Toolpath strategy

Hi everybody,

.https://www.cnczone.com/forums/attac...d=452224&stc=1https://www.cnczone.com/forums/attac...d=452222&stc=1
I'm triying to machine a complex shapes, for a wallpanel drawn with rhino-grasshopper
I want to machine the closed triangle and keeping straight corner inside... I dont know which strategy i need to use in alphacam.
I want machine with VBIT 90°, but i can't machine with this tool and advanced 5 axis strategy. I try machining along polyline, whith corner inside as curve to follow (in black on the picture), it works but i can't give angle to my tool to machine the dependant face at the same time.

Thanks in advance.

Julien.

Julien, hello!
Where is the picture or project?

Hello 31010, can't you see any picture on my post?? There is two...
Anyway i have add files as attachment, 2 pictures and zipped alphacam file.


Thanks.

Take a 120 degree cutter. And do 3d engraving

Hi, thanks man !!!

Can you send me the .ard file please?? But i'm triying to machine with a 90 degree cutter, i do not have a 120 @ my school... Any idea to give the tool the right angle ?

All the best

Julien.

I have attached the file in a previous post.
Do you have a 5-axis machine?
What is the diameter of your cutter?

Oh sorry, i haven't seen attached file... But i can't open "incorrect file version" i'm on 2020 version

Yes i have a 5 axis CNC (centateq homag) et my post-processor can manage 5 axis toolpath...

Thanks.

See the bottom link in the previous post.

yes it looks perfect, is the piece machined with 90 cutter??

Yes, a 90 degree cutter. But this is an equilateral triangle. And the angle of inclination of the surface is taken known. Therefore, in this case, you can process the polyline with the calculated tool inclination angle.

You're a boss Man !!!! Thanks taking time to solve my problem:) It's possible send me the new .ard file ? after that i think i can work on this by myself... Did you use machine along spline or polyline stategy ??

All the best.

Julien.
