Meaning
FENDNORM
G62
G621
G62 only applies to inside corners with
● active tool radius offset
● active continuous-path mode
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
4.11 Programmable end of motion criteria (FINEA, COARSEA,
IPOENDA, IPOBRKA, ADISPOSA)
Function
Similar to the block change criterion for path interpolation (G601, G602, and G603) it is also
possible to program the end-of-motion criterion for singleaxis interpolation in a part program
or in synchronized actions for command/PLC axes.
The end-of-motion criterion set will affect how quickly or slowly part program blocks and
technology cycle blocks with singleaxis movements are completed. The same applies for
PLC via FC15/16/18.
