Sinumerik Alarm 10769 Channel %1 block %2 Illegal surface normal vector with 3D tool radius compensation
Parameters:
%1 = Channel number
%2 = Block number, label
Definitions:
In 3D face milling, surface normal vector and path tangent vector must theoretically be perpendicular to one another, i.e. they must be at 90° to one another. Since both vectors can be programmed independently of each other, deviations from this angle are possible and allowed. This alarm is generated when the angle between surface normal vector and path tangent vector becomes less than the limit angle given by the machine data 21084 CUTCOM_PLANENORMAL_PATH_LIMIT.
Reactions:
– Local alarm reaction.
– Alarm display.
– Interface signals are set.
– Correction block is reorganized.
– NC Stop on alarm at block end.
Remedy:
Modify part program.
Program Continuation:
Clear alarm with NC START or RESET key and continue the program.
