Traversing reference points in tilted axes
The TNC automatically activates the tilted working plane if this
function was enabled when the control was switched off. Then
the TNC moves the axes in the tilted coordinate system when
an axis-direction key is pressed. Position the tool in such a way
that a collision is excluded during the subsequent crossing of
the reference points. To cross the reference points you have to
deactivate the "Tilt Working Plane" function , see "To activate
manual tilting:", page 526.
Danger of collision!
Be sure that the function for tilting the working plane
is active in the Manual Operation mode and that the
angle values entered in the menu match the actual
angles of the tilted axis.
Deactivate the "Tilt Working Plane" function before
you cross the reference points. Take care that there
is no collision. Retract the tool from the current
position first, if necessary.
Position display in a tilted system
The positions displayed in the status window (ACTL. and NOML.)
are referenced to the tilted coordinate system.
Limitations on working with the tilting function
The actual-position-capture function is not allowed if the tilted
working plane function is active.
PLC positioning (determined by the machine tool builder) is not
possible.
