Overview of Alarms
NCK alarms
Definitions: On inside corners, the path of the traversing blocks concerned is reduced but the orientation change
originally programmed in the block is retained and is now carried out in synchronism with the short-
ened path. Because of the ensuing changed relationship between path tangent, surface normal and
tool orientation, singular points or points with impermissible side angle can occur in 3D face milling.
This is not allowed.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10774 [Channel %1: ] Illegal tool dimensions with face cutting in block %2
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: This alarm occurs when illegal tool dimensions are programmed for face milling, e.g. negative tool
radius, rounding radius zero or negative for tool types that require a rounding radius, taper angle zero
or negative for tapered tools.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10775 [Channel %1: ] Illegal tool change with face cutting in block %2
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: This alarm occurs when a tool change has been programmed while 3D tool radius compensation is
active with the result that the tool type changes or, if the tool type remains unchanged, at least one
relevant tool dimension has changed as compared with the deselected tool. Depending on the tool
type, relevant tool dimensions can be the tool diameter, the rounding radius or the taper angle.
Changes to the tool length are allowed.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10776 [Channel %1: ] Block%2 axis %3 must be geometry axis if tool radius
compensation is active
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name
Definitions: This alarm occurs when an axis that is required for tool radius compensation is not a geometry axis.
With CUT2DF, the axis can be a positioning axis perpendicular to the machining plane; with all other
types of compensation (CUT2DF, CUT3DC, CUT3DF, CUT3DFF), all geometry axes must be oper-
ated as such.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
