- Override range
When a corner is determined to be an inner corner, the feedrate is
overridden before and after the inner corner. The distances Ls and Le,
where the feedrate is overridden, are distances from points on the cutter
center path to the corner (Fig.5.5.2 (b), Fig.5.5.2 (c)). Ls and Le are set
with parameter Nos. 6613 and 6614.
Fig.5.5.2 (b) Override Range (Straight Line to Straight Line)
When a programmed path consists of arcs, override is enabled for the
end point of a block if the distance is within Le. Similarly, override is
enable for the start point of a block if the distance is within Ls.
(Fig.5.5.2 (c)).
Fig.5.5.2 (c) Override Range (Arc to Arc)
Regarding program (2) of an arc, the feedrate is overridden from point a
to point b and from point c to point d (Fig.5.5.2 (d)).
