Cutting limits in X, Z
The tool position before the cycle call determines the effect of a
cutting limit. The Control machines the area to the right or to the left
of the cutting limit, depending on which side the tool has been
positioned before the cycle is called.
A cutting limit restricts the contour area that can be
machined; it does not apply to the paths for approach and
departure.
