(3) Example of operation
(Example)
When using a 4-axis system with the X axis as the 1st axis and, Y, Z, C in the order,
set the parameters (ret1 and ret2) as shown below.
ret1 00001011
ret2 00001100
In this case, the return movement path will be as shown below.
#1
#2
#1
#2
1) X axis, Y axis
5) X axis, Y axis, C axis
3) All axes
4) Z axis
2) Z axis, C axis
Return path
Retract path
1st transit point
2nd transit point
Interruption point
Return start point
(4) Others and precautions
(a) If reset is applied between the designation of the interruption point and the restart of
machining (in other words, during the retract mode), the memorized transit points and
interruption point will be canceled. The halted or stopped automatic operation will be reset and
finished.
(b) The tool compensation amount cannot be changed during the retract mode.
(c) The manual random feed function cannot be used during the retract mode.
(d) As for the override, the manual override is valid.
(e) The single block is valid.
(f) If reference point return is carried out during the tool retract return, the tool compensation
amount will be invalidated when the reference point return is completed. Thus, if the tool is
compensated before tool retract , when the tool is returned after reference point return, the
path will shift by the tool compensation amount at the block following the block containing the
interruption point.
Thus, if the operation mode is changed to reference point return during tool retract return, a
warning will occur.
Warning occurrence
conditions
•
If the reference point return mode is selected during the tool
retract return mode, "OPW168 Ref.pnt ret cancel tool offset"
will occur.
Warning reset conditions
•
When the operation mode is changed to a mode other than
reference point return before the axis returns to the
reference point.
•
When the tool return is completed.
•
When reset 1 is input.
•
When emergency stop occurs.
(Note)
As this warning is only on display, reference point return can be carried out correctly.
1) X axis and Y axis move simultaneously.
2) Z axis and C axis move simultaneously.
3) All axes move simultaneously.
4) Z axis moves.
5) X axis, Y axis and C axis move
simultaneously.
