Order — This determines the order in which the steep and shallow portions are machined.
- Top first — Select this option to machine from the top regions downwards. If you have a boss, the shallow regions at the top of the boss are machined before the steep regions down the sides.
- Steep first — Select this option to machine the steep sections before the flat. If you have a boss, the steep regions are machined before the shallow regions.
Options
Threshold angle — Enter the angle of the surface slope, measured from the horizontal, that determines the split between constant Z (steep) and shallow machining.
Overlap distance — Enter the size of the overlap area between steep and shallow machining. This reduces marks on the model caused by a sudden switch between steep and shallow machining.
Steep
Spiral — Select this option to create a spiral path between two consecutive closed contours. This minimizes the number of lifts of the tool and maximizes cutting time while maintaining more constant load conditions and deflections on the tool.
Shallow
Select from:
Parallel
Optionally enter a Wall Clearance and Raster Angle.
3D Spiral
Smoothing — Select this option to smooth offsets of toolpath segments over the model.
