10.3.10 Clamping system: Clamping time statistics
This window displays the statistics for the determined clamping times.
Statistical data Meaning
Last determined clamping time Measured time for the last performed clamping operation.
Definition of a clamping operation: "Released" clamping state
[3] → "Clamped with tool" clamping state [7 or 8]. Clamping state
3 = Released; clamping state 7 = Clamped with tool and S4 = 0
(No); clamping state 8 = Clamped with tool and S4 = 1 (Yes)
Reference clamping time (with tool) During the spindle start-up phase, the first 100 clamping opera‐
tions are measured by the SMI24 and the minimum value, max‐
imum value and the mean value determined.
● Minimum
The shortest clamping time determined from the first maximum
100 clamping operations.
● Maximum
The longest clamping time determined from the first maximum
100 clamping operations.
● Mean
The mean clamping time determined from the first maximum
100 clamping operations.
Mean clamping time (without tool) After the first 100 clamping times determined for the reference
time, the mean values for the other measured clamping times
are calculated.
● 24 h
Mean clamping time of the clamping cycles determined in the
last 24 hours.
● 10 days
Mean clamping time of the clamping cycles determined in the
last 10 days.
● 100 days
Mean clamping time of the clamping cycles determined in the
last 100 days.
If a Power On of the SMI24 is performed during the start-up phase, the previously determined
values are discarded. The counter for the first 100 clamping operations is set to zero and the
reference times up to the 100th clamping operation can be determined again. After the start-
up phase (first 100 clamping operations), the values of the reference clamping time are
"frozen". Even after a Power On of the SMI24, the values remain stored and can no longer be
changed.
