Inserting a chamfer CHF between two straight
lines
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.
(The tool radius in the illustration at bottom right is too large)

You cannot start a contour with a CHF block.
A chamfer is possible only in the working plane.
The feed rate for chamfering is the same as for the
preceding block.
The corner point E is cut off by the chamfer and is not
part of the contour.
