| Description: | <p>A study of the production Iine process of wire manufacturing was made and a mathematical model of some aspects of the physical process then constructed. Using this model a computer program was written to simulate the process and hence predict the statistical distribution of wire strength. Additionall y certain aspects of the wire drawins process are optimized so as to impart desirable metallurgical characteristics to the wire.</p> <p>The simulation is achieved by two different techniques, in cases where the random variables are mutually independent the method of 'Transformation of Variables' is used, and in the more complex case of non-independent variables a 'Monte Carlo' simulation is performed.</p> <p>The area reduction of the wire due to reduction of successive die sizes, is optimized with respect to the ideal process when subjected to manufacturing machinery limitations. The optimization technique used is basically a 'Direct Search' modified to overcome the inherent inabil ity of the method to move toward optimality in the face of certain constraints.</p> |
