ENGINEERING
 The ‘WALL’ between
manufacturing and design
engineering
 Only when the design
engineering department
completes its work, then only
the process planning begins
Manufacturing department
includes early stages of design
It includes
 Design for manufacturing
and assembly
 Design for quality
 Design for cost
 Design for life cycle

4. Why Concurrent Engineering?
• Pace of market change has increased
• Companies must keep pace with changing markets
• Decisions made sooner rather than later
• Reduces/eliminates repetition of tasks
• Reduces waste and reworking of design
• Product quicker to market
• Maximises company profit
• Company operates more efficiently

5. Design for manufacturing and
assembly
 70% of life cycle cost of the product is determined by
basic decisions made during product design
-Material for each part
-Part geometry
-Tolerances
-surface finish
-Assembly methods to be used
 Organizational Changes in DFM/A
 Design Principles and Guidelines

6. Design for Quality
 Def: Principles and procedures employed to ensure the
highest possible quality is designed into product
 Objectives:
 Customer requirements
 Robust .
 Continuous improvements

7. Design for Product Cost
 Major factor for commercial success
 DFC refers to the efforts of the company to specifically
identify how design decisions effect product cost and
develop ways to reduce cost through design.
 Costs of inspection
 Purchasing
 Distribution
 Inventory control
 Overhead

8. Design for Life Cycle
 Product after it has been manufactured
 Product delivery to product disposal
 Instability
 Reliability
 Install ability
 Reliability
 Maintainability
 Serviceability
 upgradability
