13) Move the machine tool to bring the
display value on X- and Y-axes
into zero, reach the start point of R.
14) Key or and the position of any processing point may come to be
displayed, and you can move the machine tool to bring the display values on
the both axes into zero and reach the position of the corresponding point of the
R circular arc.
Note: When the arc to be processed in Planes XZ and YZ covers the 90°
or the 270° position, for example, the one from 210° to 330° covers 270°
in Fig.(c), and the other from 135° to 45° covers 90° in Fig. (d),end mill
shall not be used.

) *Take the processing of the working piece shown in the figure on the
right as the third example:
1. For the processing of this working piece, it is
necessary to calculate out the start and end angles
of the arc at first.
Refer to the figure.

=arc cos(17.3/2)/10
≈
30°
The start angle (ST ANG)of the arc is 30°,
and the end angle (ED ANG) is 150°.
