My company started having a lot of problems with one our primary casting suppliers. It turns out that there have been some significant changes and this company will no longer be an option in the future.
The company supplies sand castings ranging between 50 and about 800 pounds. It isn't my job...
Has anyone used a good web meeting software? I just had a web meeting and it was horrible. I used Microsoft Live Meeting. It was not good but OK when I was showing the powerpoint, but when I was showing models it was awful. Kept locking up the refresh was bad. Any suggestions?
Is there a more technical way of saying that a bolt is backing out?
I am writing a service bulletin and want to let the customer know that a bolt tends to back out over time.
I have a large assembly with 2 different versions. I have all the components shown in the generic and two instances. I would like to simplify my family table by grouping. Group 1 is shown in instance 1 and group 2 is shown in instance 2.
I can add components to the family table, but when I...
I have two rollers in Hertzian contact. One roller is driving the other. I put a coating on one roller and want to determine how much it helps. I have the ability to determine the RPM & torque of both rollers.
This seems like a simple enough case that it could be tested with some ASTM code, but...
You can see the attached poorly drawn sketch, but I am looking for something kind of like a shoulder bolt but the shoulder part is a lot bigger than the bolt part. (Something in the neighborhood of a 1" shoulder to a 0.25" threaded)
This is not going to see any load it is a target for a prox...
Has anyone used DMLS for production parts? I think I may have found an ideal application for this technology.
We do a lot of hydraulic manifolds, so they are low load (about 5000 PSI MAX) and have a complicated geometry. It would also change the way the manifolds are designed. It would make...
Does anyone know where mapkeys are stored in Pro/E?
I launch Pro/E from Pro/Intralink off our network. We have a standard config file that loads so we all have the same set up. I wrote some mapkeys and they worked fine until I closed Pro/E. When I wrote the keys I saved my config file on my C...
My current company will pay for me to get my masters degree, but it can't interfere with my work.
I am in Houston, so that leaves me with night classes at U of Houston or Rice
or
Something on line.
I want to get a Masters in Mechanical Engineering, probably in Mechanics or Machine Design. I...
I really like the old engineering drawings done by hand. I would guess that there are very few practicing engineers that could produce one anymore. It is a shame that it is a dead (or dying) art.
Has anyone come across any websites or other resources that have interesting old engineering drawings?
Is there such a thing as a laser screen? I am thinking of having a series of horizontal lasers so that when objects pass through the screen I can tell which lasers were tripped and when they were tripped. I could use that information to build a profile of the object that broke the screen. It...
Does anyone have a good reference (on-line or in print) for Steel (other metals would also be too good, but I am looking specifically for steel) I have a BS in Mechanical Engineering so I know a the theoretical fundamentals (Modulus of Elasticity, basic chemical composition and structure...
Has anyone used the Adobe 3D PDF.
Does anyone have any thoughts on the security of the data?
If I send a native SolidWorks file to a customer they can do anything they want with it. If I send a STEP or IGES they could still go behind my back and get tools made from the files and send it to...
I have been using wildfire since 2005 when I started my first job. I have recently taken a new job at a different company but still using wildfire.
When I am creating a drawing it is very, very, very difficult to grab and drag a dimension for better placement. I have the same issue with BOM...
The company I work for does not currently have a 'design best practices' or 'lessons learned' list or document.
We have a product that we have designed and built and are selling. It’s for the most part a good product but it does have some issues. I did not design the first product but I am...
I have a pin in bending with a transverse hole. Getting the stress concentration factor is pretty straight forward.
However the transverse hole is on a section of the pin that is fully supported (360 degrees) with a bushing. My gut feeling is that the bushing is going to 'cancel out' or...
