Like some of you, I would like to design (or at least produce) my own cams.
For that I'm looking if there are any CAD (or CAM) models that I could download to start from.
Any info to get me going on the 3D part would be appreciated!

Sorry to have to tell you this, but you will have to design your own cams if you want any modles. I find solidworks to be the easiest software to use, but its quite expensive. I have heard that inventor is a good program by autocad, but I've never used it.
good luck and have fun.

thanks for the replies and adatesman, thanks for the model.
I'll do like you said, I'll go through the
3d design process myself. I think it's better that I know the data and physics behind it anyways.
adatesman, if you don't mind. When I get closer to the end, maybe I would like to pick your brain on some stuff and get you to validate some things before I send it over for manufacturing.

I made an excel spread sheet for the X,Y. I use this for the base and then scale it in Auto Cadd.
I’d like to see your set up on that mill Adatesman, I’ve been considering doing that myself.
Edit: I forgot I could attach it.

Is there any way to build a jig to mill a camming surface on a non-CNC mill?

If you’re doing repeats, another way to do it would be to cut one from wood, get the exact shape you want and then use a router with a flushing bit. I would rough cut it on the band saw first. Make sure you get a quality carbide bits and not one of those cheapies. I’ve met some pretty skilled machinist that can do curves on a conventional but it’s not easy.

We have two of the cnc taig mills here at school that are used for machining mini tensile and fatigue samples. (we are talking 1mm gauge length) Very nice little machines, I have done some titanium and steel on them. I only wish they would let me use them for personal projects. But then I know nothing about the modeling and g-code stuff...
