Explanation of the commands
ORIMCS
Rotation in the machine coordinate system
ORIWCS
Rotation in the workpiece coordinate system
Function
When programming orientation in the workpiece
coordinate system with Euler or RPY angles or
orientation vector, the turning movement can be set
via ORIMCS/ORIWCS.
Sequence
With ORIMCS, the tool movement depends on the
machine kinematics. On a change in orientation where
the tool tip is fixed in space, linear interpolation is
performed between the rotary axis positions.
With ORIWCS, the tool movement is performed
independently of the machine kinematics. On a
change in orientation where the tool tip is fixed in
space, the tool moves in the plane created from the
starting and end vectors.
