Question 3 (a) Explain why steam (moisture) conditioning is required in nylon fiber production. (4 marks) (b) Using the Taylor Equation for tool life evaluation and letting C=100, and n=0.5, calculate the percentage increase in tool life when the cutting speed is reduced by 30%. (6 marks) (c) Distinguish milling process from drilling process. (3 marks) (d) In an ideal orthogonal cutting operation, the depth of cut to is 0.4 mm, the chip thickness after the cut to = 1.1 mm, the rake angle of the cutting tool is 12°. Determine the shear plane angle and the shear strain in the cutting operation. (7 marks)
