Morphed Spiral milling strategy

The Morphed Spiral toolpath can be used for semi finishing and finishing. It can be very useful when machining free-form/organic surfaces. This path is very similar to the Spiral strategy.

The cut pattern is based on the outer boundary of the stock or the selected containment boundary. The passes are calculated from a top view of the working plane and then projected down to the surface. This makes it less useful for steep or vertical surfaces.

The Stepover parameter controls the cut distance between rows. Use the Inside/Outside Direction parameters to control the order of the cuts and the Clockwise parameter to control the spiral direction.

Controls exist for containing the toolpath to a specific area. You can use Machining Boundaries to contain the machining area in X & Y and the Heights parameters to contain the machining areas in Z. As a default, it will assume you want to machine the entire model. The Contact Point Boundary parameter is useful for extending the toolpath to the edges of the boundary or surface.
