Working on the Pocket NC again, programming the final features that I've been putting off since the beginning.
The part that I'm working on has a flowy feature that connects two pocket holes (as seen in the image above). The difficulty is getting the ball endmill to finish up that face leaving a decent surface finish.
I started by just trying out a couple of the multi-axis toolpaths in Fusion360 without much success. I'm relatively new to 5-axis programming and have only done simple exterior features; I have not done anything like this, so I am not even sure really where to begin. I ended up just googling how to do it and found a helpful thread on the Autodesk forums talking about this specific issue; they even had a download for it.
I copied over the preset of the multi-axis program into my CAM setup and modified a few of the settings and generated it; I immediately got a very complicated jumble of toolpath going every direction possible. I simulated it, and just as expected, the tool crashed multiple times in the stock it was supposed to avoid and barely got any of the surfaces I selected. I ended up just restricting the endmill to a specific orientation and limited it to a maximum of 10deg tilt to prevent it from going on the other side. It turned out pretty decent, and the simulation shows it gets most of the material I wanted removing, there is one section toward the end where the side of the tool rubs up against the wall where I'm not super pleased with, but I'm sure I can figure that out.
