FS16/18/160/180-TC OPERATOR’S MANUAL
Modification of “Linear interpolation positioning”
B-62754EN/01-1
1 Application
This report is applied to following CNCs.
Series 16-TC
Series 18-TC
Series 160-TC
Series 180-TC
This report is a supplement for a following manual.
FANUC Series 16/18/160/180-TC
OPERATOR'S MANUAL
(B-62754EN/01)
2 Outline
In the above-mentioned manuals,
the explanation of “4.1 POSITIONING (G00) Linear interpolation positioning” is modified.
3 Details
The explanation of “4.1 POSITIONING (G00) Linear interpolation positioning” is replaced with
following explanation.
4.1 POSITIONING (G00)
Explanations
Linear interpolation positioning
The tool is positioned within the shortest possible time at a speed
that is not more than the rapid traverse rate for each axis. However,
the tool path is not the same as in linear interpolation (G01).
