3. Computer Aided Manufacturing b What is Computer Aided Manufacturing? If is “control of the manufacturing process by computers” involving the integration of CAD engineering data and the computerized equipment which manufactures the product.If is “control of the manufacturing process by computers” involving the integration of CAD engineering data and the computerized equipment which manufactures the product. –(Russell, Taylor 213)

4. Computer Aided Manufacturing b Other definitions: “Computer aided manufacturing concerns the use of algorithms for planning and controlling fabrication processes.”“Computer aided manufacturing concerns the use of algorithms for planning and controlling fabrication processes.” –(utwente.nl) Computer aided manufacturing is “the use of computers for managing manufacturing processes.”Computer aided manufacturing is “the use of computers for managing manufacturing processes.” –(techtarget.com)

7. Brainstorming Exercise b Identify benefits and costs of CAM: Direct BenefitsDirect Benefits Indirect BenefitsIndirect Benefits Tangible CostsTangible Costs Intangible CostsIntangible Costs

8. Brainstorming Exercise b What processes in your company could be more efficient through CAM?

9. Nuts and Bolts b Essentially the collection of computer technologies used in manufacturing Computer Numerical Control (CNC)Computer Numerical Control (CNC) Direct Numerical Control (DNC)Direct Numerical Control (DNC) Flexible Manufacturing System (FMS)Flexible Manufacturing System (FMS) RobotsRobots Automated material Handling SystemsAutomated material Handling Systems

10. Nuts and Bolts b Computer Numerically Controlled (CNC) Machine that is controlled by computerMachine that is controlled by computer Utilizes monitor and keyboard for operator interactionUtilizes monitor and keyboard for operator interaction Facilitates greater control over qualityFacilitates greater control over quality Allows machine to monitor the maintenance of its partsAllows machine to monitor the maintenance of its parts

11. Nuts and Bolts b Direct Numerical Control (DNC) Each machine contains own microprocessorEach machine contains own microprocessor Entire bank of machines controlled by a single central computerEntire bank of machines controlled by a single central computer If used with automated material handling, considered to be a flexible manufacturing systemIf used with automated material handling, considered to be a flexible manufacturing system

12. Nuts and Bolts b Flexible Manufacturing System (FMS) Numerous computer-controlled machines fed by automated material handling systemNumerous computer-controlled machines fed by automated material handling system Allows for broad and deep product mixAllows for broad and deep product mix Minimal setup times enable small lot sizesMinimal setup times enable small lot sizes

13. Nuts and Bolts b Robots Mechanical manipulators that can be accessed programmaticallyMechanical manipulators that can be accessed programmatically Consistent, repetitive-motion tolerantConsistent, repetitive-motion tolerant Ideal for tasks that are hazardous to humansIdeal for tasks that are hazardous to humans

14. Nuts and Bolts b Automated Materials Handling System System where raw materials are automatically fed into machinesSystem where raw materials are automatically fed into machines Examples:Examples: –Conveyor belts –Automated Guided Vehicles (AGV) –Automated Storage and Retrieval Systems (ASRS)

15. How It Works 1. Product is conceived by engineer 2. Product is designed using CAD software 3. CAD data is transferred to manufacturing machine’s memory 4. Machine uses the CAD data to produce the product, with little human intervention

16. How It Works b Old System (without CAM) Product is designed with CAD softwareProduct is designed with CAD software –Each production machine is programmed individually OR – if not automated : –Employees are trained on proper production of the product

17. How It Works b New System (using CAM) Product is designed with CAD softwareProduct is designed with CAD software –Product specifications are sent over the plant network to each machine –Machines have ‘intelligence’ to produce the products without human intervention

18. A Real World Example b C D Ward and Associates Manufacturer of knitwear in EnglandManufacturer of knitwear in England Needed to automate design-to-manufacture processNeeded to automate design-to-manufacture process

19. A Real World Example b C D War and Associates turned to CAM 3-step process:3-step process: –converting the artistic garment specification into a technical specification –using the technical specification to calculate yarn weights and manufacturing times –converting weights and times to costs – (C D Ward and Associates)

20. A Real World Example b C D Ward and Associates CAM solution:CAM solution: –Enables faster turnaround of new products –Reduces waste by using raw materials more efficiently –Generates costs based on design specifications

21. Summary b Here’s what we’ve looked at so far…. DefinitionDefinition BrainstormedBrainstormed Nuts and BoltsNuts and Bolts How It WorksHow It Works Real World ExampleReal World Example

22. Conclusion b CAM enables companies to leverage capital investment b CAM allows for cost savings that can be passed on to the final consumer b CAM utilizes human resources more efficiently to minimize labor costs
