Using the Z Work Offset Update Feature
If you would like to calibrate all your tools to a fixed Z axis location on
the machine, and then use the Z Axis Work Offset to shift all the tools
to the top of a part, you must use the G141 Edge Finding cycle with
Spindle Probing parameter updateTloOrWorkOffsetZAxis set to
WorkOffset. Only Q4, Q5, and Q6 cycle parameters will affect the
Z-axis.
 First, use Q6 to set the spindle probe tool length offset to the fixed
surface on the machine where all the tools are calibrated.
 Next, use Q4 or Q5 on the top of the work piece or to where you
want the Z zero to be located, to set the Z-axis work offset shift to
that Z position.
Both, the tool length offset and the G53 work offset must
be active before the Z part zero point will be correct. If
either one of these is not active at the same time, a
collision could occur.
