According to the Merchant Equation, an increase inrake angle would have which of the following results, if allremaining factors are constant (more than one correct answer): a.Decrease in friction angle b. Decrease in power requirements c.Decrease in shear plane angle d. Increase in cutting temperature e.Increase in shear plane angle 3. State and describe the orthogonalcutting model. Define chip ratio and explain why chip ratio isalways < 1.0. 4. Explain the effect of cutting temperature inmachining on the chip formation and finish of the machined parts.5. Describe and state the difference between roughing and finishingin machining operations. 6. Define (a) cutting power, (b) GrossPower, and (c) Specific Power along with pertinent equations. 7.State and briefly describe the 3 stages of Tool Wear Rate using aplot. 8.
