4 Measuring Cycles for Turning Machines 08.96
4.1 L972/L982 Tool measurement
4.1 L972/L982 Tool measurement
Tool cycles with the following functions are available for tool measurement:
• L972 – Calibrate tool probe
– Measure tool of L1 or L2 with tool types 1 ... 10, 26, 28,
31 ... 38 with one tool offset number
– Automatic tool measurement of L1 and/or L2 with tool types
1 ... 10, 26, 28, 31 ... 38 with one tool offset number
• L982 – All functions of L972
– Automatic tool measurement of L1 and/or L2 and R
with tool types 28, 37, 38
with one or two tool offset numbers.
Selection: Length and/or radius compensation
Cycle L982 needs approx. 45 % more memory space than L972 and its running time is
approx. 20 % slower.
The 3rd and 4th decimal place of R23 are additionally used for coding the measurement
variant of L982.
R23=4321
0 Measurement also automatically of L1and/or L2
with tool types 1 ... 10, 26, 28, 31 ... 38 with
one tool offset number
1 Measurement also automatically of L1 and/or L2
and R
with tool types 28, 37, 38 with
one tool offset number
2 Measurement also automatically of L1 and/or L2
and R
with tool types 28, 37, 38 with
two tool offset numbers
0 Compensate length and radius
1 Compensate length only
2 Compensate radius only

With Version 3.2 and higher cycle L972 is available in two versions:
• L972-1 – Calibrate tool probe
– Tool measurement of L1 or L2 with tool types 1 ... 8,
PF-PF (basic function) also automatically
• L972-2 – Calibrate tool probe
– Tool measurement of L1 or L2 with tool types 1 ... 10
– also PF-SF; SF-SF for tool types 1 ... 8 also automatically
– mirrored measurement
– SF-SF for type 9 only
Cycle L982 is also available in two versions with Version 3.2 and higher:
• L982-1 – Tool measurement type 30-39 (basic functions)
• L982-2 – Tool measurement type 20-39 and mirrored measuring.
The version that you require must be loaded in the part program memory and/or linked into the
user memory submodule.
