swarf conture programming

[tom.frankee1991]

Hello everyone,

I would like to know which approach you would choose for milling such a spiral as shown in the attachments.  It is a "wood braid" that I have already programmed in B-Solid (Biesse Rover) using only contours, which was pretty easy. However, in Fusion, I don't know how to achieve my goal except by "selecting surfaces." and then it generates automaticaly milling operations. It is important to me that I can guide the cutter precisely along the contours, as a specific form cutter is being used for this project. Ive already tried some 5 axis operations but its not working. The dxf file of the 3D splines is attached. Would be very helpful if someone can make a screencast or just preparing an example of fusion file 

Here is a video of an advanced wood braid

Thank you in advance (:

Hi

To drive a Swarf toolpath you would need a top and bottom guide curve, the attached .dxf only has one (Top?)curve there is nothing to select for a bottom drive curve to define the swarf "Ruled Surface"

[tom.frankee1991]

That's correct, there are only top lines in the DXF file. I know the method with top/bottom contours, but I programmed it in B Solid with just one contour where the cutter runs perpendicular to the contour— that was very simple. I would like to know how to do it in Fusion. Which milling strategy would you recommend?

Hi

In Fusion there is also Multiaxis contour, but it needs surfaces to determine the normal direction for the tool axis.

When you Create the toolpath in B Solid you say it keeps the tool normal to the contour but there are infinite solutions for where normal is on a line, it must have some other method of defining the tool axis, unless I'm missing something?

For the type of machining you are wanting to do the Swarf toolpath in Fusion is most appropriate but it needs surfaces or pairs of drive curves
