Here, P = TW.
T = Torque
W = angular speed.
As speed increases, torque decreases and vice versa.
So, the cutting force will decrease as speed increases.
T = Torque
W = angular speed.
As speed increases, torque decreases and vice versa.
So, the cutting force will decrease as speed increases.

Cutting speed has no effect on cutting forces. But if cutting speed increases then power consumption and heat generation increases.

Since power required for cutting is FcV.
By conservation law, if V Increases Fc will decrease hence given option is correct.
By conservation law, if V Increases Fc will decrease hence given option is correct.

Since power input will always be constant, according to P=F.v
P= constant.
Therefore F is inversely proportional to v.
P= constant.
Therefore F is inversely proportional to v.

Increase in cutting speed causes cutting forces to remain unaffected or slightly reduced.

Increase in cutting speed provides better machinability and hence less cutting force.

Yes, I too agree with @Mahesh. Cutting forces are constant over the cutting velocity.
