Detailed description
(1) Automatic calculation of two-arc contact
When two continuous circular arcs contact with each other and it is difficult to find the contact,
the contact is automatically calculated by specifying the center coordinates position or radius
of the first circular arc and the end point (absolute position) and center position or radius of the
second circular arc.

I and K
:
Incremental position from arc end point
P and Q
:
Arc center position (absolute position)
I and K are the arc center position (incremental position); distances from the start point in the
first block or distances from the end point in the second block. P and Q (X, Z arc center
position (absolute position)) can be commanded instead of I and K commands.
