How to setup a tool change?

[Anonymous]

Dear all,

can someone please help me with the following questions? Therefore please see the the f3d-file in the attachement.

1. How can I mill the fine details in the logo? Obviously I have to mill the outer path with a really small router, 1mm or so. And the inner path with 3mm or so. But how can I realize the tool change while the milling process and setup this in cam?

2. How you can see the logo contains a letter "O". I can´t extrude this. Can someone give me an advice how I can fix this. The background for this issue is, I had the logo only as jpeg. Than I cutted it out from the background in photoshop and converted it in inkscape to a dxf-file. After importing to F360 the "O" has this strange setting.

Thank you very much for all your comments!

Best regards,

Sven

Hi @Anonymous,

To make a tool change in Fusion 360 CAM, you'd simply make your next operation have a different tool then the previous operation. When you export the gcode from Fusion the tool change will be automatically programmed into the gcode (although you do need to make sure your Fusion 360 tool library matches the tool library of the mill obviously). 

For your problem with the letter O, I don't know how to help, but I'd suggest making a post in the Support forum.

Best,

Ben

Yes, the resolution of your CAM question is heavily dependent on your machine and tooling. Your post processor is also critical to getting your desired result. Can you provide that information here or maybe even as a seperate post in the CAM forum?

Your bad "O" outline is a quick fix:

1. double click on the bad border (this should hightlight the whole group of splines).
2. Click "x" to turn them all into construction lines
3. Now draw a new ellipse (center point first, then major axis extent, then minor axis extent)
4. Move the point around until it matches up similar to the screen grab here:

Hi @Brady_Fulton, @ben.lorimore,

sorry for the late reply and thank you very much for your answers!

@Brady_Fulton:

As postprocessor I´m using WinPC-NC: http://cam.autodesk.com/posts/?p=winpc-nc

Your advice regarding the bad O works very well. Please let me show an another tip from Bela_Thalmann to use this app to identified where the path isn´t closed: https://apps.autodesk.com/FUSION/de/Detail/Index?id=8050506996211430178&appLang=en&os=Mac

This tool works also very good.

@ben.lorimore: The automatic tool change doesn´t work. Please see the file in the attachment. The first 2D Adaptive cleaning path is with a 3mm router, the second path is with a 1mm router. In the attachement you´ll also see the result of the whole process. Especially in the words Vintage and Mode is good to see that the small lines wasn´t milled.

Do you now what the reason for this issue can be?

Thanks a lot!

Best regards,

Sven
