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 angular
components of a tilted plane.
Refer to your machine 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.
Cycle parameters
Rotary 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. Input range -360.000 to 360.000
If the TNC automatically positions the rotary axes, you can enter
the following parameters:
Feed rate? F=: Traverse speed of the rotary axis
during automatic positioning. Input range: 0 to
99999.999
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. Input range: 0 to 99999.9999
