What am I doing wrong I am turning the following thread internally:
5 TPI
6 Start
I have the following code:
G00 T909
M24
G97 S100 M03
G00 G54 X3.06 Z0.2
G76 X3.5251 Z-0.5 K0.1365 D0.04 F1.2
G00 X3.06 Z0.4
G76 X3.5251 Z-0.5 K0.1365 D0.04 F1.2
G00 X3.06 Z0.6
G76 X3.5251 Z-0.5 K0.1365 D0.04 F1.2
G00 X3.06 Z0.8
G76 X3.5251 Z-0.5 K0.1365 D0.04 F1.2
G00 X3.06 Z1.
G76 X3.5251 Z-0.5 K0.1365 D0.04 F1.2
G00 X3.06 Z1.2
G76 X3.5251 Z-0.5 K0.1365 D0.04 F1.2
G00 X3.06
From research I thought feedrate = # of starts/TPI
Z stepover = pitch
But when I try to screw in (Plastic bottle) into these female threads it "DON'T SCREW!!"
I have even tried threading with just one start with feedrate of F0.2 and they thing screws in perfectly.
I have tried slower RPMs thinking that 120ipm is too fast but this does nothing.
Any help sure would be appreciated.
