第一节概述在现代化的制造工业中,机械产品的生产过程大致可分为三个阶段:即产品的决策阶段、设计与研究阶段和制造阶段。产品的制造阶段即是把原材料转变为产品的过程,在这一过程中毛坯制造、机械加工、热处理、装配等直接改变毛坯或零件的形状尺寸、材料性能的过程称为生产工艺过程或工艺过程。生产工艺过程中的机械加工、装配调试等称为机械制造(工艺)过程。这一
Section I Overview In the modern manufacturing industry, the production process of mechanical products can be divided into three stages: the product decision-making stage, design and research stage and manufacturing stage. The manufacturing stage of the product is the process of converting the raw material into the product. During this process, the process of manufacturing the blank, machining, heat treatment, assembling and the like directly changes the shape and size of the blank or the part and the material performance is called the production process or the process . Production process in the machining, assembly and commissioning, known as mechanical manufacturing (process) process. This one
