8.6 Tool orientation
Tool orientation is the term given to the geometrical
alignment of the tool in space.
On a 5-axis machine tool, the tool orientation can be
controlled with program commands.
Programming tool orientation
A change in tool orientation can be programmed by:
• Direct programming of the rotary axes
• Euler or RPY angle
• Direction vector
• LEAD/TILT (face milling)
The reference coordinate system is either the
machine coordinate system (ORIMCS) or the current
workpiece coordinate system (ORIWCS).
A change in orientation can be controlled by the
following:
ORIC
ORID
OSOF
OSC
OSS
OSSE
ORIS
