I have recently started to learn how to program/run the TL-2 at work. I ran a face,turn,chamfer program and added a threading G76 cycle. as below

The thread is or looks perfect on a pitch gauge and the od of the shaft prior to threading is 15.99mm OD. The thread i'm trying to cut is an M16x2. It appears to be very close but once threaded the O/D measures 16.2/16.3. Is there a way of programming in several spring cuts?
The manual I have dosen't really show much detail. I would be grateful for any help.
Many Thanks.
 
I usually out put the program and the copy and paste the program below the previous program and change the depth of cut to 0.03 .
