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. – (Russell, Taylor 213)

Computer Aided Manufacturing b 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)

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

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

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

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

Nuts and Bolts b 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

Nuts and Bolts b 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

Nuts and Bolts b 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

Nuts and Bolts b 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

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

Nuts and Bolts b 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)

How It Works 1. 2. 3. 4. 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

How It Works b 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

How It Works b 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

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

A Real World Example b 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)

A Real World Example b 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

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

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
