Answer questions (c) and (d)

Calculate the Material Removal Rate of a round bar with diameter 26 mm, is being reduced in diameter to 22 mm by a Turning Process. The feed is 0.24 mm/rev, spindle rotation speed is 22 rev/min? (TWO decimals) (Please note the values may change between each attempt!)

In plane-strain orthogonal machining, the two main sources of energy dissipation are deformation along the shear plane (~70%) and friction at the tool-chip contact along the rake face (~30%). Consider plane-strain machining of a rigid perfectly-plastic work material whose uniaxial yield stress is 700 MPa, and is independent of strain rate and temperature. A tool of zero-degree rake angle is employed. Measurements showed the (deformed) chip thickness to be twice that of the undeformed chip thickness. Based on the aforementioned distribution of energy, estimate the specific energy for this process.

A student is performing a turning operation with a workpiece with an initial diameter of 40 mm to produce a 30 mm diameter rod that is 100 mm long. The lathe power is 20 kW and is operating on 85% mechanical efficiency. If the student set the cutting speed to 0.5 m/min and the cutting tool is set to have a rake angle of 5 degrees:  a.) What material can we choose for the rod is the coefficient of friction is 0.5? b.) If we select 4130 normalized heat-treated steel for the rod, and coefficient of friction is 0.5, what will the maximum depth of cut we can achieve?

(b) A 400 mm long, 19.5 mm diameter of 304 stainless steel rod (assume specific energy of steel is 4 W.s/mm³) is being reduced in diameter to 17 mm by turning on a lathe machine. The spindle rotates at N = 700 rpm, and the tool is traveling at an axial speed of 300 mm/min.
