Functionality
The "Thread recutting" function is a subfunction of "Manual thread cutting". It can be used to
recut a thread or to continue machining the thread on a workpiece that has been unclamped
in between.
To make "Thread recutting" to proceed correctly, you have to enter the appropriate values in
the "Thread Cutting" screen form.
Operating sequences
Note
The "Thread recutting" function uses the entry values from the "Thread Cutting" screen form.
This screen form must therefore have been completed so that thread cutting can proceed
correctly.
You can call the thread recutting function with softkey "Thread repair".
The following screen form appears:
Figure 3-39
The values displayed for start of thread, end of thread and axis position relate to the type of
thread selected.
Longitudinal and taper thread ≤ 45° (Z axis)
Face and taper thread ≤ 45° (X axis)
All values displayed on this screen form are for information only; it is not, therefore, possible
to alter them directly.
