I'm cutting a 3d file that is creating a sloped rabet in a door frame. To cut this I'm using an end mill, not a ball end.
I understand that when I use a BALL mill I have to offset to the outside of my model in order to have the diameter of the ballnose cut fully to the edge of the 3d model.
Is this also true of an end mill? In other words, is the outside EDGE of an endmill used to compute the 3D path, or the center, as with a ball nose bit?
Along that same idea, does Artcam compute its 3D path assuming a ball nose geometry, or does it change its computation based on bit geometry?
Knowing this would help me write better toolpaths, I'm thinking.
