this ppt will gives u the information of automation in cad cam

1. CAD/CAM TOPIC:AUTOMATION BY J KUMAR CHANDRA Assistant professor, Department of ME, NNRG HYD

2. WHAT IS AUTOMATION? Automation is technology concerned with the application of complex mechanical, electrical, electronic , hydraulic, pneumatic or computer based system in the operation and control of production

3. Need of Automation Increased Productivity High Cost of Labour Labour Shortage Trend of labour towards the service sector Safety Improved Product Quality Reduced Manufacturing Lean Time High Cost of not Automating

4. Machines Used in Automation  Numerically Controlled Machine  Machining Centers  Robots  Automated Quality Control Inspection  Automated Identification System  Automated Process Controls

5. Types of Automation Continuous process Mass production Batch production Job production industries

6. Continuous flow process industries Continuous dedicated production of large amounts of bulk product. Examples include continuous chemical plants and oil refineries

7. Continuous process industries Sugar industry, chemical industry etc.

8. Mass production industries – Automobiles, Consumer goods etc Dedicated production of large quantities of one product (with perhaps limited model variations). Examples include automobiles, appliances, and engine blocks.

10. Batch production industries – machines, aircrafts etc Production of medium lot sizes of the same product or component. The lots may be produced once or repeated periodically. Examples include books, clothing, and certain industrial machinery

11. Batch production industries – machines, aircrafts etc

12. Job production industries – Prototypes, heat exchangers , chemical reactors etc Production of low quantities, often one of a kind, of specialized products. The products are often customized and technologically complex. Examples include prototypes, aircraft, machine tools, and other equipment.

14. COMPARISION

15. Automation is focused on reducing unit production time and to some extent time associated with planning and setting up for each batch of production. CAD/CAM is focused on reducing time for designing the product and all other activities which are accomplished once for each product and time associated with planning and setting up for each batch of production

16. Advantages Increased Productivity Reduced Overall Production time Less floor Space Required Increased overall profits of the manufacturing concern Human fatigue is greatly minimized

17. Disadvantages Technology Limits Unpredictable Development cost Initial cost are Relatively High
