Calculate the maximum y direction force for a 40% radial immersion down

milling cut carried out using a three tooth end mill; see Fig. e.4.3. The

material-tool combination gives: kt ¼ 720N=mm2 and kn ¼ 200 N/mm2

(aluminum alloy). Also, b = 2.5 mm and ft = 0.2 mm/tooth. Assume a

rigid cutting tool and workpiece.
