  2. Overview • Computer Aided Manufacturing Defined • Brainstorming Exercise • Nuts and Bolts • How It Works • A Real World Example • Summary of Presentation • Works Cited

  3. Computer Aided Manufacturing • 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. • (Russell, Taylor 213)

  4. Computer Aided Manufacturing • Other definitions: • “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.” • (techtarget.com)

  5. Computer Aided Manufacturing • Using technology to produce • Leveraging capital investments • Increasing productivity through automation • Decreasing lead time through programmatically controlled machinery

  6. Brainstorming Exercise • How can CAM benefit your company? • Integrate design and manufacturing • Make mass customization possible • Reduce costs • Leverage computing power • Automate manufacturing processes

  7. Brainstorming Exercise • Identify benefits and costs of CAM: • Direct Benefits • Indirect Benefits • Tangible Costs • Intangible Costs

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

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

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

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

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

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

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

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

  16. How It Works • Old System (without CAM) • Product 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 • New System (using CAM) • Product 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 • C D Ward and Associates • Manufacturer of knitwear in England • Needed to automate design-to-manufacture process

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

  21. Summary • Here’s what we’ve looked at so far…. • Definition • Brainstormed • Nuts and Bolts • How It Works • Real World Example

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

  23. Works Cited • Russell, Roberta and Taylor, Bernard. Operations Management. 3rd ed.
