Cycle parameters

QS500 Engraving text?: 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", page 344
Q513 Character height? (absolute): Height of the
characters to be engraved in mm. Input range 0 to
99999.9999
Q514 Character spacing factor?: 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
Q515 Font?: Currently without function
Q516 Text on a line/on an arc(0/1)?:
Engrave the text in a straight line: Input = 0
Engrave the text on an arc: Input = 1
Engrave the text on an arc, circumferentially (not
necessarily legible from below): Input = 2
Q374 Angle of rotation?: Center angle if the text
is to be arranged on an arc. Engraving angle when
text is in a straight line. Input range -360.0000 to
+360.0000°
Q517 Radius of text on an arc? (absolute): Radius
of the arc in mm on which the TNC is to arrange
the text. Input range 0 to 99999.9999
Q207 Feed rate for milling?: Traversing speed of
the tool in mm/min while milling. Input range 0 to
99999.999 alternatively FAUTO, fu, FZ
Q201 Depth? (incremental): Distance between
workpiece surface and engraving floor
Q206 Feed rate for plunging?: Traversing speed
of the tool in mm/min while plunging. Input range
0 to 99999.999 alternatively FAUTO, fu
Q200 Set-up clearance? (incremental): Distance
between tool tip and workpiece surface. Input
range 0 to 99999.9999; alternatively PREDEF
