Running a Program
There are a few things that may need to be done before running a program, such as skewing
the part and establishing datum.
Skewing a Part
Note: It is important to skew a part prior to establishing datum for accuracy.
Save time setting up a job by skewing the part. The skew function automatically compen-
sates for the angle offset of the part. If a part is not perfectly parallel with either the X- or
Y-axis, indicating it in is not necessary.
To skew a part, simply “touch off” on two or more points along one axis (either X or Y).
Use an electronic edge finder to skew the part, or use a mechanical indicator and teach
position—either way, it’s fast and easy.
Note: Choose a line to make parallel with the table’s X- or Y-axis—do not enter coor-
dinates along a curve, along two different lines, or along a line that is positioned
at a 45 degree angle.
MILLPWR will calculate the skew angle based upon a
straight line between the points entered.
If you are working with a part that has a rough edge, it’s best to enter multiple points
along the straightest edge so that
MILLPWR can more accurately compensate for the skew
angle.
Note: When two or more points are entered in the skew calculator MILLPWR will calcu-
late the angle and adjust the X and Y plane. Angles that are less than 45° are
adjusted down to the X-axis, and angles greater than 45° adjust up to the Y-axis.
Note: The skew feature does not not work with G-code programs. Remove any skew
angle prior to running a G-code program.
