Introducing CAE Into Your CAD/CAM Workflow: Getting Onboard
January 25th, 2012 by Jeff Rowe
By now you’ve almost certainly got MCAD and CAM tools as a vital component of your business. With them you’ve hopefully seen how they have positively impacted the way you work, as well as the way you interact with your customers and vendors. Looking for a way to further increase your productivity, while continuing to optimize your processes?
If you haven’t already, it’s time you considered integrating tools into your workflow for simulation and analysis of virtually any aspect of the product development lifecycle. Although known in some circles as computer-aided engineering (CAE) tools, that acronym has largely been replaced by simulation and analysis, although they all mean roughly the same thing.
It wasn’t all that long ago that CAE was relegated to the latter stages of the design and manufacturing (product development) process — too many times as an afterthought. This is changing, though, on two fronts. First, realizing the potential payback in terms of reduced production time and getting it right the first time, many design and manufacturing organizations have moved CAE tools further forward in the development process. Some are even using them in the earliest stages of design, the conceptual phase. Second, software vendors are getting better at integrating CAE with their CAD and CAM tools.
A major roadblock to CAE’s wider acceptance has been the perception that only high-priced analysis specialists (math PhDs?) could understand and work with CAE tools. While specialists are required for some of the high-end tools for performing complex analyses, there are many CAE tools now on the market that require just some basic training and practice to become proficient in a relatively time.
Admittedly, all CAE tools require a technical mindset, but you don’t necessarily have to have a doctorate in math anymore to run many types of analysis and simulation. It really just requires familiarity with the interface of a CAE tool for creating and loading digital models, and then reviewing and interpreting the results. A really nice thing is that many CAE tools now work from within the familiar UI of your CAD or CAM tool. Finally, computer prices that continue to drop have helped popularize CAE tools, because some of them require a lot computing horsepower when working with large assemblies or very precise engineering constraints.
If this all sounds easy, it is to a point, but there are some caveats. That’s what we’ll discuss next time, as well as the most commonly used CAE tool — FEA.
