Chapter 1 Introduction Definition of Manufacturing Machining Technology Definition of Manufacturing ØWhat is manufacturing? Manufacturing is more than transformation of raw materials into value-added outputs meeting specifications. ØDefinition[1]: Manufacturing is a series of interrelated activities and operations involving design, material selection, planning, production, quality assurance, management, and marketing of discrete consumer and durable goods. ØTwo broad categories of present-day manufacturing activities: (1) Continuous-process production ( food industry and oil industry )
(2) Discrete-product production (motor car industry, aircraft manufacture, production of domestic equipment and the machine tool industry) In this course, the focus is on discrete-product manufacturing. Metal cutting plays a very important role in those discrete-product manufacturing systems. According to a survey, about 10% of all the metal produced is turned into chips (切屑). Machining Technology According to the last section, metal cutting(machining) is a very important operation in modern manufacturing. In ing chapters, the following topics will be introduced: ØUnderstanding the evolution of metal cutting technology ØMetal cutting operations and terminology ØMachine tools (traditional & nor traditional machining) ØAutomation of machining operations &
