Example 2: ORID
If ORID is active, then all blocks between the two traversing blocks are executed at the end
of the first traversing block. The circle block with constant orientation is executed
immediately before the second traversing block.
Program code
ORID
N8 A2=... B2=... C2=...
N10 X... Y... Z...
N12 A2=... B2=... C2=...
N14 M20
N20 X... Y... Z...
Note
The method which is used to change orientation at an outer contour is determined using the
program command that is active in the first traversing block of an outer corner.
Without change in orientation:If the orientation is not changed at the block boundary, the
cross-section of the tool is a circle, which touches both of the contours.

Comments
; The N12 and N14 blocks are executed at the end of N10.
The circle block is then executed with the actual
orientation.
