Transformations
7.5 Orientations relative to the path
Job planning
7-38 Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
ORIPATH/ORIPATHS can be used to program various references to the path tangent via the
three angles
• LEAD= Specification of lead angle relative to the path and surface
• TILT= Specification of tilt angle relative to the path and surface
• THETA= Angle of rotation
for the entire trajectory. Polynomials up to the 5th degree can be programmed in addition to
the THETA angle of rotation using PO[THT]=(...).
Note
Machine manufacturer
Please refer to the machine manufacturer's instructions. Other settings can be made for
orientations relative to the path via configurable machine and setting data. For more detailed
information, please refer to

Parameters
Various settings can be made for the interpolation of angles LEAD and TILT via machine
data:
• The tool-orientation reference programmed using LEAD and TILT is retained for the
entire block.
• Lead angle LEAD: rotation about the direction vertical to the tangent and normal vector
TILT: rotation of the orientation about the normal vector.
• Lead angle LEAD: rotation about the direction vertical to the tangent and normal vector
Tilt angle TILT: rotation of the orientation in the direction of the path tangent.
• Angle of rotation THETA: rotation of the tool about itself with an additional third rotary axis
acting as an orientation axis in 6-axis transformation.
Note
Orientation relative to the path not permitted in conjunction with OSC, OSS, OSSE, OSD
and OST
Orientation interpolation relative to the path, that is ORIPATH or ORIPATHS and ORIOTC,
cannot be programmed in conjunction with orientation characteristic smoothing with a
G code from group 34. OSOF has to be active for this.
