3D Scallop

The Scallop strategy is a finishing strategy which can be used for numerous high-quality finishing applications. Scallop generates a toolpath where the true offset between the passes along the surface of the geometry is kept constant. This ensures that the scallop height is kept constant across the entire surface, even in steep regions of the geometry.

Full Control Over all Parameters

Scallop supports rest machining and is ideal to for machining regions where previous strategies such as Contour or Parallel were not ideal, i.e. in regions with an intermediate slope or small corner radii. Scallop can of course also be used to finish an entire part. As with all strategies in HSM Performance Pack you have full control over the geometry selection and can use machine within angles to select appropriate regions of your geometry. You can freely configure the lead-in and lead-out moves of the operation. HSM Performance Pack generates lead arcs with optimal smoothness to minimize the tool wear. In addition, both the ramping and linking moves are freely configurable to match your tool, machine and part.

Constant Stepover

Note that Scallop differs from the Spiral operation in two ways: firstly it generates discrete passes with a constant offset between each pass, linked by smooth ramping motions, and not a continuous radial motion directed outward from a center. Secondly, the offset is calculated on the true 3D surface of the geometry and not in the 2D plane and subsequently projected. This means that stepover is maintained constant even in steep regions of the geometry.
