Circular-to-Circular Blocks
When the coordinates of the point of intersection of a circular path into a
circular path are not known, use the following format. A G13 or G13.1
must be programmed. If using this format the R--word cannot be
used to
specify the radius of an arc in either of the circular blocks. These blocks
must be programmed in absolute.
Format:
G13G02K__I__;
G02 Z__X__K__I__;
Important: The I and K integrands in the s econd circular block of this
QPP format are not the same values as used for normal circular
interpolation. In this case, they specify the distance from the end point
of
the second arc to the center of that arc. At least one of these integrand
words must be programmed in each of the two circular blocks.
Neither circular block can contain an angle word (A) when using this
format.
