Parameter Meaning Dialog
NMAX
Limit the spindle speed for this tool. The programmed
value is monitored (error message) as well as an increase
in the shaft speed via the potentiometer. Function inactive:
Enter
–
.
Input range : 0 to +999 999; if function not active: enter
–
Maximum speed [rpm]
LIFTOFF
Definition of whether the control should retract the tool in
the direction of the positive tool axis at an NC stop in order
to avoid leaving dwell marks on the contour. If
Y
is defined,
the control retracts the tool from the contour, provided
M148
has been activated.
Further information: "Lifting off the tool automatically from
the contour at NC stop: M148", Page 310
Retract allowed? Yes=ENT/
No=NOENT
TP_NO
Reference to the number of the touch probe in the touch-
probe table
Number of the touch probe
T-ANGLE
Point angle of the tool. Is used by Cycle
240
in order to
calculate the centering depth from the diameter input
Point angle
PITCH
Thread pitch of the tool. Is used by Cycles
206
,
207
, and
208
. A positive algebraic sign means a right-hand thread.
Tool thread pitch?
LAST_USE
Time of last tool presence in the spindle
Date/time of last tool call
PTYP
Tool type for evaluation in the pocket table
Refer to your machine manual. Function is defined by the
machine manufacturer!
Tool type for pocket table?
ACC
Activate or deactivate active chatter control for the respec-
tive tool (Page 312).
Input range : N (inactive) and Y (active)
ACC active? Yes=ENT/No=NOENT
KINEMATIC
Use the
SELECT
soft key to show the tool carrier kinemat-
ics. In the tool management, use the
SELECT
soft key and
the
OK
soft key to adopt the file name and the path

Tool-carrier kinematics
OVRTIME
Time for exceeding the tool life in minutes
Further information: "Overtime for tool life", Page 145
Refer to your machine manual. Function is defined by the
machine tool builder!
Tool life expired
RCUTS
Front-face cutting width of the tool (e.g., for indexable
inserts)
Entering a value here influences helical and reciprocating
plunging in Cycles
251
,
252
, and OCM.
Further information: User's Manual for Programming of
Machining Cycles
Width of the indexable insert
LU
Usable length of the tool for drilling cycles and Cycles
25x
By entering a value here, you can limit the plunging depth in
the cycles.
If used in conjunction with
RN
, then
LU
may also be greater
than
LCUTS
.
Usable length of the tool?
RN
Neck radius for the exact definition of the tool for graphic
simulation (e.g., neck of end mills or side milling cutters)
A neck radius
RN
that is shown in the graphic simulation is
possible only if
LU
>
LCUTS
.
Neck radius of the tool?
