Programming the feed
FORI1
Feed for swiveling the orientation vector on the large circle
FORI2
Feed for the overlaid rotation around the swiveled orientation vector
With orientation movements the programmed feed
corresponds to an angle velocity
[
degrees/min
]
.
Effectiveness of feeds over G code:
When programming ORIAXES the feed for an
orientation axis can be limited by means of the
FL
[
]
instruction (feed limit).
When programming ORIVECT the feed must be
programmed with FORI1 or FORI2. FORI1 and
FORI2 may only be programmed once in the NC
block. When programmed in this manner, the path is
always traversed in the shortest way possible.
With overlaid turning and swiveling movements, the
smallest feedrate is always the one used. With
orientation movements the programmed feed
corresponds to an angle velocity [degrees/min].
If geometry axes and orientation axes are traversing
a path together, the traversing movement is
determined from the smallest feedrate.
