Problem- Torque Control on B-axis

[JHECNC]

I have a Daewoo Puma 200SY with Fanuc 18i-TB control and am trying to utilise the torque control on the B-axis for turning long parts.I have posted a question about this on the Daewoo/Doosan Forum but as yet have had no replies (lots of views though).
I have tried programming a "G300 B-200" as stated in the programming manual available on this site but the m/c bombed out and I got an error message...."Part off failed".
after a bit more digging I tried the program below but had to reposition the centre again before the finish pass due to vibration

Tool Call G54 etc.
G98
G00 B-257
M86
G31 P99 B-280 F100
M87
G99
G96 S200 M203
"Rough"
"Finish"

ended up as :

Tool Call G54 etc.
G98
G00 B-257
M86
G31 P99 B-280 F100
M87
G99
G96 S200 M203
"Rough (G71)"
"End tool"

"Call up finish tool"
Tool Call G54 etc.
G98
G00 B-257
M86
G31 P99 B-280 F100
M87
G99
G96 S200 M203
"Finish pass (G70)"

End Program

Can any one help with the correct format of G-Code for this op ?
Thanks

Are you still having trouble with this? I you this same function on one of our Takisawa mill/turns with 18i. The code looks the same. Let me know I'll give you what I use.
