A turning operation has a spindle speed of 900rpm. The tool has a feed of 35mm/min. You have to reduce a bar stock diameter from 65mm to 59mm. What is the speed of the spindle in rad/s ? What is the linear speed of the workpiece? What is the material removal rate in both mm^3/min and in^3/min? If you are machining an alloy steel (5140 H), what is the power requirement in kW?
