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

•

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
