The TNC is now ready for operation in the Manual Operation mode.
Crossing the reference point in a tilted working plane
The reference point of a tilted coordinate system can be crossed by
pressing the machine axis direction buttons. The “tilting the working
plane” function must be active in the Manual Operation mode (see
“Activating manual tilting,” page 95). The TNC then interpolates the
corresponding axes.
If available, you can also traverse the axes in the direction of the
current tool axis (see “Setting the current tool-axis direction as the
active machining direction (FCL 2 function)” on page 96).
If one of the two functions that were active before is active now, the
NC START button has no function. The TNC outputs a corresponding
error message.
The reference points need only be crossed if the machine
axes are to be moved. If you intend only to write, edit or
test programs, you can select the Programming and
Editing or Test Run modes of operation immediately after
switching on the control voltage.
You can cross the reference points later by pressing the
PASS OVER REFERENCE soft key in the Manual
Operation mode.
Make sure that the angle values entered in the menu for
tilting the working plane match the actual angles of the
tilted axis.
If you use this function, then for non-absolute encoders
you must confirm the positions of the rotary axes, which
the TNC displays in a pop-up window. The position
displayed is the last active position of the rotary axes
before switch-off.
