I am not looking to get into a discussion about the benefits of this CAD package versus that...but I am interested to see if anyone has a PDM package that they actually like. I used PDMWorks a few years back with Solidworks and it worked pretty well. At the time, we did some exploration with...

Do yourself a favor, put reference markers around the metric units and make it VERY clear that the english units are the driving ones. I am in the process of removing the secondary tolerance block from a big bunch of drawings (inherited from a swedish company). A small slip on a decimal...

Thanks all, those are some good rec's. I downloaded the MIL handbook and I will probably order one or two of the ASM books. Miner

Perhaps a permanent rev stamp on the part itself would appease your MFG ENG. His concern is that he won't be able to tell the difference between a revA part and a rev "proto1" part. Given my drothers, I will use #'s for all pre-production (Prototype through Beta level) parts and bump to rev A...

That is awesome, I was just looking for MIL specs yesterday... Thanks!

Ryandias This is a lot of guesswork, mostly to try and figure out why someone would have an opinion about the relative strength of a GD&T callout. I am a newbie to GD&T, and I have discovered that there are about a thousand and one different ways to call anything out. Some people like...

I am looking for recommendations as to a "must have" text on Steel and Al metallurgy for product design. I have been skating by for the last few years on the basic texts that I bought in college and web resources like Matweb, but I really need an in-depth book that discusses the properties of...

What Allen4 said...but simpler Rule of Thumb... Flexural modulus applies to bending. Tensile modulus applies to stretching.

"There really isnt anyone around me that is able to follow a technical discussion at a level above generalities. When I bring up mechanics, or mathe in general I get told that all Im doing is clouding the issue. " Rule #1 - Don't use your engineering education or proof when talking to...

Has anyone had any good or bad experience using PEM's in situations where they might be exposed to shock loads after installation? I have used them in the electronics industry with no problems but I have heard rumors that they don't stand up well to impact loading. IMO, a PEM that has been...

Generally, hourly calculations don't matter as most engineers are salaried and get paid on an annual basis. Hourly calculations only come into play for you lucky buggers who get some kind of overtime compensation. I occasionally sit down and do the calculation for my work and use between 2340...

Thanks all for the good suggestions so far...please feel free to keep them coming as long as there is discussion to be had. Strangely enough, I already do a significant number of these things as part of my current job. It may be difficult to find out why someone did something in the middle of...

Leanne - That is a great quote. I think that that is something that is too often overlooked in the engineering profession. It sometimes seems like it doesn't matter what data you collect or how well you design something as long as you can create a graph of how well it will work (or think it...

I am currently contemplating a shift in responsibilities from a Sustaining/Manufacturing engineering position into a Design engineering position. I have gained a large abount of experience in the design of sheet metal, plastics, machining and some electronic assembly design, but to this point...

leanne- after reading your post again, if you were to take the texas law by the letter, it wouldn't even be leagal to use the EIT/FE designation. What do engineers (not specifically you) call themselves out there working either as an engineer intern or as industry exempt??? miner

Leanne, That is interesting...I just found on the sate of texas website a section stating: What title can I use if I'm a graduate engineer? Graduates of all public universities recognized by the American Association of Colleges and Universities have the right to disclose any college degrees...

From my State Website on licensure: "Engineer" means a person who, by reason of intensive preparation in the use of mathematics, chemistry, physics, and engineering sciences, including the principles and methods of engineering analysis and design, is qualified to perform engineering...

Leanne - What do you call yourself then? In my state, I can have "engineer" on my card as long as I don't use the almighty PE abbreviation after my name. Do you consider yourself a tech? Resident (non-licensed) doctors are still allowed to call themselves Doctor. Just no MD after...

I would say that the best way to encourage women to become engineers would be to stop setting them up for failure. I went to a fairly exclusive engineering school with about a 25% female population. I married a female engineer, have several female engineer friends and work with several...

So a PE signed off on something without having all of the data and did not do anything to make sure that he had the right data. There was a staff of PE's whose concerns were not being addressed and not one of them took the initiative to make themselves heard by the decision makers. hmmmm... So...
