Yes. Let me clarify that a desk engineer is one who has spent his career at his desk and never really had a hobby or interest that allows him to take gear outdoors and discover how the real world affects the equipment.
Former military, tinkerers, and rednecks make great engineers. They've had experience repairing equipment that's failed in the field.
That's the key. Field experience. Any ME can and should do finite element analysis. It's just easier to trust the results and designs of those with field experience.
So your'e telling me Dr.that although I was an Incorporated Engineer with the qualification IEng MI Mech E from the Institute of Mechanical Engineers ( a body started by George Stevenson ) that because I used to get my hands dirty I was just "a mechanic " ?
No, I'm taking exception with those who seem to think that word 'engineer' has something to do with the word 'train driver', which is a pet peeve of mine. I probably should have used that instead of the word 'mechanic', sorry.
So how does this look in today's generation? I'm sure there is far less computing by hand...I come from a pre-computer generation when mechanical engineering calculations were usually done in the office on a slide rule, and physical ones by getting your hands covered with oil and filth on the shop floor.
Interesting thread. My father had a PhD in Chem E from U of Michigan, and wide experience in industry and teaching. He felt that the future of engineering schools was problematical since new grads in ChemE, and probably other engineering fields, could command high enough salaries to discourage graduate studies. He got his PhD during the Great Depression, BTW. While he was an early adopter of computers he felt that using computer simulations, rather than the traditional pilot plants in engineering schools, was ill advised. For those unfamiliar with pilot plants they are small scale, that is only 2 or 3 stories high!, installations which replicate a commercial chemical plant in reduced scale. Needless to say these are expensive facilities! In his view simulations were only as good as their data, while "hands on" experience in a pilot plant was far more valuable for translation into "real world" situations.
I remember that during his industrial work he'd be away from home for several weeks at a time supervising the final construction and startup of a plant. Hard hat and dirty hands time! The sort of thing for which the traditional curriculum had well prepared him.
And he was a good photographer!
Very interesting, I guess the math you learn in school helps you to apply it to other real life situations.Rough estimates are done by hand, say if you were in the field or at a meeting. ME's still go down to the shop floor to check on the status of critical parts assuming your company still has a machine shop.
For more detailed analysis such as, say, determining the minimum I.D. of a lens barrel so that the max OD lens doesn't get stressed (interference fit, or "crash") at coldest required temperature due to difference in thermal expansion, the mechanical engineer I work with set up an excel spreadsheet that he can enter in pertinent values to get the answer. He's done that for several common problems. That's his modern slide rule. Other guys use Matlab and write scripts. They're all based on the same math that slide rules used. I've done both for my common optical problems.
So I'd say the slide rule replacement has been Matlab and Excel. Some might use a programmable calculator but I've never seen a Mech Eng geek out that much. Measurements are done on the CAD model with inspections performed on the prototypes. Ergonomics are checked with rapid prototype models. Real fit form function done with actual prototypes (which are very close to the end product after all that modeling, unless there's Requirements Creep). Show and tells to management and customer done with the rapid prototype models and the actual prototypes: You still have to bring hardware to the table.
Is solidworks the CAD standard?

I stopped using Autocad for my small company years ago. Just way too expensive.
So I searced around for a similar cheaper or free software package which could be legally used for commercial use.
I came across Doublecad XT, now on vs 5 and find it does everything I need, it's virtually a clone of Autocad, can save and read DWG files, commands are similar to Autocad and can link directly with 3D Sketchup which is a big bonus.
I'm not on commission or have anything to do with Doublecad, but if you want to save some money and run a legal cad programme check it out.
Sewin.
DraftSight is another free CAD program. It is supposed to be very good and highly compatible with Autocad. It is distributed by Dassault Systems, the same people who supply Solidworks, but of course Solidworks itself is not free.
I've got Draftsight
People always are so confused when I tell them I am an engineering student while holding a film camera.
ProgeCAD is another good AutoCAD clone... in fact I think it does some things a bit better.
Since changing over to Linux, I haven't been able to use ProgeCAD so I am going to try Draftsight as they offer a Linux version. If it works I will forgive their spelling of draught!
EDIT: Free for Windows amd Mac, not offered for Linux, Gggrrr!!!
Does anyone know of a free AutoCAD clone for Linux?
Steve.
Very good and concise response. I might use this next time!Apologies for the late reply. I haven't had time to read many of the replies to this thread so excuse me if I repeat something somebody else has written.
As a qualified Electrical Engineer, Computer Scientist and Mathematician with 20 years of industry experience here is what I would tell them:
Engineers learn things from first principles. Analog film photography is foundational to properly understanding and conducting Digital photography. All digital systems are inherently analog in nature.
Oh, and tell them that your personal preference (which may have little to do with your technical persuasion), is simply that you prefer film.
