Chamfer G24
TNC 360
The chamfer function permits you to cut off corners at the intersection of
two straight lines.
You enter the length L to be removed from each side of the corner.
Prerequisites:
• 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.
• You cannot start a contour with a G24 block.
• A chamfer is only possible in the working plane.
• The feed rate for chamfering is taken from the previous block.
• The corner point E is cut off by the chamfer and is not part of the resulting contour.
