Which of the following statements about surface finish that can be achieved in machining is the most appropriate one?  Assume that the machinery, tools and accessories involved are in good working conditions, operators are skilled and experienced and the relevant operation parameters are correct.Group of answer choicesTo achieve the same surface finish specification (Ra) on a cylindrical part made of mild steel round bar, turning is a better option than grinding. It is because turning can achieve a wide range of surface finish (e.g. from Ra 25µm to Ra 0.025 µm)Drilling produces coarser surface finish than reamingCasting produces finer surface finish than metal cutting, in generalSelecting a lower spindle speed on drilling machine produces a finer hole surface finishIn a drilling operation, select a higher spindle speed for a larger drill bit in order to achieve a finer hole surface finish
