[mfg-smartcam] N.P.T.

[Williams, Colin]

I am trying to cut: 1 1/4 - 11.5 npt on a Dainichi 18-t Fanuc control. Does anybody know what the G76 line should look like. What should the 'R' value in the second G76 line be? The problem I am having is that the taper on thread seems to be out, seems to cut bigger at the bottom end.

 

example:

 

G76 P10060 Q0020 R.0020
G76 X1.61 Z-0.68 P0000 R.0359 Q0110 F0.0869

 

Any help would be appreciated.

Thanks
