| Exercise 9. Make up your own sentences according to the models.
Model A : They designed that model. They did not use the computer. They designed that model without using the computer. 1. They assembled the car parts. They did not use FMS. 2. They improved the processes. They did not increase the price. 3. They performed different operations. They did not make production more flexible. 4. They controlled the production. They did not apply incredibly complex software. 5. They tried to attach doors to the car. They did not use special equipment. Model B: When they introduced wide scale automation, independent automation processes began to develop. On introducing wide scale automation, independent automation pro- cesses began to develop. 1. When we came to the plant, we installed new machinery. 2. When they returned to the workshop, they installed the necessary equipment. 3. When the idea of FMS was proposed, computerized numerical controls succeeded in bringing a controlled environment to the factory floor. 4. When they started to use FMS, they increased the number of units produced per hour. 5. When they completed the manufacturing, they faced many problems. READING Exercise 10. Read the text, try to focus on its essential facts and choose the most suitable heading given below for each paragraph. 1) FMS Is an Automated Production System 2) Early FMSs 3) Modern FMSs 4) Generic FMS Components FLEXIBLE MANUFACTURING SYSTEM Flexible Manufacturing System (FMS) is famous for being both a manu- facturing technology and a philosophy. “System” is the key word for a flex- ible manufacturing system. FMS incorporates a system view of manufac- turing. The FMS idea was proposed in England (1960s) under the name “System 24”. It was a flexible machining system that could operate with- out human operators 24 hours a day but being controlled by a computer. 92 The concept of flexible manufacturing systems went on evolving at that time when robots, programmable controllers, and computerized numerical con- trols succeeded in bringing a controlled environment to the factory floor in the form of numerically-controlled and direct-numerically-controlled ma- chines. Early FMSs were large and very complex, consisting of dozens of Computer Numerical Controlled machines (CNC) and sophisticated mate- rial-handling systems. They were too expensive and they were controlled by incredibly complex software. Currently, the trend in FMS is towards small versions of the traditional FMS, called flexible manufacturing cells (FMC). Today two or more CNC machines are considered a flexible cell and two or more cells — a flexible man- ufacturing system. The progress of computing machines allowed to introduce a wide scale automation of all branches of industry and led to independent development of automation processes: — Automated Data Processing: the appearance of Automated Control Systems and Computer-Aided Designing (CAD); — Automation of Production Technology: the appearance of Numerical- ly-Controlled Equipment, Computer-Aided Manufacturing (CAM) and In- dustrial Robots. Thus, a flexible manufacturing system is a group of numerically-controlled machine tools, interconnected by a central control system. The various cells for machining are interconnected via loading and unloading stations by an automat- ed transport system. Simply defined, it is an automated production system that produces one or more families of parts in a flexible manner. Today, this prospect of automation and flexibility presents the possibility of producing non-standard жүктеу/скачать 4,38 Mb. Достарыңызбен бөлісу:
