CETOL software

CETOL software

CETOL software

(OP)
Has anyone use it very well? You can easily get bad results, is heavily dependant on the constraints... So Please recommend a good training center/mentoring and more affordable than sigmetrix? it can do worst case and statistical tolerancing, in the latter it calculates the sensitivities of each dimension instead of a monte carlo simulation. They tout it as a better approach

thanks

RE: CETOL software

From my experience with their competitor, VSA, I'd say that experience and hands-on practice are going to be the best training. These tools are more like FEA, where the user needs to understand the underlying methods and is capable of doing the task without the software, just more slowly. After that, it's just working with the program until some level of speed is reached.

I have mixed feelings about the Monte Carlo complaints. While the purely algebraic method offers some assurance, the real product will be produced in a real factory and will be more in line with the Monte Carlo method. In addition, at least under the VSA system, the Monte Carlo approach was extendible to external software, allowing analysis of non-geometric effects.

For me, the largest problem is that to make it worthwhile actual factory production capability needs to be known. It doesn't matter so much what tolerances are allowed for on drawings as what variations will be produced.

RE: CETOL software

I doubt you will find anyone besides Sigmetrix to do training due to the limit usage and specialization of the software.
Like 3DDave said, practice and hands-on are the best tools for becoming an expert in the use of CeTol and VSA.
