Unless a point of intersection is found in a
linear-to-linear transition, the path of the tool
will be:
Unless a point of intersection is found in a
linear-to-circular transition, the path of the tool
will be:
Unless a point of intersection is obtained in a
circular-to-linear or circular-to-circular
transition, the end of compensation vector in the
start point of the first circular interpolation will
be connected with the end point of the
compensation vector perpendicular to the start
point of the second interpolation by a circular
arc of uncorrected programmed radius R. Now
the center of the interconnecting circular arc will
not coincide with the center of the programmed
arc. The control will return error message 3047
CHANGE NOT POSSIBLE if the direction
change is not feasible even with the relocation of
the circle center outlined above.
