Limitation
- Next block
A block specifying chamfering or corner rounding must be followed by
a block that specifies a move command using linear interpolation (G01)
or circular interpolation (G02 or G03). If the next block does not
contain these specifications, alarm PS0431 is issued.
- Plane switching
A chamfering or corner rounding block can be inserted only for move
commands which are performed in the same plane. In a block that
comes immediately after plane switching (G17, G18, or G19 is
specified), neither chamfering nor corner rounding can be specified.
- Exceeding the move range
If the inserted chamfering or corner rounding block causes the tool to
go beyond the original interpolation move range, alarm PS0429 is
issued.
