Workpiece-Related Measuring/Calibrating; Data From The Following General Setting Data Are Used; ① Sd 54640 $Sns_Mea_Tpw_Trig_Minus_Dir_Ax1; ② Sd 54641 $Sns_Mea_Tpw_Trig_Plus_Dir_Ax1 - Siemens SINUMERIK 840D sl Programming Manual

● Workpiece-related measuring/calibrating:
Compensation strategy
The tool measuring cycle is intended for various applications:
● Initial measurement of a tool (general setting data SD 54762
● Post measuring a tool (general setting data SD 54762
Empirical values may optionally be included. A mean value is not calculated.

Note
Workpiece-related or machine-related measurement requires an appropriately
calibrated tool probe, see ChapterCalibrate probe (CYCLE971) (Page 202).
$SNS_MEA_FUNCTION_MASK_TOOL[Bit 9]):
The tool offset values in geometry and wear are replaced.
The offset is applied in the geometry component of the length or the radius.
The wear component is deleted.
$SNS_MEA_FUNCTION_MASK_TOOL[Bit9]):
The resulting difference is calculated into the wear component (links or radius) of the tool.
