Use the Approach page to specify how the tool approaches the path.
If you have an Offset or Raster style selected, the Approach page has the following setting:
Add approaches from outside — Select to enable level moves to approach the model from outside the block.
If you have a Vortex style selected, the Approach page has additional options, which enable you to specify the helical ramp moves that are added to Vortex toolpaths to ensure the tool approaches the stock safely and does not plunge into the stock. Vortex adds these moves when the (linear/arc) approach outside moves (specified on the Leads and Links pages) would result in the tool plunging into the stock.
Helical Ramp — Specifies the size of the helix.
Max zig angle — Enter the angle of descent formed as the tool ramps into the block.
Circle Diameter (tool diameter unit) — Enter the diameter of the circle using tool diameter units (TDUs).
Height — Enter the height above the toolpath segment for the start of the ramp.
