a) Describe five different manufacturing methods, including their corresponding characteristics and applications. Give exemplified products made from each manufacturing method.(5 marks) b) What are the cutting parameters? Give their definitions.

How do they affect different chip formation? Give examples for each kind of chip during the cutting process. c) For a turning operation, calculate the rotational speed if the workpiece diameter isD and the cutting speed is V. If the depth of cut used was di, the process is completed in n identical passes, what is the final diameter? Use the parameters specified in the following table for calculation. d) How is the normal surface roughness formed? What are the influencing factors and improvement measures?(5 marks)
