Inserting a chamfer 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 G24 block must be in the same
working plane.
„ The radius compensation before and after the G24 block must be the
same.
„
The chamfer must be able to be machined with the current tool.

You cannot start a contour with a G24 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 G24 block is effective only
in that block. After the G24 block, the previous feed rate
becomes effective again.
