the circle starting point
Circle radius CR= and circle end position in Cartesian
coordinates X..., Y..., Z...
Opening angle AR= end point in Cartesian coordinates
X..., Y..., Z...
Opening angle AR= center point at addresses I...,

Circle through starting and end point and tangent
direction at starting point
Circular interpolation, CW
Circular interpolation counterclockwise
Circular interpolation through intermediate point
Circle with tangential transition defines the circle
End point in Cartesian coordinates
Circle center point in Cartesian coordinates in X, Y, Z direction
Circle radius
Opening angle
End point in polar coordinates, in this case the polar angle
End point in polar coordinates, in this case polar radius corresponding
to circle radius
Intermediate points in Cartesian coordinates in X, Y, Z direction
