Sinumerik Alarm 10773 Channel %1 illegal tool orientation in block %2 at inside corner with block %3

Sinumerik Alarm 10773 Channel %1 illegal tool orientation in block %2 at inside corner with block %3

Parameters:
%1 = Channel number
%2 = Block number, label
%3 = Block number, label

Definitions:
On inside corners, the path of the traversing blocks concerned is reduced but the orientation change originally programmed in the block is retained and is now carried out in synchronism with the shortened path. Because of the ensuing changed relationship between path tangent, surface normal and tool orientation, singular points or points with impermissible side angle can occur in 3D face milling. This is not allowed.

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
