/diy/ - Do It Yourself

You will need to open the drawing in Bobcad or mastercam and pick you machine, set the tools material and toolpaths produce the code (generates automatically) save this on a USB or 3.5 HDD (typical) load the program to the CNC and do a Dry Run. If you do not know how to machine then you need to find someone that can!

Are you sure the trucks are made of aluminum? Because I doubt they are. Also, good luck not crashing the CNC, because it sounds like you have no idea about CNC machining.

I know for a fact that they are made from aluminum and I also have no idea how to operate the machine yet. I am taking a course in 2 weeks though.

sounds dangerous bro

>How would I input the CAD drawing into the machine?

Thats multi-axis G-code.

Smartcam and the like (there are others) post process 3d data into G-code that the CNC can actually use.

Like this: 3D model (iges, step, a dozen other formats)---> CAM software (smartcam, etc)---> G code for cnc usage.

CAD/CAM is an entire education unto itself tho, and to say you want to make custom trucks is kinda putting the cart before the horse.

What OP should consider is a way to modify what you can buy (Aeras) to make them more "downhill-able". You don't typically scratch build a car simply cause you want one, right?

>where do I buy raw aluminum (good quality)?

Alumnium bar stock distributors - Google ffs, They'll want minimum orders or prepare to be raped.

>(Aera trucks if anyones interested)
Probably not

Oh and most of the trucks I've looked at seem to be forged aluminum. Which makes them much stronger than drawn barstock

At least for fatigue strength & bending

are you sure your geometry is gonna work at high speed?

>>356382
sigh, magical CNC will not build you a truck. it's not one part, it's many, and of different materials that all work together.

"CNC" doesnt mean you do not have to design, or know materials. it just moves the leverson the cutting machines for you, more or less. "CNC" doesn't "know" anything.

>>356382
If you need to ask ANY of that, then you do not have anywhere near the ability to do this yourself. This is not a drag and drop operation. Considering it's a CAD file to begin with you would need to do plenty of modifying to the drawing just to be able to toolpath it.

Full time CNC programmer, and former CNC machinist here.

I appreciate your ambition, and wish you the best of luck with it, but it sounds like you have an overly simplistic idea of how CNC machining actually works. There are many considerations, it's not just a matter of tossing a hunk of aluminium into the machine, loading a cad model and then hitting cycle start. Several questions have to be answered.

What type of CNC machine do you have? Mill, Lathe, Millturn? How many axes? What kind of material are you going to use, (bar stock, billet, etc). How many setups are required machine the part? How are you going to securely hold and locate the part during machining? What kind of cutters do you have at your disposal, and will they suit your dimensional requirements? Are you planning on making just a couple of these or will it be a mass production item? Is cycle time a concern?

Running a cam system isn't as straight forward as some people think, it is definitely not an automatic, model in --> toolpath out, process. Sometimes seemingly simple parts can throw you a curveball and pose unexpected challenges.

As anon said, you may find it easier and cheaper to modify some existing trucks to suit your needs. If you do plan on starting from scratch, that's cool, keep us posted on your progress.

Good Luck
