I am trying to cut 1"-24 ID threads that are 1.250 deep. I keep chiping the tip of the insert on the curly chip build up in the tube. I need some input from some of you about what to try. I feel like the last couple of passes need to be even finer than they are now. Here is the code I am using:
t404;
G54;
G97 S500 M03;
G00 X0.906 ;
Z0.125 ;
G04 P1. ;
M23 ;
G76 X1. Z-1.25 K0.042 I0. D0.0001 f0.0417 ;
G00 X0.906 Z10. ;
M30 ;
;
Can you tell me what the K,I,X, are in the G76?
can you make a suggestion of something to try?
Oh the material is 4130 seamless tubing.
Thanks
Leroy
