19.9.5 Execution example. Selecting a solution.
The example assumes a CB spindle type kinematics. The starting program will be a circle
in the XZ plane.

If the part rotates 90º with respect to the C axis, the result will be a circle in the YZ plane.
In block N2 there is a path discontinuity greater than 5º between what has been programmed
and what has been calculated which is the default value for the angle that may be
programmed in the instruction DEFROT. Depending on the criterion chosen, one may select
solution 1 or 2 and from there on keep positioning in the rest of the blocks.
• With #DEFROT [DPOSF] (positive direction of the main axis), solution 1 is chosen and
the resulting positioning of the rotary axes will be the following.
N2 C90 B10
N3 C90 B20
N4 C90 B30
• With #DEFROT [DNEF] (negative direction of the main axis), solution 2 is chosen and
the resulting positioning of the rotary axes will be the following.
N2 C-90 B-10
N3 C-90 B-20
N4 C-90 B-30
If WARNING (issue a warning and generate a stop) is chosen when defining the criterion
in #DEFROT, the CNC will select the solution according to the chosen criterion. The CNC
will also display an interactive screen offering the option to change from one solution to
another in that motion block, both in its starting orientation and in the final one.
