2 Manual Operation and Setup
2.4 Tilting the Working Plane (not on TNC 407)
Traversing the reference marks in tilted axes
With tilted axes, you use the machine axis direction buttons to cross
over the reference marks. The TNC interpolates the corresponding axes.
Be sure that the function for tilting the working plane is active in the
manual operating mode and the actual angle of the angular axis was
entered in the menu field (see page 2-11).
Setting the datum in a tilted coordinate system
After you have positioned the tilted axes, set the datum in the same way
as for non-tilted axes—either manually by touching the workpiece with the
tool (see page 2-7) or, much more easily, by allowing the part program to
automatically set the datum with the aid of the HEIDENHAIN 3D touch
probe system (see page 9-11).
The TNC then converts the datum for the tilted coordinate system. The
angular values for this calculation are taken from the menu for manual
tilting, regardless of whether the tilting function is active or not.
The angle values entered in the menu for manual tilting (see page 2-11) must match the actual position of the angular
axes. Otherwise the TNC will calculate an incorrect datum.
Position display in the tilted system
The positions displayed in the status window (NOML and ACTL) are in the
tilted coordinate system.
Limitations on working with the tilting function
• The touch probe function BASIC ROTATION cannot be used.
• PLC positioning (determined by the machine tool builder) is not
possible.
