Arc
An arc can be defined several ways:
•
With a From point, To point and a radius
•
With a From point, To point and a center point
•
With a From, To and a 3rd point along the arc
•
With a From or To point, center point and a
sweep angle
Choose a method based upon the information available from your print. While programming,
keep in mind that the arc's sweep angle is measured from the X-axis.
To program an arc:
•
Press the
ARC
key.
•
Enter the beginning coordinates for the X-axis (X1) and Y-
axis (Y1) in the “From” field.
•
Enter the ending coordinates for the X-axis (X2) and Y-axis
(Y2) in the “To” field.
•
Enter the begin and end depths for the Z-axis.
•
Enter the Z-axis feed rate.
•
Enter the arc's radius, then press either the
MAJOR ARC
or
MINOR ARC
softkey. (A major arc has a sweep angle greater
than 180 degrees; a minor arc’s sweep angle is less than 180
degrees.)
