L977 Workpiece Measurement Hole/Shaft/Slots/Zo Determination (Paraxial) - Siemens SINUMERIK 840 User Manual

5 Measuring Cycles for Milling Machines and Machining Centres

5.2 L977 Workpiece measurement hole/shaft/slots/ZO determination (paraxial)

5.2 L977 Workpiece measurement hole/shaft/slots/ZO
determination (paraxial)
The cycle determines the dimensions of holes, shafts and slots (H-S-S measuring cycle) and
performs automatic tool offset when necessary.
It also determines the zero offset (ZO) between the centre point of a hole, shaft or slot and the
workpiece zero point.
For measuring variants hole and shaft, measurements can be performed with active coordinate
rotation (see MDC 7004.1).
Selection is performed on the basis of the definition of R23:
Definition of R23
R23= 1 Measure hole with
tool offset
R23= 2 Measure shaft with
tool offset
R23= 11 Measure slot with
tool offset
R23= 12 Measure web with
tool offset
R23= 21 ZO determination in hole with
correction of the zero offset
R23= 22 ZO determination at shaft with
correction of the zero offset
R23= 31 ZO determination in slot with
correction of the zero offset
R23= 32 ZO determination at web with
correction of the zero offset
Applicable types of probe: (see Section 1.3)
• In the case of milling and machining centres the probe must be entered as type 30 in the
TOA memory.
•
Multidirectional probe
•
Monodirectional probe
• Bidirectional probe
A distinction is made between the probe types by defining R22 (see Section 2.6).
