Quality Tools: Digital & Physical
Better Quality Through Design
When you think of Design for Assembly (DFA) things like parts reduction and the ability to simplify the assembly process undoubtedly come to mind. And Boothroyd Dewhurst (dfma.com), the company that is essentially synonymous with “Design for Manufacture and Assembly” has released a new version of its DFA product simplification software, DFA 10, which does focus on the reduction of parts count, on creating “single, multifunctional components with significantly improved performance-to-cost ratios,” according to the company.
What’s more, according to Dr. Geoff Boothroyd, co-founder of Boothroyd Dewhurst, “Another of the principal objectives of DFA 10 was to properly incorporate years of research carried out at University of Rhode Island on the handling and assembly of large or heavy parts—meaning those parts that could not generally be reached and manipulated by the assembly worker using one hand. This important work is now incorporated into DFA 10 in such a way that questions about part orientation and symmetry that do not affect the results have been eliminated and replaced with automatically incorporated research data.”
Which is to say that there is simplification of the approach to performing the DFA analysis work.
There is another factor in all this that shouldn’t be overlooked. While there are benefits such as reduced part count, which potentially means everything from reduced inventory to faster assembly operations, there is the likelihood that there is improved quality.
Consider: Fewer parts, means fewer possibilities for things to go wrong in assembly. Designs that are predicated on the ease of assembly means better assembly.
Which means that DFA can also result in DFQ.
