Description of the training

“Using Excel for tolerance analysis comes down to asking mechanical designers and engineers to be mathematicians.”
Pierre Lafortune
Enventive Application Engineer

When tolerancing, the ultimate goal is to ensure that each stackup remains within the functional limits defined in the FMEA. Tolerance analysis is never perfect, and mainly depends on three variables:

– The tolerance calculation method; for example, Worst Case, RSS, or Monte Carlo.

– The chain of dimensions, and our ability to properly list and calculate them.

– The hypothesis-defining parameters we neglect, either due to irrelevance or difficulty to predict; for example, thermal expansion, variational kinematics, or multiple floating holes.

GD&T trainings are key for a good understanding of tolerance analysis principles and tolerance calculation methods. The basics can be communicated using an Excel spreadsheet, but when it comes to geometric product specification (GPS) conveyed in the ISO or ASME standards, it’s obvious that Excel calculations become exponentially complex.

But can we really expect to avoid geometric analysis when standards and customers require proper GD&T tolerancing on all of their 2D drawings or 3D CAD annotations?

Engineering teams know that Excel is only good for low-severity, simple 1D stack analysis. Beyond that, neglecting geometric tolerances becomes an increasing waste of money and probable risk of:

– Wasting time doing stack analysis to tick boxes in a product development process

– Making empirical iterations of additional prototypes

– Causing scraps and engineering changes in manufacturing

– Experiencing major recalls

Honestly, there is no single tolerance analysis software on the market today that solves every need. There are major differences between 1D, 2D and 3D tolerance analysis software. At Enventive, we understand that different needs require different solutions, and that’s why we’ve expanded on our product offerings to provide you with the best solution for your specific mechanical design challenges.

Enventive’s unique mathematical solver powers all three of our software solutions: Enventive Concept, Enventive 360 and Enventive 3D&T. With these three solutions, we support your tolerancing needs with 1D stackup analysis, 2D variation analysis, 3D tolerancing, and enterprise tolerance management. You can also see by yourself how our solutions compare.

We’re always here to help. Feel free to contact us to let us know what your applications and goals are, and we’ll help steer you in the right direction to solve your tolerance analysis needs most effectively.

With Excel tolerance stackup analysis, you are often limited to 1D stacks, and many parameters are neglected. Some industries don’t require calculating the impact of GD&T on drawings that rely on general tolerances. In such cases, Excel stack analysis may be sufficient to fulfill FMEA requirements.

The standard process consists of using Creo, CATIA, Siemens, Solidworks or Inventor CAD software for modeling and editions of 2D drawings or making 3D annotations directly on the model. Most often at the end of the design, Excel is used for tolerance stack-ups.

Considered by some as CAE software, Enventive Concept can work within this standard process with greater flexibility. Keeping the same CAD-Excel process, you can import your CAD model into Enventive Concept for variational analysis. You will be able to optimize all the dimensional and geometrical tolerances, plus your choice for datums. Smart tolerancing leads to reducing the number of stackup contributors. Fewer contributors results in less need for control in manufacturing, and thus significantly lower overall product costs.

No. The great thing about Enventive Concept is that designers and product engineers use Enventive Concept with a high level of confidence after just a single training. Users create exhaustive variation analyses that accurately reflect their design’s reality and the limits of their assumptions.

Our customers tell us that Enventive Concept is far easier to use than competing software tools. Check out these Case Studies, or book a free demo to see how Enventive Concept Concept actually works.

Yes. Because of its unique solver, Enventive Concept falls into the category of CAE software. Its functional modeling approach combined with its predictive capabilities makes Enventive Concept the only Variation Analysis Driven Design software of the Simulation Driven Design solutions promoted by Altair and other CAx key players.
