I'm looking to cut an aluminum mold with pockets nearly 3" deep. Try as I might, I'm not finding narrower endmills to perform a finishing pass long enough for this.
I'm starting to think now that the way to do this is to not have a finishing pass, but to use the full size endmill for the entire cut. So I'd have to find a CAM setting to have the mill follow the path of the wall, to get a smooth finish on it.
Is this a good approach to the problem? Anyone know the setting to get this style of toolpath out of VCarve Pro or Cut3D?
