Inserting a chamfer between two straight lines
The chamfer enables you to cut off corners at the intersection of two
straight lines.
„ The line blocks before and after the CHF block must be in the same
working plane as the chamfer
„ The radius compensation before and after the CHF block must be the
same
„ The chamfer must be machinable with the current tool
U Chamfer side length: Length of the chamfer, and if
necessary:
U Feed rate F (effective only in CHF block)

You cannot start a contour with a CHF block.
A chamfer is possible only in the working plane.
The corner point is cut off by the chamfer and is not part
of the contour.
A feed rate programmed in the CHF block is effective only
in that block. After the CHF block, the previous feed rate
becomes effective again.
