Orthogonal turning is performed on a cylindrical work piece with shear strength of 250Mpa. The following conditions are used: cutting velocity is 180m/min, feed is 0.2mm/rev, depth of cut is 3mm, chip thickness ratio is 0.5. the orthogonal rake angle is 7deg. Apply Merchants theory for analysis.
The shear plane angle (in degrees) and the shear force respectively are
(a) 22.65 ; 150N (b) 22.65; 320N
(c) 28; 400N (d) 28; 320N
The cutting and frictional forces respectively are
(a) 568N ; 387N (b) 565N ; 381N
(c) 202N ; 120N (d) 202N ; 356N
