13.FUNCTIONS TO SIMPLIFY PROGRAMMING PROGRAMMING B-63324EN/03
- 336 -
- Coordinate system
In a block that comes immediately after the coordinate system is
changed (G92, or G52 to G59) or a return to the reference position
(G28 to G30) is specified, neither chamfering nor corner rounding can
be specified.
- Travel distance 0
When two linear interpolation operations are performed, the
chamfering or corner rounding block is regarded as having a travel
distance of zero if the angle between the two straight lines is within
+/-1deg. When linear interpolation and circular interpolation
operations are performed, the corner rounding block is regarded as
having a travel distance of zero if the angle between the straight line
and the tangent to the arc at the intersection is within +/-1deg. When
two circular interpolation operations are performed, the corner
rounding block is regarded as having a travel distance of zero if the
angle between the tangents to the arcs at the intersection is within +/-
1deg.
- Single block operation
If a block in which chamfering or corner R is specified is executed in
single block mode, the block is executed up to the block end point, and
a feed hold stop occurs at the end point.
- Invalid command
Chamfering (, C) or corner R (, R) is ignored if it is specified in a block
that does not specify either linear interpolation (G01) or circular
interpolation (G02 or G03).
