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 includes

Design for manufacturing and assembly

Design for quality

Design for cost

Design 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 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

Design Principles and Guidelines

Design for Quality

Def: Principles and procedures employed to ensure the highest possible quality is designed into product

Objectives:

Customer requirements

Robust .

Continuous improvements

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

Design for Life Cycle Product after it has been manufactured

Product delivery to product disposal
