Hyundai Kia SKT 250 Fanuc OI-TC ---RPM Problems

[mkoomen]

If you program spindle speed of 100, it will run at spindle speed of 188. It seems to run 88 percent faster than programmed. Is there a parameter that needs to be set?

[CNCRim]

Is this lathe or mill? If lathe it's normal because bigger diameter take more time to travel, so when the tool travel to the center the spindle suppose to rev to infinity. since that had been said nothing wrong when the spindle faster than program number.

If you run it in G96 than it will be changing RPM with diameter, if you setup G97 you will have constant RPM no matter what diameter you cutting.
