Detailed description
2.1 Circumferential milling
Special case
Intermediate blocks without traversing and orientation motions are executed at the
programmed positions, e.g. auxiliary functions.
Example:
N70 X60
N75 M20
N80 A3=1 B3=0 C3=1
N90 Y60
Blocks N75 and N80 are executed after N70. The circle block is then executed with the
current orientation.
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.
