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 projecting pierces and lead-in entry motions, as well as / lead-out exit motionsmotion paths.

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 motion paths 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 /tool axis control vectors, as well as the rest of entry and exit geometrypaths.

...

• Disable
  Robotmaster will not project model (“heal”) cut-out 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 entry and exit paths will 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.

...

• 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 compensationoffset.

• Left
  Left kerf compensation will be applied. When For example, 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

Use the Kerf diameter value (kerf width) of the plasma cutting tool to calculate kerf compensation value. Robotmaster will use Kerf radius (Tool kerf diameter / 2) as the kerf offset distance.

Compensation offset

When Use kerf radius as compensation is disabled, you can enter a specific compensation offset value.

Kerf correction

Kerf correction is an option that allows the user to increase or decrease the radius/diameter of a hole by increasing or decreasing the offset of the plasma beam to the part’s edge. A positive Kerf correction will make a hole smaller. A negative Kerf correction will make a hole bigger, A Kerf correction of 0 will disable Kerf correction, resulting in a Kerf value imported from the Hypertherm cut chart being used.
