5 Measuring Cycles for Milling Machines and Machining Centres 08.96
5.3 L979 Workpiece measurement hole/shaft/slot/web/ZO determination (at random angles)
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
• Bidirectional probe
• Monodirectional probe
The various types of probe and the number of measuring points are differentiated by defining
R22 (see Section 2.6)
R22 = 4 3 2 1
Probe number
0 Multidirectional probe
1 Monodirectional probe
0 3-point measurement
1 4-point measurement
An internal call of L963 is made by the cycle for calculation, parameter R00 is used for
defining L963. Depending on the type of control, cycle L963 takes up to approx. 0.5 to 10
seconds for the 4-point measurement!
