Whats the complete form of CAM? Can you say something about CAM?2. Robots are not easily separated from CAM. What tasks can

4、they handle in industrial automation?Reading AUnit 4ProductionComputer-Aided Manufacturing Computer-Aided Manufacturing (CAM) can be defined as the use of computer systems to plan, manage, and control the operations of a manufacturing plant through either direct or indirect computer interface with t

5、he plants production resources. CAM functions center around four main areas : numerical control, process planning, robotics, and factory management.Reading AUnit 4ProductionNumerical Control (NC) Numerical control uses coded information to control machine tool movements. In modern CNC systems, end-t

6、o-end component design is highly automated using CAM programs. The programs produce a computer file that is interpreted to extract the commands needed to operate a particular machine, and then loaded into the CNC machines for production.Reading AUnit 4ProductionProcess Planning Process planning is i

7、nvolved with the detailed sequence of production steps from start to finish. Essentially, the process plan describes the state of the workplace at each workstation. The useof computers as an aid to process planning is comparatively recent and has led to a rebirth of what is known as group technology

8、 (GT). Group technology is based on organizing all similar parts into families to allow standardization of manufacturing steps.Reading AUnit 4Production Currently a process planning system is under development and it is able to produce process plans directly from the geometric model database with al

9、most no human assistance. In this system, the process planner would review the impact from the design engineer via communication and then enter this input into the CAM system which would generate a complete set of process plans automatically.Reading AUnit 4ProductionRobotics Many advances are being

10、made to integrate robotics into CAM. One of these ef forts is the US Air Force Integrated Computer-AidedManufacturing (ICAM) project, of which the goal is to organize every step of manufacturing around computer automation. As part of this program, a robot is used to drill sheet metal aircraft parts.

11、 The robot drills a set of holes to 0.005 in tolerance, and machines the perimeter of any one of 250 types of parts. Production rates are four times faster than conventional manual manufacturing.Reading AUnit 4ProductionFactory Management This portion of CAM ties together the other areas to coordina

12、te operations of an entire factory.The management system relies heavily on group technology with its families of similar parts. Computers also perform various management tasks such as inventory control and material requirements planning (MRP) systems.Reading AUnit 4Productiongeometric modelgroup tec

What is the manufacturing process controlled by in a CAM system? 5. What are the advantages of CAM mentioned in the talk? Please note down one of them.Unit 4Produ

49、ctionComputer. CAM raises the production rates; allows a company to get the best from workers by increasing their productivity; makes the process planner receive the impact from the design engineer via communication;helps coordinate operations of an entire factory.ListeningUnit 4Productionv ScriptJe

50、ssica: Mr. Johnson, I learned that CAD and CAM are widely applied in mold design and mold making. Can you tell me something more about them?Andrew: Sure. CAD is the use of computer technology for the design of objects. And CAM is a system of using computer technology to assist the manufacturing proc

51、ess.Jessica: Then how are these two systems related?Andrew: CAM is commonly linked to CAD systems. The integrated CAD/CAM system takes the computer design and puts it directly into the manufacturing system; the design is then turned into many computer-controlled processes, such as drilling.Jessica:

52、CAM is one of the most dramatic changes in the manufacturing process since the Industrial Revolution, isnt it?Andrew: Exactly.ListeningUnit 4ProductionJessica: And I also knew there are four main areas of CAM. But I dont remember what they are exactly.Andrew: You mean numerical control, process plan

53、ning, robotics, and factory management?Jessica: Yes, thats right! Could you please tell me more about them?Andrew: Definitely! All these systems are concerned with a highly automated factory. Because each of the manufacturing processes in a CAM system is computer controlled, a high degree of precisi

54、on can be achieved, which is impossible with manual manufacturing.Jessica: So CAM can raise the production rates?Andrew: Yes. It allows a company to get the best from workers by increasing their productivity. It also has many other advantages.Jessica: For example?Andrew: CAM allows the process plann

55、er to receive the impact from the design Engineer via communication. It helps coordinate operations of an entire factory.Jessica: That sounds great! Thank you so much, Mr. Johnson.
