3.5.5 Example application involving TRAORI and frames

Example TOROT - Retraction from a slanted hole
When 5-axis transformation is active, TOROT generates a frame whose Z axis coincides with the
current tool orientation. This function can be used with a 5-axis program, for example, to retract
the tool after a tool breakage without collision, simply by returning the Z axis. Following tool
orientation with TOROT, all the geometry axis movements programmed will relate to the frame
generated as a result of this function.
Programming TOROT in MDI

TOROT to machining plane
TOROT for G17
TOROTY for G18 -> tool axis Y
TOROTX for G19 -> tool axis X
TOROT must be deselected prior to the next program start: TOROTOF.
A similar function is available in JOG with the manual retraction. After an interruption of a
tapping operation (G33/G331/G332) or a general drilling operation (tools 200 to 299) due to
power loss or a RESET at the machine control panel, you have the possibility to retract
the tool in the tool direction without damaging the tool or the workpiece.

; Activate TRAFO
; Calculate and select return frame
; Return movement by 50 mm in Z direction in a straight
line
; End of subprogram
A frame containing the current tool orientation
in the Z direction is generated
that in JOG mode, the tool can be returned
from the workpiece in the Z direction.
As an alternative to traversing incrementally in
MDI mode, in JOG mode you can use the
direction key to enable return in the tool
direction.
Notice:
Return is possible only in JOG mode if the
machine has been configured accordingly (Z
axis serves as the geometry axis).
