1. Rhino to G-Code

I have made a script that converts lines and curves in Rhino to G-Code! Check it out here !

2. Example on how you can use the script for surfaces!

3. Hi,

Briliant !!!

Better than briliant !!!

I use Rhino from most of my CNC work, I also use it for my FARO arm.
I tried a simple setup using your script, very good. Had to add code for post, but you will be glad to know that it works.
Keep up the good work.

Max.

4. Thanks for the kind words! Nice to hear it works well!

I have begun to rewrite the script with some improvements...
Like better use of GCode for straight lines and arcs, only using interpolation for curves!
And perhaps a little better handling of joined segments! The start and endpoints of the sub segments should be used and not "overridden" by the interpolation

5. Finished X & Y on my mill conversion today. This is a gear i cut to test my mill. Ofcourse made with my script

6. This is tremendous!

7. Hello JVB,

Will be trying the script today. I have never run a script in Rhino........so where do I start? Anyone that knows how to run a script is more than welcome to speak up!

9. JVB thanks. I had found it in the book but now I have another question and it won't be in the manual.

In looking at your examples of the 3d surface above I notice you have the toolpath laid on the surface, which is understandable most of the time. However when using a ballnose cutter shouldn't the toolpath be offset from the surface depending on where the radius of the cutter is actually going to be making contact? A similar conversation came up over on the Mach forum about the use of a digitizer using a round tip for picking points.

Now my real question. If I have a surface like the one you gave as an example, and used the tool path on the surface, would parts of the surface be cut inaccurately due to the offset problem I described? Remember the toolpath as you have it is for the tip of the cutter only.

Mike

10. The problem perhaps could be solved by using the center of the cutter and not the point and then offseting the toolpath by the tool radius? I'll make a example!

11. Something like this!

12. Hi,

I am a Rhino user but I also have RhinoCAM (my CNC router isn't finished yet so I haven't loaded up the RhinoCAM or even taken a look at it yet).

Using RhinoCAM, do I still need to go through the exercise of generating g-code and asigning tool paths like you do in this thread, or is that handled in the CAM software?
