Cycle parameters
 Plunging depth Q10 (incremental): Infeed per cut.
Input range -99999.9999 to 99999.9999
 Feed rate for plunging Q11: Traversing speed of the
tool in mm/min during plunging. Input range 0 to
99999.9999; alternatively FAUTO, FU, FZ
 Feed rate for roughing Q12: Traversing speed of the
tool in mm/min during milling. Input range 0 to
99999.9999; alternatively FAUTO, FU, FZ
 Coarse roughing tool Q18 or QS18: Number or name
of the tool with which the TNC has already coarse-
roughed the contour. Press the TOOL NAME soft key
to switch to name input. The TNC automatically
inserts the closing quotation mark when you exit the
input field. If there was no coarse roughing, enter "0";
if you enter a number or a name, the TNC will only
rough-out the portion that could not be machined with
the coarse roughing tool. If the portion that is to be
roughed cannot be approached from the side, the
TNC will mill in a reciprocating plunge-cut; for this
purpose you must enter the tool length LCUTS in the
tool table TOOL.T and define the maximum plunging
ANGLE
of the tool. Otherwise, the TNC will display an
error message. Input range 0 to 32767.9 if a number
is entered; maximum 32 characters if a name is
entered.
 Reciprocation feed rate Q19: Traversing speed of
the tool in mm/min during reciprocating plunge-cut.
Input range 0 to 99999.9999; alternatively FAUTO, FU,
FZ
 Feed rate for retraction Q208: Traversing speed of
the tool in mm/min when retracting after the
machining operation. If you enter Q208 = 0, the TNC
retracts the tool at the feed rate Q12. Input range 0 to
99999.9999; alternatively FMAX, FAUTO, PREDEF
