The ORIC and ORID program commands are used to determine whether changes in
orientation programmed between two blocks are executed before the inserted circle block is
processed or at the same time.
When the orientation needs to be changed at outside corners, the change can be
implemented in parallel to interpolation or separately from the path motion. When ORID is
programmed, the inserted blocks are executed first without a path motion (blocks with
changes in orientation, auxiliary function outputs, etc.). The circle block is inserted
immediately in front of the second of the two traversing blocks which form the corner.
ORIC
If ORIC is active and there are two or more blocks with changes in orientation (e.g. A2= B2=
C2=) programmed between the traversing blocks, then the inserted circle block is distributed
among these intermediate blocks according to the absolute changes in angle.
Change in orientation
The method by which the orientation is changed at an outer corner is determined by the
program command that is active in the first traversing block of an outer corner.
