Redefine Measurement Around A Wcs Reference Frame (Measurement Type 18) - Siemens SINUMERIK 840D sl Function Manual

Redefine measurement around a WCS reference frame (measurement type 18)

Redefine WCS coordinate system ($AC_MEAS_TYPE = 18)
The zero point of the new WCS is determined by measuring point P1 at surface normal on
the oblique plane.
Figure 8-17
Measurement of plane
The plane is measured in one measuring cycle. The cycle records the three measuring
points and passes the necessary values to the variable interface.
The MEASURE() function calculates the solid angles and translational offset of the new
WCS' on the basis of the input values.
Transformation of measuring frame
The results of the calculation, i.e. the solid angles and translation, are entered in measuring
frame $AC_MEAS_FRAME. The measuring frame is transformed according to the selected
frame in the frame chain. The solid angles are also stored in the output values
$AC_MEAS_RESULTS[0..2]. In
● The angle around the abscissa of the old WCS is stored in $AC_MEAS_RESULTS[0],
● The angle around the ordinate is stored in $AC_MEAS_RESULTS[1] and
● The angle around the applicate is stored in $AC_MEAS_RESULTS[2].
