Channel %1 block %2 deselection of the tool radius compensation via KONT not
possible at the programmed end point
%1 = Channel number
%2 = Block number, label
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.
- Local alarm reaction.
- Alarm display.
- Interface signals are set.
- Correction block is reorganized.
- NC Stop on alarm at block end.
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 possibil-
ities are available:
• Deselection in the next block
• Insert intermediate block
• Select retract behavior NORM
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 changing the compensation plane while tool radius compen-
sation is active not possible
%1 = Channel number
%2 = Block number, label
In order to change the compensation plane (G17, G18 or G19) it is first necessary to
deselect the cutter radius compensation with G40.
- Local alarm reaction.
- Alarm display.
- Interface signals are set.
- Correction block is reorganized.
- NC Stop on alarm at block end.
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.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 curvature radius with variable compensation value too small
%1 = Channel number
%2 = Block number, label
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.
