Asteel shaft with diameter of d =57 mm is turned with a carbide tool with a side rake angle of αf =-5º, a back rake angle of αp =-5º, and zero approach angle ψr = 0 º. the nose radius of the insert is r =0.8 mm. the radial depth of cut (a =1 mm) is constant. the shear stress, friction angle, and chip ratio are obtained from orthogonal cutting process data as following: = 1400c + 0. + 507 [n/mm2 ] = 33.69 − 12.16c − 0. [degree] = 2.71c + 0. + 0.227 the units are c [mm] and v [m/min]. kte=0.5c+0.02v; kre=0.3c+0.02v; kfe=0.1c+0.02v by using the lecture notes for modeling tuning process write a matlab code to plot the total cutting force components (fx, fy, fz) for varying feed rate (between c= 0.01 mm/rev and c= 0.25 mm/rev) and cutting speeds of v= 100, 150, 200, 250, and 300 m/min.

Write a program that reads a file consisting of students’ test scores in the range 0–200. it should then determine the number of students having scores in each of the following ranges: 0–24, 25–49, 50–74, 75–99, 100–124, 125–149, 150–174, and 175–200. output the score ranges and the number of students. (run your program with the following input data: 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189.)
