Deselection of cutter radius compensation with G40 can only be performed in blocks
where the G function G00 (rapid traverse) or G01 (feed) is active.
In the block with G40, at least one axis in the plane G17 to G19 must be written. It is
always advisable to write both axes because, as a rule, both axes are traversed when
deselecting the compensation.
- Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Correct the NC program and put the compensation selection in a block with linear interpo-
lation.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 selection of the tool radius compensation via KONT not pos-
sible at the current starting point
%1 = Channel number
%2 = Block number, label
When activating the cutter radius compensation with KONT the starting point of the
approach block is within the compensation circle and therefore already violates the con-
tour.
If the cutter radius compensation is selected with G41/G42, the approach behavior
(NORM or KONT) determines the compensation movement if the present actual position
is behind the contour. With KONT, a circle is drawn with the cutter radius around the pro-
grammed initial point (= end point of the approach block). The tangent that passes
through the current actual position and does not violate the contour is the approach move-
ment.
If the start point is within the compensation circle around the target point, no tangent
passes through this point.
- Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Place selection of the CRC such that the starting point of the approach movements
comes to rest outside of the correction circle around the target point (programmed tra-
versing movements > compensation radius). The following possibilities are available:
• Selection in the previous block
• Insert intermediate block
• Select approach behavior NORM
Clear alarm with NC START or RESET key and continue the program.
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.
