12.9 Tilting the W
o
rk
ing Plane (Sof
tw
ar
e Option 1)
Traversing the 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 "Activating manual tilting", page 360.
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 probing function for basic rotation is not available if you have
activated the working plane function in the Manual Operation mode.
„ 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.
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.
