Steep and Shallow Options dialog

Order — This determines the order in which the steep and shallow portions are machined.

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.

Note: As a general rule, use raster on open-edged parts and 3D offsets at the bottom of a pocket.
