Circular interpolation (G02, G03)
The programming order of the axes is always maintained regardless of the plane selected,, as are
the respective center coordinates.
Polar coordinates
It is necessary to define the angle to be traveled Q and the distance from the starting point to the
center (optional), according to the axes of the work plane.
The center coordinates are defined by the letters I, J, or K, each one of these being associated to
the axes as follows:
If the center of the arc is not defined, the CNC will assume that it coincides with the current polar
origin.
Programming format:
Cartesian coordinates with radius programming
The coordinates of the endpoint of the arc and radius R are defined.
Programming format:
If a complete circle is programmed, with radius programming, the CNC will show the corresponding
error, as infinite solutions exist.
If an arc is less than 180o, the radius is programmed with a plus sign, and a minus sign if it is more
than 180o.
