Programming
FENDNORM
G62 G41
or
G621
Parameters
FENDNORM Automatic corner deceleration OFF
G62 Corner deceleration at inside corners
when tool radius offset is active
G621 Corner deceleration at all corners
when tool radius offset is active
G62 only applies to inside corners with
• active tool radius offset G41, G42 and
• active continuous-path control mode G64, G641
The corner is approached at a reduced feed rate resulting from:
F * (override for feed rate reduction) * feed rate override
The maximum possible feed rate reduction is attained at the precise point where the tool is
to change directions at the corner, with reference to the center path.
G621 applies analogously with G62 at each corner, of the axes defined by FGROUP.
