Measuring Cycles for Milling and Machining Centers5.6 CYCLE979 workpiece: Measure hole/shaft/groove/rib at an angleMeasuring cyclesProgramming Manual, 03/2009 Edition, 6FC5398-4BP10-2BA0 173Workpiece probe types that can be used● Multidirectional probe (_PRNUM=0xy)● Monodirectional, bidirectional probe (_PRNUM=1xy)When measuring contour elements hole, shaft, a 3- or 4-point measurementcan be used.Parameters for this selection are only set in this cycle, in the 4th digit of _PRNUM:_PRNUM=0zxy ⇒ 3-point measurement_PRNUM=1zxy ⇒ 4-point measurementThe 1st to 3rd digit of _PRNUM retains its significance depending on the illustration given inSection "Description of the most important defining parameters"!Note(_PRNUM) probes, which are calibrated with the calibration variant "Calibrate withcalculation of positional deviation", must be used in conjunction with CYCLE979.Exceptions: The probe is precision-adjusted mechanically and the positional deviation is lessthan +/-1 μm.ProgrammingCYCLE979Measuring variantsMeasuring cycle CYCLE979 permits the following measuring variants which are specified viaparameter _MVAR.Value Measuring variant1 Measure hole with tool offset2 Measure shaft with tool offset3 Measure groove with tool offset4 Measure web with tool offset101 ZO calculation in hole with ZO compensation102 ZO calculation on shaft with ZO compensation103 ZO calculation in groove with ZO compensation104 ZO calculation on web with ZO compensation
