Measuring Cycles for Turning Machines
6.5 CYCLE974 workpiece: 1-point measurement
Parameter
_OVI [5]
_OVI [6]
_OVI [7]
_OVI [8]
_OVI [9]
_OVI [11]
1) for workpiece measurement with tool offset only
2) For ZO correction only
3) from meas. cycles SW 6.3: For "tool offset" the offset value always appears in _OVR[20] as radius
dimension.
Starting positions for various measuring tasks
The starting positions before cycle call depend on the measuring task, the value of the
setpoint _SETVAL, the measuring axes, and the cutting edge position (SL) of the workpiece
probe.
The probe must be positioned facing the point to be measured and is reached by traversing
measuring axis _MA in the setpoint direction in the measuring cycle. The setpoint (position of
the point) is defined by parameter _SETVAL.
Measurement is possible parallel to and in the direction of the axes permitted by the "cutting
edge position" of the workpiece probe inserted.
