8 Tilt axis and tilt angle?: Enter the axes of rotation
together with the associated tilt angles. The rotary
axes A, B and C are programmed using soft keys.
If the TNC automatically positions the rotary axes, you can enter the
following parameters:
8 Feed rate ? F=: Traverse speed of the rotary axis
during automatic positioning.
8 Set-up clearance? (incremental value): The TNC
positions the tilting head so that the position that
results from the extension of the tool by the set-up
clearance does not change relative to the workpiece.
Cancellation
To cancel the tilt angle, redefine the WORKING PLANE cycle and enter
an angular value of 0° for all axes of rotation. You must then program
the WORKING PLANE cycle once again by answering the dialog
question with the NO ENT key to disable the function.
Because nonprogrammed rotary axis values are
interpreted as unchanged, you should always define all
three spatial angles, even if one or more angles are at zero.
