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"
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 in a straight line/on arc (0/1) Q516:
Engrave text in a straight line: Input = 0
Engrave 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 in mm/min while milling. Input range 0 to
99999.999 alternatively
FAUTO, FU, FZ
Depth Q201 (incremental value): Distance between
workpiece surface and engraving floor
Feed rate for plunging Q206: Traversing speed
of the tool when moving into the workpiece 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
Coordinate of workpiece surface 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
