Detailed Description
2.4 Tool radius compensation 2D (TRC)
Basic logic functions: Tool Offset (W1)
Function Manual, 11/2006, 6FC5397-0BP10-2BA0
89
The type of contour suppression is evaluated only in the first traversing block of a
sequence of consecutive traversing blocks.
If both CUTCONON and G41 or G42 are programmed in the first block, the response to
deactivating contour suppression is determined by CUTCONON.
Changing from G41 to G42 or vice versa makes sense in this case as a means of
changing the compensation side (left or right of the contour) when restarting.
A change of compensation side (G41/G42) can also be programmed in a later block, even
if contour suppression is active.
Collision detection and bottleneck detection is deactivated for all blocks with active
contour suppression.
2.4.11 Alarm behavior
Alarm during preprocessing
If a tool radius compensation alarm is output during preprocessing, main-run machining
stops at the next block end reached, i.e., usually at the end of the block currently being
interpolated (if Look Ahead is active, once the axes have come to a stop).
Alarms for preprocessing stop and active tool radius compensation
Tool radius compensation generally requires at least one of the following traversing blocks
(even more for bottlenecks) to determine the end point of a block. Since the preprocessing
stop of such a block is not available, traversing continues to the offset point in the last block.
Correspondingly, the offset point in the start point is approached in the first block after a
preprocessing stop.
The contour obtained may deviate considerably from the one that would result without
preprocessing stop. Contour violations in particular are possible. Therefore the following
setting data was introduced:
SD42480 $MC_STOP_CUTCOM_STOPRE (alarm response for TRC and preprocessing
stop).
The response of the tool radius compensation remains unchanged compared to the previous
status, and/or an alarm is output for preprocessing stop during active tool radius
compensation and the program is halted, depending on the value.
The user can acknowledge this alarm and continue the NC program with NC start or abort it
with RESET.
