Path-related interpolation
Tool orientation in relation to the path.
This is used with the commands LEAD and TILT and the
specification of the surface normals with A4, B4, C4 and A5, B5,
C5.
The orientation vector is set relative to the
path and to the surface normals. The
programming is performed using the LEAD
angle and the TILT angle in conjunction with
the surface normal vector. LEAD describes a
rotation around the direction perpendicular to
the tangents and normals while TILT
describes a rotation of the orientation around
the surface normal vector.
The orientation interpolation with ORIPATH is
recommended when programming on the
CAM system during the machining of free-
form surfaces in tool and mold-making. The
prerequisite for this is support of the issuing of
surface normals of your CAM system.
