Newbie- A pure dumplin trying to learn.

[JacquesLeDick]

Hiya Guys,

One of my first posts here.
As a belgian guitar builder/tech I'm trying to understand the world of CNC.
Most of the guitar I build are semi and hollow body's with carved tops.
Soon I'll order my first CNC machine. Gonna go for a Excitech 1312.
Ordering a machine is a piece of cake, but running it is something else...
Now I've got all my blue prints of my guitars on paper. I can get them scanned to a pdf file. But how do I start for there? Got artcam pro software.
Is there any source where I can find out more how to do this/learn CAD and CAM programs?

May the cnc force be with you,

"Is there any source where I can find out more how to do this/learn CAD and CAM programs?"

Try your local schools,
Here in USA the local two year colleges teach the subject.
It takes longer than that to get it totally.

First tell us what you currently know.
Cartesian coordinates?, plain and analytical geometry?

If this subject were easy,
everyone who could flip a burger would be doing it.

Thanks for your reply bostosh!
I'm a pen and paper man... Realizing this is not a piece of cake I'm looking for the best information I can get.
Checking schools over here in Belgium. Are there online courses you could advise?

Jacques, I don't know if art cam has changed to make it more functional for exact control of 3 dimensional parts, but I would suggest you look around at various programs designed for creating your parts then manually enter the coordinates and sections to create your surfaces. it is easier if you think in terms of building the assorted parts of your instruments, then you need draw only what you need to make the tool paths. are you planning to use a 4th axis for necks? if you are make sure your software package will handle it.

art cam will work to make inlays etc.

At the moment I'm using Rhino for mac to draw. It's going ok at the moment still a lot to lear...
I'm wondering if there is any CAM software available for mac?

For those who are interested here is a photo of a guitar I'm working on. This is hand carved, can't wait till I can draw my tops/guitars and CNC rout them... time time time...

Forgot to add a link that got me started with Rhino.

Jacques, I do not know if Madcam works for Mac or not, but it is a great cam plugin that sits right inside of Rhino. It is what I use for my guitar building...a grand total of 1 so far!

Here is a jpg showing what it can do. All done on cnc!






I had never built a guitar and with Rhino and Madcam this is what I did for my first attempt. Frets and all.

Cool stuff Mike!

Would love to get a "jump start"...
After searching the web for more info on rhino. I came across a Dutch "rhino training centre". Thinking about doing the 3 day Rhino Academy.

Would it be worth the money?

[bostosh]

I looked at that course, lot's of money, are you prepared?

Basic knowledge going into the course is required,
Geometry, drafting, etc.

Hey Bostosh,
THink I'm prepared... Now I draw my guitars with pencil on paper. Been playing around with rhino for a few weeks now. I'll call them tomorrow to discuss a few things.

[bostosh]

Draw the guitar plan view profile, then overlay graph paper and create a table of the intersect points from a common origin, then key in the points and spline through them. (Rough idea of doing cad.) or draw,scan in, load picture as background on cad system digitize on screen, spline it, or draw, scan with tablet digitizer, or just let someone else do this for you.

So many ways to get the same results.
