Sheet metal parts (ie. body panels) are also formed using a hydroforming process. One advantage is that tooling is reduced significantly by replacing male die with a flexible membrane backed with high pressure water. The female die cavity also holds blank. Surface finish can also be better...
Has anyone any experience in estimating final assembly variation (i.e. expected gap size & tolerance) from component part variability? I've seen programs such as "Sigmund" that estimate variabilty using solid model data & known mfg process variabilty.
My assembly is a sheet metal...
Has anyone used an add on program by VaraTech to perform assembly variation analysis on ProE assemblies?
What is a useful method for estimating final assembly build variation if individual peice part process variation is known? I'm working with sheet metal products that are hard tooled and...
Can anyone comment on useful methods to study potential assembly variation caused by piece part variation? I am interested in analyzing the design of a sheet metal sub structure comprised of 15 to 20 parts that will be welded togeather. Some parts are hard tooled, others are formed on a brake...
