Study Notes

DFMA, Design for Manufacture and Assembly, aims to make manufacturing and assembly easier and quicker without compromising on quality or functionality, leading to cost savings.
DFMA was developed in the late '70s and early '80s to optimize material costs, manufacturing processes, product complexity, and time to market.
75% to 85% of overall product costs are committed during the design stage, making early consideration of DFMA crucial for eliminating future assembly costs.
DFMA supports lean manufacturing by optimizing design early to facilitate future manufacture and assembly processes.
Benefits of DFMA include supporting concurrent engineering, simplifying product structures, reducing costs, increasing productivity, and highlighting deficiencies in product design.
Challenges in implementing DFMA include understanding interactions between product and manufacturing processes, considering associated costs of design decisions, and ensuring parallel decision-making between designers and manufacturers.
DFMA approaches can be divided into organizational and management issues (supporting multidisciplinary activities) and methods/tools considerations for successful implementation.
