Fagor alarm 1005: Chamfer programmed wrong.
CNC 8055 CNC error · Fagor 8055/8055i
What it means
The path that follows a chamfer definition (G39) is a circular arc. Chamfers can only be blended between paths where the following move is straight, so block preparation fails and the program stops.
Likely causes
- arc programmed immediately after the G39 chamfer block
- chamfer intended for a line-line corner but applied at a line-arc corner
