22.31 Do you think that there is a relationship between the cost of a cutting tool and its hot hardness? Explain.
(USCS units) A turning operation is performed using a rake angle of 15°. Cutting speed = 200 ft/min, feed= 0.012 in/rev, and depth of cut = 0.100 in. The chip thickness ratio measured after the cut = 0.48. Determine (a) chip thickness after the cut, (b) shear angle, (c) friction angle, (d) coefficient of friction, and (e) shear strain (USCS units) The turning operation in the previous problem involves a work material whose shear strength = 52,000 lb/in2. Based on your answers to the previous problem, compute (a) shear force, (b) cutting force, (c) thrust force, and (d) friction force.

What are the three main deformation zones in metal cutting and how does the heat distributeover a metal during any cutting process
A student is using a lathe with 80-hp and 80% efficiency to fabricate a copper alloy with Sy = 1200ksi If the width of cut is 0.30 inand the student set a rake angle of 0and a cutting speed of 200fl / min while she assumed a coefficient of friction to be 0.5. What is the maximum depth of cut the student can achieve?
a) Define specific energy for plane strain machining (cutting). b) 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.
