The Taylor tool-life equation is directly applicable to flank wear. Explain whether or not it can be used to model tool life if other forms of wear are dominant.

In an orthogonal cutting test, the cutting force and thrust force were observed to be 1000N and 500 N respectively. If the rake angle of tool is zero, What is the coefficient of friction in chip-tool interface ?

2 2.46 Describe in detail your thoughts regarding the technical and economic factors involved in tool-material selection.

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.

(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.
