CIM Applications - Quality Function Deployment
(QFD)
2

• The QFD is used in the design phase to weight
  where design engineering effort should be focused

CIM Applications - Design For Manufacturing (DFM)
3

• DFM APPLIED TO COMPONENTS
• EXPERT SYSTEMS
• Common Head Stack Assembly
• Common Disc Clamp Method
• Common tooling points
• Common Label placement
• WRITTEN GUIDES
• Example Head Stack Assembly
• Tolerance ring design minimum clearance between
  OD of bearing cartridge and Eblock bore ID to be
  .0035.
• Example Motor
• Bearing cartridge shaft and housing should be
  stainless steel

CIM Applications - Automated Storage and
Retrieval System
3

• ASRS in Finished Goods (new products)
• Single Command Cycle 18 aisle, 7 stories
• Receiving first floor
• Product lines on above floors
• Product lines use for finished goods
• Labor cost reduction
• Minimize Drive Shock from handling
• Minimize electrostatic discharge
• Control inventory for multiple customers

CIM Applications - Automated Storage and
Retrieval System
3

• Horizontal Carousel in Finished Goods (repair
  products)
• Store repaired drives
• Most frequently used close at hand
• Packaging
• Display
• with quantity
• and
• location
• lights
