1. Orthogonal Milling--Determine the cutting force (F_c) for the two materials with the following assumptions: Shear strength i. Cast iron-35000 psi ii. Tool steel-80000 psi Friction coefficient of 0.5 2. 10 degree rake angle Chip width (w) =0.15in Uncut chip thickness (t_o) = .001in Thrust force (F_t) is 15% of the cutting force Using the setup from question 1, plot cutting force for uncut chip thicknesses between .001 and .010 in .001 increments (i.e. .001, .002, ..., .010)
