Product Related Data Goes Digital

• Unit 1

3
Digital vs. Paper-Based Data

• People are getting more connected
• Through Internet or local area networks
• Digital data instead of paper-based data

4
Product Related Data

• Initial brainstorming ideation phase
• Artistic design sketches
• Blueprints
• Assembly drawings
• Manufacturing plans
• Assembly manuals
• Service and maintenance documents
• Cost estimations

5
Blueprints

• Type of
• paper-based reproduction usually
• of a technical drawing
• documenting
• an architecture or
• an engineering design
• The term "blueprint"
• the visual aspects of prints
• contact printing process of cyanotype

6
Computer-Aided Design Drawings

• More recently, designs created using
  Computer-Aided Design techniques may be
  transferred as a
• digital file directly to
• computer printer
• plotter
• In some applications paper is avoided
• work and analysis is done
• directly from digital displays

Digital Product Related Data

• Part and Assembly Modeling
• Surface Creation Editing Tools
• 2D/3D Drafting Detailing
• Photo-realistic Rendering (Materials,
  Environment)
• Display and Visualization
• Camera-based Animation
• Import/Export
• Object and Group Properties
• Material
• Center of Gravity
• Volume
• Weight
• Density
• Moments of Inertia

8
Cost vs. the Whole Product Lifecycle

• It is not just the COST that matters
• Changes in the whole product lifecycle
• should be considered
• not just the adjustments related to
• savings
• increasing productivity
• cut of the production expenses

Implementing Changes

• Product structure can be complex
• Hard to implement changes which
• affect production
• need lot of time
• recourses
• finances

10
Product Changes Constantly

• Designing a product
• for manufacturability assembly
• involves collaboration among various engineers
• needs to be documented

11
Sharing the Data

• Information needs to be accurate
• Faster than it was before digital era
