I recently had a call for advice from a shop that bought a 6T Mori and needed help.
I sent him this example from my website, older machines are still around and sold a lot, maybe it can help somebody else.
The 2 line version came in with the Fanuc 0T, the 6T had the 1 line version, but is quite similar.
------------------------
Here is an example of the G76 as it should be, its part of my DVD called Cycles.
The only difference is that this is the 2 line version, you have 1 line.
Its for the 0T control and did not need the G50 dimensions.
You can not use G96, use G97.
Example: G76 Threading Cycle in 2 line format for OT and later controls.
2" diameter, 20 Threads per Inch, Mild Steel.
O2006*
N1 G50 S1500*
N2 T0101*
N3 G97 S700 M3*(Speed for threading, always in RPM)
N4 G0 X2.2 Z.2 M8*(Rapid to above part, .2" from face)
N5 G76 P021060 Q20 R5*(The first 2 digits in P represent the amount of finish
passes, the next 2 are the pullout distance at the end of the threading motion,
expressed in tenths of revolutions, the 60 is the angle of the tool)
N6 G76 X1.94 Z-1.0 P300(total thread depth) Q150(depth of first cut) F.05*
R if needed is the amount of taper over total distance in thread motion.
The P value is figured by taking the F-value times the constant of .6, once
figured you also have the X value.
N7 G0 X6.0 Z6.0 M9*
N8 M30*
If any of you need help, advice is free.
