CONCURRENT 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 includesDesign for
manufacturing and assembly
Design for qualityDesign for costDesign for life cycle
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
Design for manufacturing and assembly70% 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 usedOrganizational Changes in DFM/ADesign Principles and Guidelines
Design for Quality
Def: Principles and procedures employed to ensure the highest possible quality is designed into product
Objectives:Customer requirementsRobust . Continuous improvements
Design for Product Cost
Major factor for commercial successDFC refers to the efforts of the company to
specifically identify how design decisions effect product cost and develop ways to reduce cost through design.
