This is a tolerance analysis tool that helps designing mechanical assemblies that must work together.
This is a tolerance analysis tool based on Microsoft’s spreadsheets, Excel. This can help analyze if parts in an assembly will work together well. This particular version helps do a non-linear analysis to take into account higher order tolerance mismatch effects. Each part in an assembly is built to specified dimensions. But, that alone does not ensure an assembly will fit together and work well. Tolerances in the dimensions stacking up the wrong way can cause problems easily. A design engineer must perform a tolerance analysis when developing a product to ensure his design would still work under all the design conditions and meets design cost budget. Tools like this helps a lot as typically tolerance analysis is not carried out thoroughly, being a tedious manual process otherwise. This is particularly so when you have more than one stack-up. Most real life assemblies will have multiple configurations.
Some of the useful features include up to 200 tolerance stack ups with associative dimension management. The tool can produce worst case, RSS, and modified RSS results with linear and non-linear stack-ups. Graphical output is made available for stack up results. You are able to add an image of the assembly stack up. An automatically generated summary of all the stack ups in the analysis is made available. A “times used” alert feature that warns you about same dimension being used in more than one place. Being based on Excel that everyone is familiar with, you can get to start using the tool right away. The interface is straightforward. This is a very good tool and is a good candidate for trial, if you work with these kinds of problems.
