a) Your manufacturing process requires to drill a 300 mm deep hole with a diameter of 30.0 mm on titanium alloy workpiece. Propose a suitable process in NTM that can create more output than surface quality. Justify your answer. (5 marks) b) FIGURE Q2b shows a circular nickel alloy disc with a 10mm diameter and a 0.5mm thickness. To create multiple holes, your process has to do micro-drilling utilizing the ECM process. Sketch a proper schematic of your tool (electrode) that will result a shorter machining time. In your opinion, what parameters can be controlled to improve machining time.
