has a certain reference role in improving the management level and exerting and excavating the production capacity, the abridgement of its main arguments has been made.
