Css okuma lathe
Hi! I need help with constant surface speed.
I saw a video at youtube and the guy learned me to set 3 codes.
For example
Code
G97 s1500 m03
G50 s2000
G96 s600
G50 s2000
G96 s600
I want the lathe to start at 1500rpm and as closer it gets to the center the closer the rpm will be to 2000rpm but now it's the opposite... what am i doing wrong

I used this sequence:
G96 S600 M3 (Set CSS Spindle speed in SFM)
Because you are turning on G96(CSS-Contant Surface Speed) your first G97 line is irrelevant.
Also because you are not applying m3 (if i remember how this works) your third line never works.
Because you are working with CSS your actual RPM at any point will depend on the commanded X value.
Perhaps your X is something weird?
Try the code i supplied. It should work
