Abbr. Inputs Dialog
TYPE Tool type: Press the ENT key to edit the field. The GOTO
key opens a window for selecting the tool type (in the tool
management, press the SELECT soft key to open a pop-up
window). You can assign tool types to specify the display
filter settings such that only the selected type is visible in
the table
Tool type?
DOC
Comment on tool (max. 32 characters)
Tool description
PLC
Information on this tool that is to be sent to the PLC
PLC status?
LCUTS
Tooth length of the tool for Cycles 22, 233, 256, 257
Tooth length in the tool axis?
ANGLE
Maximum plunge angle of the tool for reciprocating
plunge-cut in Cycles 22 and 208
Maximum plunge angle?
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: "Automatically retracting the tool
from the contour at an NC stop: M148", page 499
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 the Centering cycle
(Cycle 240) in order to calculate the centering depth from
the diameter entry
Point angle
PITCH
Thread pitch of the tool. Used by tapping cycles (Cycle
206, Cycle 207 and Cycle 209). A positive algebraic sign
means a right-hand thread.
Tool thread pitch?
AFC
Control setting for the adaptive feed control from the
AFC.TAB. In the tool table, press the SELECT soft key
to open the selection window (in the tool management,
press the SELECT soft key) and confirm the selection with
the OK soft key.
Input range: max. 10 characters
Feedback-control strategy
AFC-LOAD
Tool-dependent standard reference power for adaptive
feed control AFC.
The input in percent refers to the rated spindle power.
The control immediately uses the value given for regula-
tion, meaning a teach-in cut is dropped. The value should
be previously determined with a teach-in cut.
