Often I have to use a small ball nose end mill to clean up the floor and walls of the pockets where the angle is < 90 deg.
Usually I would create a sketch of a line that is 5-10 deg. away from the wall and use it for my fixed tool axis orientation.
Then I would use "Multi-Axis Curve Machining", "Curve Machining Mode" – “Contact” or “Between curve and part”, and make several zig-zag passes toward the fillet.
I also sometimes would create a small surface and use Isoparametric Machining to achieve the desired tool path.
Also in some cases "Interpolation" works little better than "fixed axis" under "Tool axis mode", even though generally I try to avoid live 5 axis motions if possible.
A complex part may require creation of a lot of NC geometry, but that is what it takes to achieve a desired tool path.
I wonder if a Pencil MO could be used as a single operation to achieve everything that is mentioned above. However, I cannot find a way to control the angle of the cutter in relationship to all the walls.
I only want the tip of the ball nose to do the work, the shank of the tool needs to be a certain angle away from the wall (the wall should already be finished).
It would be nice if I could give it a range of a min/max angle between the walls and the cutter, and let Catia do the work.
Does anyone have ideas?
