Projection
For robotic plasma cutting, 3D CAD geometry is often drawn as a finished workpiece, with cutouts and other scrap excluded from the drawing. However, in plasma cutting, these scrap areas on a workpiece are used for pierces and lead-in entry motions, as well as lead-out exit motions.
In Robotmaster, the Projection option can be used to model (or “heal”) missing workpiece geometry in cutouts and other scrap areas that will be removed during cutting. This enables you to configure entry and exit motions relative to the actual physical geometry of the workpiece.
Projection can be used with the Normalize option for entry or exit to correctly model pierce points and other entry and exit geometry.
Disable
Robotmaster will not project surface geometry.Automatic
Tries the three techniques below and picks one automatically, if possible.Stock
Scrap CAD geometry must be imported and labeled as Stock in Robotmaster. With this option enabled, surface geometry can be projected onto stock.Untrim
Heal surfaces that have been trimmed and project onto the healed surface. This is designed for use with closed interior profiles.Extension
Project surface geometry outward at edges, as with exterior profiles.
Compensation type
Center
No kerf compensation will be used. The torch path will directly follow the toolpath with no left or right offset.
This option might be used with common line cutting or for open (non-closed) profiles that do not require kerf compensation.
Left
Left kerf compensation will be applied. When plasma cutting closed interior profiles, assuming a counterclockwise cut direction (when viewed from the top of the cut), a left kerf offset would correctly compensate the cut for kerf width.
Right
Right kerf compensation will be applied.
Use kerf radius as compensation
