Steps to Establish the datum
Where and how you establish the datum will vary from job to job. The
following step, by step process is a common method of establishing a
datum. Being familiar with the basics, the same principles will apply
for other parts, making adjustments to the procedure as needed when
setting the datum.
 From the DRO mode, press the Datum soft key.
 In the datum number field, enter a number for the datum to be
defined. Since this will be the first datum being defined, use the
number 1.
 Insert a tool into the spindle (e.g. such as the tool for the first cut).
This example will establish the datum on the corner where the left,
front and top surfaces of the part intersect. This will be accomplished
by “touching” each face with the tool that will make the first cut to the
part.
 In the SET DATUM dialogue the X, Y and Z fields are always active,
displaying the machine position relative to the selected datum.
 Open the SET DATUM dialogue to view the machines position
relative to any defined datum number by entering the number in the
DATUM NUMBER field. Then press ENTER, or ARROW DOWN. This
provides the operator with a constant quick reference for the datum
selected.
 Viewing other datum numbers does not change the selected datum
displayed in the Status Bar. To change to another defined datum,
press the USE key.
 When a new datum number is defined, or another number is
selected, and the USE key is not pressed, all information entered is
discarded, and the current active datum number is retained.
When Tool information is listed in the Status Bar at the top
of the screen, it is ignored by the MILLPWR
G2
when
establishing a datum. The information for the tool that is
actually being used to establish the datum must be used.
Using the calculator in an entry field in a dialogue requires
the operator to press the ENTER key to perform the
calculation. To move to the next field using the ENTER key
requires the operator to press ENTER a second time.
