Engraving on Flat and Complex Surfaces

Engraving NC sequences are generally created by the tool
following a curve or a Groove cosmetic feature. The tool
diameter determines the width of cut.
Engraving:
• Flat or Complex Surfaces
• Use Cosmetic Groove or Curve
features
• For logos or part numbers

Engraving NC sequences are generally created by the tool following a curve
or a Groove cosmetic feature. The tool diameter determines the width of
cut, and the GROOVE_DEPTH parameter determines the depth of cut. You
can perform engraving in multiple step increments if you set the parameter
STEP_DEPTH to a value that is smaller than the value of GROOVE_DEPTH.
You can also select multiple Groove features or curves to be machined within
a single engraving NC sequence.
For 3-Axis engraving, there are two ways to specify the tool trajectory:
• By selecting a reference Groove feature to follow.
• By selecting one or more curves to follow. The current tool axis is used to
drive the tool along the curve. You can select the curve individually in the
graphics window or from the Model Tree.
Parameters
• GROOVE_DEPTH – This parameter sets the depth of the engraved feature
and is measured from the surface. A positive value is specified for this
parameter.
• STEP_DEPTH – This parameter is used to set the maximum depth the
tool will take per each pass.
• CUT_FEED – This parameter is used for cutting speed, normally slower
because a much smaller tool is used.
• SPINDLE_SPEED – This parameter sets the RPMs for the cutter, usually
higher than normal, to keep the chip load down for smaller tools.
