The 5 axis Drive Curve Cut uses 3D driving curves to calculate the tool path. The cutter is driven along these curves and respects the surface geometry to be cut. This operation shares the same Axis Control capability as the 5 Axis Plane Cut operation.
Each 5 axis Guide Surface Iso Cut operation must have drive surface(s) selected in its feature list with general surfaces input as the cutting target. The guide surface defined by a drive surface forces tool axis to follow its normals along the isolines.
The offset 3D cut operation is used when a smooth and continuous tool path is required in the vicinity of steep walls, milling in uncut or uncutable places or when milling the entirely part as a whole.
The drive curve cut operation is similar to the offset 3D cut that starts from a custom set of curves. The starting curves can be open or closed. In general it is used like the flowing cut for milling along features.
