Please note while programming:
Cycle parameters
U 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:
U Feed rate? F= : Traverse speed of the rotary axis
during automatic positioning. Input range: 0 to
99999.999
U 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
Resetting
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 and respond to the dialog
question with the NO ENT key to disable the function.
The functions for tilting the working plane are interfaced to
the TNC and the machine tool by the machine tool builder.
For certain swivel heads and tilting tables the machine tool
builder specifies whether the entered angles are
interpreted as coordinates of the rotary axes or as
mathematical angles 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.
