The radius may also be programmed in a block prior to the one defining
the circular interpolation. In this case, the radius is defined using the
assignments "R1=<radius>" or "G263=<radius>".
The CNC keeps the radius value until a circular interpolation is
programmed by defining the center coordinates or a movement is
programmed in polar coordinates.
Different formats to define the same arc.

The previous examples make semicircles of a 50 mm radius. Although the
examples use function "G263=<radius>", they're also valid if they are
programmed using "R1=<radius>".

When programming an arc using the radius, it is not possible to
program full circles because there are infinite solutions.
