STYLUS TIP DIAMETER CALIBRATION PROCEDURE:
STEP 1:
On the mill table, fixture the precision ring gauge from the probe tool kit. The ring must
lie flat with the center line of the bore aligned with the center line of the probe stylus. Note the
diameter of the gauge.
STEP 2:
Jog the probe over the center (roughly) of the ring gauge, and then slowly jog the Z-axis
down until the tip of the probe is inside the bore and not touching anything.
STEP 3:
From the main screen, press <F1-Setup>, then <F1-part>, then <F5-Probing>, Enter
0.00 in the field provided for probe stylus diameter and press enter, then <F1-Bore>,and finally <Cycle
Start>. The control will probe opposing walls of the bore then stop in the center of the bore. A
message box will appear on the screen that will display the measured diameter of the bore. Subtract
this number from the known diameter of the gauge bore. The resulting number will be the calibrated
diameter of the probe stylus tip.
STEP 4:
Test the result. press <F5-Probing>, Enter the calibrated probe diameter in the field
provided and press enter, then <F1-Bore>,and finally <Cycle Start>. The control will probe opposing
walls of the bore then stop in the center of the bore. The message box will appear on the screen and will
display the measured bore diameter /- 0.0002" if the calibrated tip diameter is correct and the
machine is in good condition. Adjust tip calibration diameter and repeat as needed.
STEP 5:
Go to the Tool Library and enter the calibrated diameter for the probe stylus in the tool#
you assigned to the probe in Parameter 12.
The Probe Stylus Calibration is now complete. Your DP-4 probe is ready for probing and digitizing!
