A component having length 100 mm and diameter 9 mm has to be produced from a raw material of 100 mm length and 15 mm diameter using single point cutting tool of side cutting edge angle as 45 on a CNC lathe machine. The maximum depth of cur is 1.5mm The spindle rotates at 1000 rpm and the tool is moving at a speed of 200 mm/min perpendicular to the axis of rotation and an axial speed of 700 mm/min along the axis of rotation Determine

a) Machining time
