10756 Channel %1 block %2 deselection of the tool radius compensation via
KONT not possible at the programmed end point
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: On deselection of the cutter radius compensation, the programmed end point is within the
compensation circle. If this point were in fact to be approached without compensation, there would be
a contour violation.
If the cutter radius compensation is deselected via G40, the approach behavior (NORM or KONT)
determines the compensation movement if the programmed end point is behind the contour. With
KONT, a circle is drawn with the cutter radius about the last point at which the compensation is still
active. The tangent passing through the programmed end position and not violating the contour is the
retraction movement.
If the start point is within the compensation circle around the target point, no tangent passes through
this point.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
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 changing the compensation plane while tool
radius compensation is active not possible
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In order to change the compensation plane (G17, G18 or G19) it is first necessary to deselect the
cutter radius compensation with G40.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Insert an intermediate block in the part program using the correction deselection. After the plane
change, the cutter radius compensation is to be selected in an approach block with linear interpolation.
Program Clear alarm with NC START or RESET key and continue the program.
