Mastering efficiency through design for manufacturing and assembly
DFMA is simply a common-sense engineering way of making sure that there are components, not just systems, in place to ensure new products are both functional and cost-effective to build. If such principles are applied early in the design phase, intervention and speed-up of production and the design bearings with quicker and easier assembly, and better quality. Design for manufacturing is about how to make each part as simple and low-cost to make, all the way down to what material you choose, tolerances, tooling, and processes. Design for assembly is not so much about those parts as it is about how those parts come together in a way that uses the fewest possible number of things to assemble, permits manual handling, and can sidestep as many fasteners or adjustments as practicable. In order to facilitate the method of manufacture and assembly as described, there are several critical DFMA liberties: (a) the base members 52c need not be precise; (b) The inner cavity may be either free...
