Tilting The Working Plane Through Axis Angle: Plane Axial - HEIDENHAIN TNC 640 User Manual

Tilting the working plane through axis angle:
PLANE AXIAL
Application
The PLANE AXIAL function defines both the slope and the
orientation of the working plane and the nominal coordinates of the
rotary axes.
PLANE AXIAL can also be used on machines that have
only one rotary axis.
The input of nominal coordinates (axis angle input) is
advantageous in that it provides an unambiguously
defined tilting situation based on defined axis positions.
Spatial angles entered without an additional definition
are often mathematically ambiguous. Without the use
of a CAM system, entering axis angles, in most cases,
only makes sense if the rotary axes are positioned
perpendicularly.
Refer to your machine manual.
If your machine allows spatial angle definitions, you can
continue your programming with PLANE RELATIV after
PLANE AXIAL.
Programming notes:
The axis angles must correspond to the axes present
on the machine. If you try to program axis angles
for rotary axes that do not exist on the machine, the
control will generate an error message.
Use PLANE RESET to reset the PLANE AXIAL
function. Entering 0 only resets the axis angle, but
does not deactivate the tilting function.
The axis angles of the PLANE AXIAL function are
modally effective. If you program an incremental
axis angle, the control will add this value to the
currently effective axis angle. If you program two
different rotary axes in two successive PLANE AXIAL
functions, the new working plane is derived from the
two defined axis angles.
The SEQ, TABLE ROT and COORD ROT functions
have no effect in conjunction with PLANE AXIAL.
The PLANE AXIAL function does not take basic
rotation into account.
