DRO
MILLPWR ®
Operation Manual 2-11
Setting datum for the Z-axis:
• Position the tool so that its tip touches the top surface
of the part.
• Using the keypad, enter "0" into the "Z" field
(or press the Z = 0 softkey).
• Press the ENTER key.
• Highlight the “Z Retract” field.
• Either:
Enter the Z-axis retract position (the position that you want the quill to return to
between steps—it must be located above the top surface of the part); OR
Raise the quill to the desired retract position, then press the TEACH softkey.
• Press the USE key.
Datum and the Z-axis retract position have now been established.
It's a good idea to test the datum setting
before beginning programming. To confirm
that the new datum is correct:
• Raise the tool and move the table until
both the X- and Y-axes displays read
"0.0000."
• Lower the tool until it touches the part.
• Check the tool's position. The lower left
corner of the part should be located
directly beneath the center point of the tool.
• Now check the readout. If the Z-axis display says "0.0000," then the
datum is accurate and programming can begin. If a value other than
0.0000 appears in the Z-axis display, repeat the procedure for establishing
datum.
You can quickly
move to Datum
for X and Y by
pressing the
POS key. Check
that your posi-
tion is 0.0000
ABS for both X
and Y, then
press the GO
key.
