4.8 Milling cycles
Engraving, axial
The "Radial engraving" cycle engraves character strings in linear or
polar layout on the face of the workpiece. For character table and more
information, see page 335
You define the starting point of the character string in the cycle. If you
do not define a starting point, the cycle starts at the current tool
position.
You can also engrave a logotype with several calls. For this purpose,
specify the starting point with the first call. All other calls are
programmed without a starting point.
Parameters:
X Starting point (diameter dimension): Tool pre-positioning
Z Starting point: Tool pre-positioning
C Spindle angle: Workpiece spindle pre-positioning
TX Text to be engraved
NF Character number: ASCII code of the character to be engraved
Z2 End point Z position, infeed depth during engraving.
X1 Starting point (polar), first character
