08.96 3 Measuring Cycle Auxiliary Programs
3.2.4 L963 Auxiliary cycle for workpiece measuring cycle (external)
3.2.4 L963 Auxiliary cycle for workpiece measuring cycle (external)
This cycle is called by measuring cycle L979.
It is used to calculate circle parameters (X
m
, Y
m
and r) from 3 or 4 coordinates.
It is configured in a way to allow also direct calls to be made.
Parameter definition for L963:
R0 =6 5 4 3 2 1
m Input data from R parameter onwards
n Output data from R parameter
onwards
Output data:
R
n
Centrepoint abscissa
R

Execution time with 3 points depending on type of control up to approx. 3.5 s
4 points depending on type of control up to approx. 10 s
3.2.5 L964 Auxiliary cycle for workpiece measuring cycles (internal)
This cycle is called by cycles L973 and L976, when reference data are calibrated.
3.2.6 L965 Determination of measuring plane (external)
The cycle determines the axis data of the current plane and stores them internally. It must be
started at least once on completion of installation.
Programming also becomes necessary when the measuring plane is changed or the function
”Mirroring” has been activated or deactivated.
Transfer parameters: None
