These additional characteristics make it possible to
program continuously smooth velocity characteristics
depending on the curvature of the workpiece to be
machined.
Sequence
FNORM
The feed address F defines the path feed as a
constant value according to DIN 66025.
Please refer to Programming Guide "Fundamentals"
for more detailed information on this subject.
Path
Feedrate
FLIN
The feed characteristic is approached linearly from
the current feed value to the programmed F value
until the end of the block.
