Conclusions

we used different cutting velocities.

when the cutting velocity is more the material removal was also more,with increased velocity material removal rate increased.

with higher cutting velocity total deformation of workpiece was also increased.

equivalent stress is decreased with increase in the cutting velocity.

with increase in the cutting velocity temparature developed on workpiece also increased.
