ú Enter the coordinates of the end point for the line.
Further entries, if necessary:
ú Radius compensation RL/RR/R0
ú Feed rate F
ú Miscellaneous function M

The chamfer enables you to cut off corners at the intersection of
two straight lines.
■ The blocks before and after the CHF block must be in the same
working plane.
■ The radius compensation before and after the chamfer block must
be the same.
■ An inside chamfer must be large enough to accommodate the
current tool.
