Calibration, gauging block
Figure 1-5
A probe must be calibrated before it can be used. When being calibrated, the trigger points
(switching points), position deviation (skew), and precise ball radius of the workpiece probe
are determined and entered into the corresponding data fields of the general setting data
SD 54600 $SNS_MEA_WP_BALL_DIAM .
The default setting has data fields for 12 probes.
Calibration of the workpiece probe on turning machines is usually performed with gauging
blocks (reference grooves). The precise dimensions of the reference groove are known and
entered in the associated data fields of the following general setting data:
● SD54615 $SNS_MEA_CAL_EDGE_BASE_AX1
● SD54616 $SNS_MEA_CAL_EDGE_UPPER_AX1
● SD54617 $SNS_MEA_CAL_EDGE_PLUS_DIR_AX1
● SD54618 $SNS_MEA_CAL_EDGE_MINUS_DIR_AX1
● SD54619 $SNS_MEA_CAL_EDGE_BASE_AX2
● SD54620 $SNS_MEA_CAL_EDGE_UPPER_AX2
● SD54621 $SNS_MEA_CAL_EDGE_PLUS_DIR_AX2
● SD54622 $SNS_MEA_CAL_EDGE_MINUS_DIR_AX2
The default setting has data fields for three gauging blocks. In the measuring cycle program,
the selection is made using the number of the gauging block (S_CALNUM).
It is also possible to calibrate on a known surface.
Measuring cycle CYCLE973 with various measuring versions is ready for calibration.
