Open up a button menü with a title of: “Wire Drawing Process” and ask for the wire material. It can be “Cu” or “Al”. The user will select one of these;
Open up a button menü with a title of: “Wire diameter at the beginning” and ask for the wire diameter in mm by giving two selections “8 mm” and “10 mm”. The user will select one of these;
Ask the “wire diameter at the end of process (between 1 - 5 mm)” from the command window and user will enter the value from command screen. If the value is out of the range, a messageshould appear “Out of the range! Please input a value between 1 – 5 mm” and continue till the correct value is written;
Determine the wire drawing type (dry or wet) according to the given ‘Rule 1’ below and disply an information such as: “This process includes dry wire drawing between 10 and 5 mm diameters and wet wire drawing between 5 and 3 mm diameters” (info: This sentence is shown when 10mm is selected as beginning diameter and 3 mm is input as the diameter at the end);
Make force calculations using the equation 1 and 2 given below and do not show the results on the screen;
Plot the (1) drawing force – stage number graph and (2) graph by indicating the bars or indicators of curves in different styles and colors. X axis label should be Passes and Y axis label should be Force [N].

Rule 1:
For Cu wire:
d=10mm to 6mm is DRY drawing
d=6mm to 1mm is WET drawing
For Al wire
d=10mm to 4mm is DRY drawing
d=4mm to 1mm is WET drawing
In all passes diameter reduces 1mm by 1mm.
The mean coefficient of friction µ for:
dry draw: µ = 0.05
wet draw: µ = 0.02
Figure 1 The principle of wire drawing.
 1 die, 2 wire
End of Rule 1.
d: diameter of the wire
A: area of the circular cross-section of wire
A0: area at the beginning for each pass
A1: area at the en for each pass
