回顾了建国以来大连机车车辆厂工艺工作的曲折发展过程和丰硕成果。介绍了目前工厂的工艺技术水平和工艺管理体制。工艺技术随产品的产生而产生,随生产的发展而发展。工厂的生产发展经历了从修车到造车,从造蒸汽机车到造内燃机车,从单一产品到多种产品,从国内到国外的几个大的发展阶段,工艺技术工作也相应地从无到有,从小到大,从集中到分散,又从分散到集中,从技术落后到实现工艺技术工作的规范化、程序化和统一化的先进水平。还介绍了工厂柴油机零部件制造工艺、热处理工艺和数控技术、组合夹具、刀具等工艺技术的发展和进步 Reviewing the tortuous development process and fruitful results of the craft work of Dalian Rolling Stock Works since the founding of the People’s Republic of China. Introduced the current factory technology and process management system. Technology with the production of products produced, with the development of production and development. The factory’s production development has gone from repairing cars to making cars, from making steam locomotives to making diesel locomotives, from single products to multiple products, and from several big stages of development both at home and abroad. From there, from small to large, from concentration to dispersion, and from dispersion to concentration, from technological backwardness to the standardization, proceduralization and standardization of the process of technological work. Also introduced the factory diesel engine parts manufacturing process, heat treatment technology and numerical control technology, combination of fixtures, tools and other process technology development and progress
