Note
On 2-axis machines, tool radius compensation is only possible in "real" planes, usually
with G18.
Tool length compensation
The wear parameter assigned to the diameter axis on tool selection can be defined as the
diameter value using an MD. This assignment is not automatically altered when the plane is
subsequently changed. To do this, the tool must be selected again after the plane change.
