SINUMERIK 808D ADVANCED alarms
3.2 NCK alarms
NC Stop on alarm at block end.
Remedy: Place deselection of the CRC such that the programmed end point comes to rest outside the compensation circle
around the last active compensation point. The following possibilities are available:
Deselection in the next block
Insert intermediate block
Select retract behavior NORM
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10757 [Channel %1: ] Block %2 Impermissible change of orientation while tool radius
compensation is active
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: An orientation change has been programmed which is not permissible with the tool radius compensation type (G code
of group 22). As a rule, changes to the tool orientation are only permissible and useful if 3D tool radius compensation
is active.
An (impermissible) orientation change can also be triggered by a change of machining plane (G17 - G19).
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Activate a G code from group 22, in which the programmed orientation change is permissible.
Execute the program with constant tool orientation.
If a plane change is necessary, first deactivate the tool radius compensation, and reactivate after the plane change.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10758 [Channel %1: ] Block %2 curvature radius with variable compensation value too small
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The current cutter radius compensation (the cutter used) is too large for the programmed path radius.
In a block with variable tool radius compensation, a compensation must be possible either anywhere or nowhere on
the contour with the smallest and the largest compensation value from the programmed range. There must be no point
on the contour in which the curvature radius is within the variable compensation range.
If the compensation value varies its sign within a block, both sides of the contour are checked, otherwise only the
compensation side.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Use smaller cutters or allow for a part of the cutter radius at the time of contour programming.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10759 [Channel %1: ] Block %2 path is parallel to tool orientation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In a block with spline or polynomial interpolation, the corrected path runs in at least one point parallel to the tool
orientation, i.e. the path has a tangent perpendicular to the compensation plane.
The tangent at a point on a path is regarded as parallel to the tool orientation if the angle between the two directions
is less than the limit value defined by MD21080 $MC_CUTCOM_PARALLEL_ORI_LIMIT.
However, in circumferential milling, straight lines running parallel to the tool orientation are permissible, as well as
circles with a circle plane perpendicular to the compensation plane (application with smooth retraction from the
groove).
Straight lines in the direction of the tool orientation are not permissible in face milling (CUT3D, CUT3DF, CUT3DFS).
