Only relevant for calibration in two axis directions

Only measuring axis and measuring direction are determined automatically from the cutting edge position (SL) of the

probe. SL=8 → -X , SL=7 → -Z
The number of the calibration groove (n) refers to the following general setting data (all positions in machine coordinate

system):
For cutting edge SL=7:
SD54615 $SNS_MEA_CAL_EDGE_BASE_AX1[n] Position of the base of the groove in the 1st axis of plane (for G18 Z)
SD54621 $SNS_MEA_CAL_EDGE_PLUS_DIR_AX2[n] Position of the groove wall in the positive direction of the 2nd
axis of the plane (for G18 X)
SD54622 $SNS_MEA_CAL_EDGE_MINUS_DIR_AX2[n] Position of the groove wall in the negative direction of the 2nd
axis of the plane
For cutting edge SL=8:
SD54619 $SNS_MEA_CAL_EDGE_BASE_AX2[n] Position of the base of the groove in the 2nd axis of the plane
SD54620 $SNS_MEA_CAL_EDGE_UPPER_AX2[n] Position of the upper edge of the groove in the 2nd axis of the
plane, (only to pre-position the probe)
SD54617 $SNS_MEA_CAL_EDGE_PLUS_DIR_AX1[n] Position of the groove wall in the positive direction of the 1st
axis of the plane
SD54618 $SNS_MEA_CAL_EDGE_MINUS_DIR_AX1[n] Position of the groove wall in the negative direction of the 1st
axis of the plane
Note:
The position values for the groove wall +- can be roughly determined.
The slot width from the difference of the position values of the groove wall must be able to be precisely determined
(precision dial gauge).
When calibrating in the groove, it is assumed that the tool length of the probe of the calibrated axis = 0.
The position values for the groove base must also be precisely determined at the machine (not a dimension drawing).
