Feedburner Funkiness

By Kate

Hi everyone,

Many apologies if you’re an email subscriber and received the post from September 7 this morning. We’ve encountered some Feedburner funkiness and have resynched, repinged, etc. etc., so all should be in order now.

The post you were supposed to receive is by Michael Moser and entitled Mind the Gap.

Enjoy!

Mind the Gap

By Michael

Whereas virtual designs are 100% perfect – as designed, with perfect circles, perfect corners and razor-sharp edges – the real world is not.

Any manufactured part which is assembled from pieces and which consists of various materials, comes under the influence of Mr. Thermodynamics and his physical gang members Mr. Temperature and Ms. Pressure. With all those parameters and forces applied during the fabrication process the resulting product is at best close, but never fully identical with the originally designed dimensions.

Important to note: with every percentage we want to minimize these dimensional deviations, represented by gaps and misalignment in assemblies, we increase manufacturing cost due to additional investment in equipment, better materials or just more effort to optimize the machinery.

Depending on the product this will be necessary and justified: if we manufacture a submarine boat we need to take care to have the outer skin absolutely water-tight under all operating conditions and with a safety margin. Here very little deviation is allowed in order to not jeopardize security. No compromises. Building a submarine or alike is complex and expensive.

For less demanding situations the control of dimensions is less critical.

A bicycle for instance needs to meet a set of functional specifications, i.e. it needs to be durable and parts should move without friction. However the physical constraints on the product in operation are less severe than in the submarine case, which means that certain dimensional deviations of assembled parts can be accepted. This results in manufacturing process which is less demanding.

Another view is on aesthetics: we want a car to look good in every aspect. The gap between the hood and the chassis for example needs to be straight, close (but not too close) and overall needs to suite the expert’s eye. Intuitive buying decisions may depend on this feature. I am not joking. So this is important too!

I guess I sufficiently hit on this point: when we manufacture a virtual model we have to expect dimensional deviations. We therefore need to understand, control and design for those deviations – preferentially before it is found out from the first product which comes off the assembly line.

This was the introduction to present the domain of competence of DCS Inc. or Dimensional Control Systems Inc., a 125+ employees company headquartered in Troy, Michigan USA, with local representations worldwide. DCS is also a Gold software partner of Dassault Systèmes and they have captured their knowhow of dimensional engineering and process capabilities into a suite of tolerance analysis software applications (3DCS CAA V5 Based) which helps designers and engineers to anticipate real life conditions put on ideal designs. Good news is: 3DCS software is fully integrated in the DS 3D PLM solution and respectively the brands CATIA, DELMIA, ENOVIA and SIMULIA.

What DCS does is clearly heavy duty engineering simulation with a lot of differential equations involved. Don’t try this alone at home. If you are a manufacturer who needs to control dimensional tolerances as a function of production cost, a good advice is to let DCS assist you.

One prominent project where DCS is already part of the competence team is ITER, the nuclear fusion reactor to be built in Cadarache in the South of France. ITER is a highly challenging endeavor with a long list of technical unknowns. With the objective to master fusion technology as an unlimited source of energy for man. DCS’ job is to watch over the design of the reactor vessel built to sustain the physics involved, boost the understanding of dimension tolerancing and gain a certain level of trust for predicting results. (For more general information about ITER, and some 3D virtual fly throughs, go here.)

Ladies and gentlemen, mind the gap.

To get in touch with DCS, find their information file here or directly on the PLM MarketPlace where 3DCS products are referenced. John Sienskowski is your contact to call for help.

Soon more from the beautiful world of applied engineering.

Best,
Michael

The 3DVIA Mobile App is Finally Here!

By Cliff

I am an iPhone App junkie!

I play iPhone Apps whenever and wherever I can. My wife has actually said to me, “Put down the iPhone Cliff, and talk to me”. I tried suggesting that I just text her instead. She didn’t think that was funny.

I know there are plenty of iPhone junkies out there like me, downloading every FREE game, puzzle or gadget you can. And if you like the app, you purchase the full version. However, I must admit, that most apps I have paid $.99 or $1.99 for, I quit playing after 2 weeks, maybe a month. The one I am still enjoying is the 3DVIA Mobile App (I was on the BETA team for the last couple of months). I’m sure you are thinking that I am supposed to say that, but it really is true.

The reason I enjoy the app, is not that I can view all of my models, or the thousands of 3DVIA.com public models on my iPhone…It’s the collage feature, which is built into the App. This is fun!

The Collage function allows you to take a photo with your iPhone, then download any 3D model from 3DVIA.com, and add it into the picture, in true perspective. How cool is that!?! You can add 3D models of people into a picture of real people, you can add 3D models of furniture into rooms, you can add cars into your driveway. All this in the palm of you hand, wherever you are. The possibilities are endless, but I did create a video of some great uses for the app here on 3DVIA.tv.

All the details on the new 3DVIA Mobile App, including where to download are all on the 3DVIA Mobile page:  www.3dvia.com/mobile.

In fact, 3DVIA is opening a contest asking you to create any image with our favorite dinosaur Tex Rex, with the chance to win an Amazon Kindle™. All the details on the contest are found here.

Oh, and I must tell you the App is FREE now, so download it today, as the App will list for $1.99 soon.

Also, I need to say a special thanks to Gérald Guyomard, and his team for development of the 3DVIA Mobile App – Excellent Work! You not only gave me my favorite App, but also allowed me to play my iPhone at work – Sweet!
