Cycle parameters
 Engraving text
QS500: Text to be engraved inside
quotation marks. Assignment of a string variable
through the Q key of the numerical keypad. The Q key
on the ASCI keyboard represents normal text input.
Allowed entry characters: See "Engraving system
variables" on page 319
 Character height Q513 (absolute): Height of the
characters to be engraved in mm. Input range 0 to
99999.9999
 Space factor
Q514: The font used is a proportional
font. Each character has its own width, which is
engraved correspondingly by the TNC if you program
Q514 = 0. If Q514 is not equal to 0, the TNC scales
the space between the characters. Input range 0 to
9.9999
 Font
Q515: Currently without function
 Text on a line/on an arc (0/1)
Q516:
Engrave the text in a straight line: Input = 0
Engrave the text on an arc: Input = 1
 Angle of rotation Q374: Center angle if the text is to
be arranged on an arc. Input range -360.0000 to
+360.0000°
 Radius of text on an arc
Q517 (absolute): Radius of
the arc in mm on which the TNC is to arrange the text.
Input range 0 to 99999.9999
 Feed rate for milling
Q207: Traversing speed of the
tool during engraving in mm/min. Input range 0 to
99999.999; alternatively FAUTO, FU or FZ
 Depth
Q201 (incremental value): Distance between
workpiece surface and engraving floor
 Feed rate for plunging Q206: Traversing speed of
the tool during plunging in mm/min. Input range 0 to
99999.999; alternatively FAUTO, FU
 Set-up clearance
Q200 (incremental): Distance
between tool tip and workpiece surface. Input range
0 to 99999.9999; alternatively PREDEF
 Workpiece surface coordinate
Q203 (absolute):
Coordinate of the workpiece surface. Input range
-99999.9999 to 99999.9999
 2nd set-up clearance Q204 (incremental): Coordinate
in the spindle axis at which no collision between tool
and workpiece (fixtures) can occur. Input range 0 to
99999.9999; alternatively PREDEF
