Appendix C.<br />
Extrusion screw manufacturing details<br />
As described in the report, the final extrusion screw<br />
was machined by a CNC lathe, using a G-code script.<br />
The script was created in WinCAM, a pieces of<br />
software that comes with the EMCO lathe that was<br />
used. More information can be found at:<br />
http://www.emco.at/en/win_cam.htm<br />
The script itself is written below:<br />

The first group of codes are standard written by<br />
WinCAM, the software in which the program is<br />
written. The second group of codes needs some<br />
explanation. The next rules represent the parameters<br />
for the screw, like depth and pitch.<br />

N0065<br />
R20=Pitch<br />
R21= Start of screw thread in X-direction<br />
R22= Start of screw thread in de Z-direction<br />
