Cycle995 Measuring Cycle Parameters - Siemens SINUMERIK 840D sl Programming Manual

All default values = 0 or marked as the range of values a to b
1)
Display depends on the general SD54760 $SNS_MEA_FUNCTION_MASK_PIECE
2)
Intermediate positioning, circling around the ball at the equator
3)
Measure 3 balls: The same diameter setpoint applies for all three balls (_SETV)
4)
Default value for S_TNVL=1.2
5)
Correction in WO: Correction is only performed in the WO when the determined distortion is below the S_TNVL limit value.
If WO "fine" has not been set up in MDs, correction is according to WO "coarse"
6)
For measuring variant "Measure three balls", correction in a global basic frame is not possible (S_KNUM = 3001 to 3016),
7)
as the frame does not have a rotation component.

Meaning
Measuring variant (default=5)
Val‐ UNITS: Contour element
ues:
5 = Spindle geometry (parallel to the tool axis)
TENS: Repeat measurement
1 = with repeat measurement
HUNDREDS: No offset target
0 = measurement only
THOUSANDS: Measuring strategy
2 = measurement at an angle, align probe in direction of switching
TEN THOUSANDS: Number of spheres to be measured
0 = measure a sphere
HUNDRED THOUSANDS: Number of measurement points
1 = 4 measurement points when measuring at an angle (circle the sphere)
ONE MILLION: Determination of the diameter setpoint of the sphere
0 = No determination of the diameter setpoint of the sphere
1 = Determination of the diameter setpoint of the sphere
Correction target
0 = 0
Number of the field of the probe parameters (not probe number)
(value range 1 to 40)
Diameter of the calibration sphere
