Sinumerik Alarm 10761 Channel %1 block %2 tool radius compensation for ellipse with more than one revolution not possible
Parameters:
%1 = Channel number
%2 = Block number, label
Definitions:
When machining the inside of an ellipse, in parts of the ellipse the curvature radii are greater than or smaller than the cutter radius compensation. In ellipses, in this case the block would be split up into 4 subblocks with curvature radii that are greater than and less than the compensation radius. Over several revolutions, there would be a tremendous increase in the amount of calculation required by the unlimited number of resulting subblocks, and therefore this situation is rejected by the error message. If compensation is possible everywhere or nowhere on the ellipse, then ellipses are also permissible that cover more than one full revolution.
Reactions:
– Local alarm reaction.
– Alarm display.
– Interface signals are set.
– Correction block is reorganized.
– NC Stop on alarm at block end.
Remedy:
Use cutter with smaller radius or program motion block on blocks with no more than one revolution.
Program Continuation:
Clear alarm with NC START or RESET key and continue the program.
