 Plunging depth Q10 (incremental value): Dimension
by which the tool plunges in each infeed.
 Feed rate for plunging Q11: Traversing speed of the
tool in mm/min during penetration.
 Feed rate for roughing Q12: Traversing speed for
milling in mm/min.
 Coarse roughing tool Q18 or QS18: Number or name
of the tool with which the TNC has already coarse-
roughed the contour. Switch to name input: Press the
TOOL NAME soft key. 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 (see “Tool Data,” page 198), and
define the maximum plunging ANGLE of the tool. The
TNC will otherwise generate an error message.
 Reciprocation feed rate Q19: Traversing speed of
the tool in mm/min during reciprocating plunge-cut.
 Retraction feed rate Q208: Traversing speed of the
tool in mm/min when retracting after machining. If
you enter Q208 = 0, the TNC retracts the tool at the
feed rate in Q12.
