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.
Chamfer side length: Length of the chamfer; if
necessary:
Feed rate F (only effective in CHF block)
Example NC blocks
7 L X+0 Y+30 RL F300 M3
8 L X+40 IY+5
9 CHF 12 F250
10 L IX+5 Y+0
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.
