Why improve with DFA, why not line balancing Authentic Dede Westbrook Jersey , 5S or other lean engineering actions? If a merchandise contains 1 ton of steel which requires 10 processes and that takes 5 hrs, thin manufacturing may only reduce the 5 Hrs slightly. A project change could reduce the amount of steel, the number of processes and the lead time. In terms of improving merchandise cost, quality and lead time Authentic Cam Robinson Jersey , the gains are highest with Design For Assembly (DFA).

DFM approaches started to be used in the 60s. In the 70s, analytical evaluation tools started to get developed such as the Assembly Evaluation Method (AEM) developed at Hitachi and the Design for Assembly (DFA) Method developed by Geoff Boothroyd. Further advancements and variations of these methods happened during the 80s and 90s.

An important point to bear in mind with these tools is that they are evaluation tools 鈥?to evaluate a design you first must create a design. Granted, through continued use of these tools, the user will most likely learn what works and doesn鈥檛 work and feed that into their initial design. A competent DFM designer however will have an understanding of the principles that under pin these tools and apply that knowledge in their initial designs. The ultimate goal in Design For Assembly (DFA) within a lean organization should be to design it right first time. After all it is Design For Assembly (DFA) Authentic Telvin Smith Jersey , not Re-Design For Assembly

An example of a Design For Assembly (DFA) principle is to design for vertical assembly where parts are assembled in a straight down motion. This means gravity can be taken advantage of to provide positive location rather than a fixture. This also future proofs the design for a move from manual to robotic assembly.

Another example is zero drawings design where the assembly of a merchandise is instinctive and mistake proof without the need for manufacture drawings. This could be with assembly features like multi-sized tabs, used to create parts that will only fit in the correct location. An everyday example of this is if you have ever changed a flat wheel on your car. You may have noticed that the holes on the wheels are quite a bit larger than the wheel studs, this allow the wheel to be easily located on the
