ADTECH9 Series CNC Programming Manual
To program a segment of arc, in addition to specifying end point and circle center position, it is also possible
by specifying radius and end point position. If the radius is specified with address R, the value of R can be
either positive or negative; a positive R value can be used to determine an arc smaller than 180°, and a
negative value can be used to determine an arc larger than 180°. Programming a full circle is only possible by
specifying circle center.
