Overview of Product Design and Production Engineering

1
Overview of Product Design and Production
Engineering
2

• Considerations
• product design - critical design steps
• software for drawing, analysis, modeling,
  simulations, testing and design
• Concurrent engineering
• design for quality

3

• Product Design
• need for automating design process in CIM
• generates the initial product data and drawings
• Functional automation - islands of design
  automation
• potentially productive but has negative
  enterprise related effects
• Single Enterprise database with a single image of
  all product information - ENTERPRISE DATA
  INTEGRATION
• Communications-
• LAN - supports inter-departmental design
  activities
• WAN - will link enterprises and their
  contractors/suppliers

4

• Organization Model
• Recall section 2-3
• Design team -
• product design
• analysis
• materials selection
• documentation (both design and production)
• Production engineering
• production standards(labor, process, quality)
• Integrated Product and Production design

5

• Design Process
• Form, Fit and Function
• Form - desired shape, style and character
• Fit - relates more to market functions
• Function - performance, reliability,
  maintanability
• Conceptualization
• Typical - similar to previous designs -
  repetitive design
• Atypical - product need that is totally new -
  concept approach
• (Discuss some examples)

6

• Synthesis
• material specification
• initial additions of geometric features to the
  conceptualized design
• dimensional details
• DFA and DFM (DFMA)
• Analysis
• analytical techniques such as Mass property
  analysis or Finite element methos

7

• Evaluation
• checks design against all requirements, form,
  fit, dimensions, etc
• match manufacturing and assembly requirements
• Rapid prototyping
• Documentation
• detailed drawings and assembly drawings
• details of materials and parts
• BOM
• Product electronic data files

8

• Concurrent Engineering
• design and production design considered together
• Read through section 3-4, and 3-5
