Background of the DFMA tool
Design for Manufacture and Assembly
(DFMA) is the process of proactively designing products to optimise all
the manufacturing functions and assure the best product performance.
Parts are designed for ease of fabrication and commonality with other
designs. DFMA encourages standardisation of parts, maximum use of
purchased parts, modular design, and standard design features. Designers
will save time and costs by not having to “re-invent the wheel”. This
tool is sometimes known as Design For Manufacture (DFM) and Design For
Assembly (DFA).
The DFMA tool
The design stage is very important in product design. Most of the
product lifecycle costs are committed at design stage. The product
design is not just based on good design but it should be possible to
produce by manufacturing as well. There’s no point having a good design
if it is difficult, impossible or costly to produce.
The
manufacturing of a part or a product must be considered as being part of
the design of the part or product. It is not a separate entity that
someone else deals with after the part or product has been designed. The
DFMA tool is a structured process that encourages the design engineers
to very seriously consider how their design will be manufactured. The
DFMA process steps are:
- The cost of re-work
- Manufacturing problems both current and past
- Number of parts
- Modular designs
- Standard components
- Ease of manufacturing
- Manufacturing capabilities
- Mistake proofing (poka-yoke)
- Parts orientation and handling
- Automated production
- Fasteners
- Flexible parts and interconnections
- Assembly direction
- Adjustments and settings
- Design tolerances
The DFMA training course
The DFMA tool can be used where any parts or products are being
developed and is used extensively in the Automotive environment.
Essentially the DFMA process should be applied in the development of any
products where, efficient and effective manufacture and assembly is
important. This could be in new product concepts or if the market is
very competitive and a product advantage is needed.
This one day on-site
DFMA training course
starts with an overview of the DFMA tool and the DFMA process.The
intent of this and all our training courses is not to tell or show the
trainees what to do but to impart the capability to perform the required
tasks. There is no limit to the number of trainees but we strongly
recommend no more than 5 individuals attend per course. We find that if
there are any more than this the training becomes ineffective and
wasteful.
This course is targeted at the product design engineers, the
manufacturing engineers and the programme managers delivering new
products. This training course is given in English. All our courses are
designed to be informal and are based around a series of discussions and
practical exercises. A DFMA excel template is provided.
