Design for Manufacturing & Assembly
Design for Assembly is about optimizing the product by reducing overall cost through reducing parts, skill, tools and investment required to assemble a component or module. Design for Manufacturing is about optimizing a part by reducing overall cost through reducing materials, machines, skill, tools and investment required to produce a part.
It is a process that needs to be planned for and applied at the right milestones of a product development or continuous improvement process. Treating it like a one time event never builds the culture or knowledge to sustain it. It can be a very powerful tool in the product development process and can make the difference between profitably bringing a product to market and not allowing it to make it to market.
These attributes influence the potential for improvement and cost reduction in assemblies:
Part Count
Location & Orienting of Parts
Hardware Types and Usage
Tooling Requirements
Handling Requirements
Fastening Requirements
Mistake Proofing by Design
