working plane.
• The radius compensation before and after the chamfer block must
bethe same.
• An inside chamfer must be large enough to accommodate the
currenttool.
• You cannot start a contour with a chamfer 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.
