In a previous submission, ideas were offered how to measure complexity in CNC parts. Sheet metal parts can also be complex and need a ranking system early on in the design cycle. Since both CNC and sheet metal have a surface element count, The same complexity approach can be used. The simplest part is a bent angle -This is the standard of simple and has x surfaces Your complexity value is total number of surfaces of complex part divided by surfaces in a bent angle. Other value to consider - holes, notches, slots, emboss and indentations etc. should they be 1, 2 or 3? My suggestion is get with top sheet metal customers and test various values, ratios, operations and criteria to determine a worthy system. The benefit is ranking part designs and discovering too complex unworkable designs early before committing to building, prototyping and other manufacturing operations.
