Hi, it's me again. After more testing, unfortunately, I have to un-accept your answer @a.laasW8M6T.
At the time, it seemed like it was working, but more detailed analysis showed there were still deviations. Please see the attached file, where the machining path from Fusion is compared to other software, where surface normals can deviate up to 8 degrees alongside the uneven toolpath in my original post.
I am attaching another workpiece; please take a look if somebody can. I can't find the strategy or parameters to create straight machining toolpaths in Fusion 360 CAM software, and I think it's probably impossible.
Conditions for machining path:
- 5-axis machining with tool normal to the surface (Lead and lean option)
- the strategy must offer arbitrary machining direction selection
Currently, I am only able to create those paths with Steep and Shallow strategy but if there is another option that can create straight machining toolpaths under those conditions, I will gladly use it.
I want to get confirmation on why that happens. Mainly, I want to eliminate if I am doing something in the design that results in bad toolpaths or if this is because of the underlying Fusion path planning algorithm.
