I work as a cnc machinist and drawing 3d objects is half the battle, putting toolpaths to complex shapes and making the part is hardest.

Ink have you ever looked into 3d printers for your solid models?  Could take your models and make them real.

I use Mastercam for all my parts and its pretty easy to make 3d stuff you just take 2d lines and revolve/extrude chains into solids.

I am not downplaying how hard it is to create exactly what you want sometimes lol...it's like hey I want to trim this circle down what are all these error messages!


They also have direct metal sintering now that creates solids layer by layer out of metal...crazy expensive but would be cool to see a metal dinosaur lol

[VonMessa]

Haven't touched on 3d yet. Mostly weve been drawing different brackets but we did this to learn how to use polyline edit (PEDIT) and the hatch command. Easy enough and kinda fun but im not smart enough to draw without plans or at least the peice in question and a measuring device of some sort.

Also, there is as much art as there is science in drawing/designing/fabricating a part or assembly.  Engineers are as much artists as a sculptor or painter, their "art" is just more quantifiable since all the pieces must fit together.

The most gratifying part is when an idea...





becomes reality

You do that on your Smithy?


I'll have to post some of my brain buster parts lol

When you get into 5 axis work you have to start thinking outside the box.

Yup.  Made from an axle of some sort that I got from the scrap yard. 

I've had experience with the 5-axis machines before.  I served a tool/die apprenticeship and worked in a mold shop for years before my current job and I've used MasterCam, SolidWorks, and ProE before.  It does take some out of the ordinary though process sometimes.

Amazing machines.  If I had the coin, I would have bought one.

I have seen them, pretty crazy stuff, but awesome, and way to expensive for my blood.

Most engineers today are far lacking in the skill to be an engineer. Lots of schools spewing them out left and right. Back in the day folks worked in the shop then decided to go into engineering.

[Seanaldinho]

Do not sell yourself short.  It is not as easy as you think.  I know a lot of people that just cannot wrap their head around a 3rd angle projection drawing.

As for being smart enough to draw a part?  Needing dimensions to correctly draw a part does not make one stupid.  

I dont have a problem with working in 3D but we just havent advanced that far in class. We have done 3 views to make a 3d object 2 dimensional though.

I dont think im stupid Im in the top 10 of my class (about 500 kids in my class), Im just more mechanical over designer like. I cant take something and draw it up in my head I have to see and do to understand.

Also if someone tells me to make something then I have trouble unless they give me either a drawing or show me how they want it. Im not good at piecing things together in my head. I guess its the photographic memory.

[Belial]

Some parts I have saved on my computer I didn't have any of Mastercam at home but could get some off my work computer.
It's my dad, myself, and 1 employee in our shop...I am the only one running the CNC stuff, but my dad does the quotes and Russ welds and does a bit of everything lol.



Made 200 of these theres some pretty cool mill/lathe work to them if I had a closer pic.



Made 30 of these from Brass castings .



A 3d model of the part before I put toolpaths too it.

[Belial]

200 of these as well they are about a 45 min part each boy was I glad to finish them, they have milling, tapping, ID chamfer all kinds of fun stuff goin on lol



Haas ST 30 with live tooling, boring threading tapping all done without loosening the chuck.  I mirrored the part to save material when parted in half.



Grinder shaft for Merck Pharmaceuticals cut with waterjet/lathe/and mill.



The whole grinder layout, I don't have a pic of the whole completed assembly but the thing cost about as much as a vette when done lol.

^^^^^ This.


EDIT: The young engineers coming up these days rely far too heavily on AutoCAD, Solidworks, etc.


I actually saw a design that involved us installing a roller into a moving fixture. AutoCAD didn't give the red line, so the engineer said, "It will fit fine."


My response was, "Yup it'll fit fine, but once the assembly is welded into place you'll NEVER get that roller out for replacement."


He went back to the computer. (Not "drawing board".)

That's the beauty of designing and fabbing under 1 roof lol

Oh man I hear ya.

We start with raw material and build some rather large (multi-million dollar) systems.

The problem is that we have engineers growing out of the freaking woodwork and they all want to re-design the wheel. I'm talking about young guys and girls that will try to design some overly complicated, world beating assemblies yet they couldn't change a flat tire. It doesn't help matters that we've been in the prototype stage for 75% of our products in the last year.

Makes for a rough day when I spend more time wielding a grinder and red-lining prints as opposed to turning a wrench. In fact, as I type this, I'm sitting in my hydraulic fluid stained work shirt with metal shavings firmly embedded in my hands.

Darned kids.

looking through some photos of my tat shop I found these...the only pic I have of some portrait paintings I did, photo was takin in 2010 this is 7 years after I started painting regularly,....that's my son Khanan posing

would you believe Bob Ross lived in my neighborhood?
