Which assumption(s) made by Merchant's model and Lee and Shaffer prediction on shear angle are similar? [a] Coefficient of friction is dependent on workpiece and tool material combination. [b] The shear angle is affected by the associated angles between cutting force and force acting parallel to the rake face. [c] Shear plane will orientate itself such that minimum force are acting on the plane. [d] The shear angle is affected by the angles between the cutting and resultant force. [e] None of the above. Lee and Shaffer shear angle model will be impracticable in which situation(s)? [a] The feed force is substantially larger than the cutting force. [b] The cutting force is substantially larger than the feed force. [c] Negative rake angle with forces parallel to rake face substantially higher than perpendicular to rake face. [d] Zero rake angle with forces parallel to rake face substantially lower than perpendicular to rake face. [e] None of the above. In which thermal softening index condition(s) will Lee and Shaffer model be accurate? [a] Thermal softening index is equal to 1 [b] Thermal softening index is greater than 1 by less than 1.5 [c] Thermal softening index is less than 1 [d] Thermal softening index is substantially greater than 1. [e] None of the above. Which assumption(s) made by Merchant's model and Lee and Shaffer prediction on shear angle are similar?
