Finally, we'll set datum for the Z-axis:
• Position the tool so that its tip touches the top surface of your
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 your part); OR
Raise the quill to the desired 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 your datum set-
ting before you begin programming. To
confirm that your new datum is correct:
• Raise the tool and move the table
until both the X- and Y-axes dis
plays read "0.0000."
• Lower the tool until it touches your part.
• Check the tool's position—the lower left corner of the part should be
positioned directly beneath the center point of the tool.
• Now check the readout screen. If the Z-axis says "0.0000," then your
datum is accurate and you can begin programming. 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 go to
position is
0.0000 for both
X and Y, then
press the GO
key.
