1) The axes are always rotated in the same sequence for calculating the
tilt of the plane: The TNC first rotates the A axis, then the B axis, and
finally the C axis.
Cycle 19 becomes effective as soon as it is defined in the program. As
soon as you move an axis in the tilted system, the compensation for
this specific axis is activated. You must move all axes to activate
compensation for all axes.
If you set the function Tilting program run to Active in the Manual
Operation mode, the angular value entered in this menu is overwritten
by Cycle 19 WORKING PLANE.
Please note while programming:
The functions for tilting the working plane are interfaced to
the TNC and the machine tool by the machine tool builder.
With some swivel heads and tilting tables, the machine
tool builder determines whether the entered angles are
interpreted as coordinates of the rotary axes or as
mathematical angles of a tilted plane. Refer to your
machine tool manual.
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.
The working plane is always tilted around the active
datum.
If you use Cycle 19 when M120 is active, the TNC
automatically rescinds the radius compensation, which
also rescinds the M120 function.
Danger of collision!
Ensure that the last defined angle is smaller than 360°.
