A CNC milling operation is carried out by moving the tool from the point A to point B in anti-clockwise direction to cut a slot of quarter circle with center at C, as shown. The coordinates of the points A and B are (0,0) and (10,10), respectively. All dimensions are in mm. If the feed rate at point P along x-axis is 6 mm/min, then the feed rate (in mm/min) at point P along y-axis is ______ . (Rounded off to 1 decimal place)

A cylindrical workpiece is turned using two different tools. Tool 1 has zero nose radius; the side and end cutting edge angles are \(20^\circ\) and \(10^\circ\), respectively. Tool 2 has a 0.5 mm nose radius. Both tools machine at a feed of \(0.2\ \text{mm/rev}\). The ratio of the ideal maximum height of unevenness on the surface produced by Tool 1 to that produced by Tool 2 is \(\underline{\hspace{2cm}}\) (round off to one decimal place).
