Settable work offsets
The labeling of the softkeys for the settable work offsets varies, i.e. the settable work offsets
configured on the machine are displayed (examples: G54...G57, G54...G505, G54...G599).
Please refer to the machine manufacturer's specifications.

Measuring a spigot

You have the option to measure and align rectangular spigots, and one or more circular
spigots.
Measuring a rectangular spigot
The rectangular spigot should be aligned at right-angles to the coordinate system. By
measuring four points at the spigot you can determine the length, width, and center point of
the spigot.
Please note that the straight lines between points P1 and P2 or P3 and P4 must intersect with
one another, in order that a measurement result is displayed.
Measuring one circular spigot
The workpiece is located anywhere on the work table and has a circular spigot. You can
determine the diameter and center point of the spigot with four measuring points.
Measuring two circular spigots
The workpiece is located anywhere on the work table and has 2 spigots. Four points are
automatically measured at the two spigots and the spigot centers are calculated from them.
The angle α is calculated from the connecting line between both center points and the reference
axis, and the new zero point that corresponds to the center point of the first spigot is determined.

Press the "Set WO" softkey.
The setpoint position of the center point is stored as a new zero point with
"Set WO". The tool radius is automatically included in the calculation.
