Inserting A Chamfer Between Two Straight Lines - HEIDENHAIN ITNC 530 - CONVERSATIONAL PROGRAMMING User Manual

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)
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.
