The standard log header is used.
A user-defined log header is used.
When measuring milling tools with the spindle rotating, the measuring cycle
calculates the feed and speed.
The user enters the feed and speed in data field (data array) _MFS[ ].
No deletion
For the following measuring cycle call, the data fields (data arrays) _TP[ ], _TPW[
], _WP[ ], _KB[ ], _EV[ ], _MV[ ] and _CBIT[13] are set to zero.
The length 1 of the measuring probe referred to the center of the probe sphere
(ball) should be entered into the tool offset..
The length 1 of the measuring probe referred to the circumference of the probe
sphere (ball) should be entered into the tool offset..
No transfer
When using the "Calibrate with probe sphere calculation" measurement variant,
the determined "effective probe sphere diameter" (_WP[k,0]) converted as a
radius value, is entered into the radius geometry memory of the active workpiece
measuring probe as the tool offset.
No calibration monitoring
Calibration monitoring active
The monitoring checks whether the calibration plane, mono/multi probe
calibration or calibration at the probe center point/probe end point between
calibrating and measuring is identical.
Note:
When measuring cycles are called up from "Measuring in JOG" or "ShopMill",
these monitoring checks are always active and cannot be deactivated.
