In turning, V= pi*D*N/60 for maintaining constant velocity as dia decreases, spindle speed (N ) should be increased.

Rahul said:   7 years ago
Acc to v= πdn/60,
Here v is directly proportional to dia, so if dia decrease cutting speed is also decreased.

Nadim said:   10 years ago
As diameter decrease velocity of cutting decrease to maintain same velocity spindle speed should be increased.

Cutting speed decreases. But to compensate that we have to increase the spindle RPM.

How can spindle speed changes?
