Measurement for defining an additive rotation for taper turning (measurement type 28)

Taper turning
Additive rotation of plane ($AC_MEAS_TYPE = 28)
This measurement type 28 is used via the ManualTurn Advanced user interface for the taper
turning application. An additive rotation of the active (or a certain) plane around an angle in
the range of α = +/- 90° can be specified with it. The rotation takes place on the coordinate
axis at right angles to the plane.

Application
With taper turning, the active plane is rotated by the taper angle, whereby the rotation is
written in the active cycle frame. With RESET, the cycle frame is deleted. Re-activation may
be necessary. The selection of the cycle frame is made depending on the SZS position
display. If after activation of the rotation, e.g. with active plane G18, traversing is performed
in the direction of z', the actual positions of the corresponding axes change simultaneously
for x and z
Rotations with active planes G17 and G18 behave in the same way and are displayed in the
above figure. The values of the following variables are evaluated for measurement type 28:
Input variable
$AC_MEAS_VALID
$AC_MEAS_WP_SETANGLE
$AC_MEAS_ACT_PLANE
$AC_MEAS_FRAME_SELECT
$AC_MEAS_INPUT[0]
$AC_MEAS_TYPE
