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.

o 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.)
