Cycle parameters

Q10 Plunging depth? (incremental): Infeed per
cut. Input range -99999.9999 to 99999.9999
Q11 Feed rate for plunging?: Traversing speed
of the tool in the spindle axis. Input range 0 to
99999.9999, alternatively FAUTO, fu, FZ
Q12 Feed rate for roughing?: Traversing speed
of the tool in the working plane. Input range 0 to
99999.9999, alternatively FAUTO, fu, FZ
Q18 Coarse roughing tool? or QS18: Number or
name of the tool with which the TNC has already
coarse-roughed the contour. You are able to apply
the coarse roughing tool via soft key directly
from the tool table. In addition, you can enter
the tool name via the soft key tool name. 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. The
TNC will otherwise generate an error message.
Input range 0 to 99999 if a number is entered;
maximum 16 characters if a name is entered.
Q19 Feed rate for reciprocation?: Reciprocation
feed rate in mm/min. Input range 0 to 99999.9999,
alternatively FAUTO, fu, FZ
Q208 Feed rate for retraction?: 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
