Second example
Measuring workpieces in swiveled states. The workpiece is to be probed in the X direction
even though the probe cannot approach the workpiece in the X direction because of an
obstructing edge (e.g. due to clamping elements). However, with a swivel movement, the
measurement in the X direction can be replaced by a measurement in the Z direction.

Setting the edge

The workpiece lies parallel to the coordinate system on the work table. You measure one
reference point in one of the axes (X, Y, Z).

Prerequisite
You can insert any tool in the spindle for scratching when measuring the workpiece zero
manually.
66
Apply "Set zero plane" to store the resulting rotations in the work zero.
Apply "Align plane" to correct the alignment of the workpiece.
Apply "2 holes" to define the rotation and offset in the XY plane.
Apply "Set edge Z" to define the offset in Z.
Start the program with swivel zero.
Load the probe and activate the desired work offset.
With "direct" swiveling enter the required rotary axis positions or with "axis by axis" the
required rotations (e.g. Y=-90) and <CYCLE START>.
Apply "Set edge Z": The measured offset in Z is converted and entered as an X value in
the chosen work offset.
