In the rolling lab we measured the following conditions:
R = 32.25; % roller radius (mm)
Nr = 30; % roll rotational speed inrpm
A 8-pass flat rolling process was performed with one set ofworkpiece dimensional data of length l, width w, and thickness t,measured as below:
(with the first set of data for initial solder wire, and therests are the outlet dimensions of each pass)
l = [37.85 39.55 41.39 45.96 50.1959.83 79.64 127.5 260.0]; %length (mm)
w = [2.92 3.22 3.51 3.63 3.76 4.024.21 4.30 4.35]; %width (mm)
h = [2.92 2.38 2.059 1.672 1.470 1.1260.802 0.468 0.177]; %thickness (mm)
The total rolling time for each pass is:
t = [0.35 0.39 0.44 0.48 0.58 0.781.25 2.55];
Express the x-component of thevelocities of the roll vr(x) and the workpiece metalvm(x) as a function of x (where x is in rollingdirection and x=0 at the outlet section), for each pass, and plotvr(x) and vm(x) for each pass in onefigure
