Measuring tools for turning

Calibration data of the tool probe referred to the machine coordinate system
If you wish to calibrate the tool probe in the machine coordinate system, then the position of
the tool probe in the machine coordinate system must be entered into the following general
cycle setting data.
SD54625 $SNS_MEA_TP_TRIG_MINUS_DIR_AX1[k]
SD54626 $SNS_MEA_TP_TRIG_PLUS_DIR_AX1[k]
SD54627 $SNS_MEA_TP_TRIG_MINUS_DIR_AX2[k]
SD54628 $SNS_MEA_TP_TRIG_PLUS_DIR_AX2[k]
Calibration data of the tool probe referred to the workpiece coordinate system
If you wish to calibrate the tool probe in the workpiece coordinate system, then the position
of the tool probe in the workpiece coordinate system must be entered into the following
general cycle setting data. In this case, the reference point is the outer diameter or the tool
length of the active tool in the spindle.
Index [k] stands for the number of the actual data field (probe number -1).
SD54640 $SNS_MEA_TPW_TRIG_MINUS_DIR_AX1[k]
SD54641 $SNS_MEA_TPW_TRIG_PLUS_DIR_AX1[k]
SD54642 $SNS_MEA_TPW_TRIG_MINUS_DIR_AX2[k]
SD54643 $SNS_MEA_TPW_TRIG_PLUS_DIR_AX2[k]
Tool measurement using the "Orientable toolholder" or "Swivel tool" function
If the general cycle machine data MD52740 $MNS_MEA_FUNCTION_MASK, bit 16 = 1,
then the following setting applies:
MD51618 $MNS_MEA_CM_ROT_AX_POS_TOL
= 0,5
The real angular position of rotary axes can deviate from that programmed (exact stop fine
window) This deviation depends on the position control properties of the axis. The maximum
deviation that can be expected at a specific axis should be entered into the parameter. When
the tolerance is exceeded, Alarm 61442 is output - "Toolholder not parallel to the geometry
axes".
