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).
