Circular-to-Linear Blocks
When the coordinates of the intersection of a circular path into a linear
path are not known, use the following format. A G13 or G13.1 must be
programmed in the first of the two blocks and absolute coordinate values
must be used.
Format:
G13G02I__K_;
or
G13G02R__;
G01A__Z__X__;
G01A__Z__X__;
Important: K values are the normal integrand values when using this
format (measured from start point of arc to arc center). These are
described on page 12-5.

Important: R cannot be programmed to specify the arc radius for
linear-to-circular block combinations unless the two paths are tangent.
