The linear vectors are assigned to the specific vectors of the kinematics (I1, I2, etc.) in accordance
1)
with the normalizing process.
Result parameters _OVR[41] up to _OVR[59] are saved in groups of 3. The values include the
2)
measured actual values of the 3 linear axes (XYZ) in the machine coordinate system MCS.
At the start of the 1st measurement, the intermediate results (sphere center points) of the rotary axis are
deleted.
For 1st measurement, 1st rotary axis → Delete _OVR[41] ... _OVR[49]
For 1st measurement, 2nd rotary axis → Delete _OVR[51] ... _OVR[59]
Programming example
Note
The measuring program example can be analogously used for head and table kinematics. The
swivel data set must be appropriately adapted between marks SDA and SDE - and the rotary
axis names and rotary axis positions.
