Application of response surface methodology for the optimisation of microfriction surfacing process

摘要

The aim of this work is to identify relationships between the input variablesand the process response and to develop predictive models that can be used inthe design of new friction surfacing applications. Moreover to investigate theuse of standard CNC machines for friction surfacing. The experimental designtechniques and response surface methodology were used to investigate and selectthe combination of factor levels that produced the optimal response. The maineffect of the velocity ratio obtained by dividing the feed rate of mechtrodewith traverse rate of substrate was observed to be the most significant factoron the process response. Based on the results of optimisation it was observedthat the lower to intermediate levels of rotational speed and intermediate tohigher levels of velocity ratio produced good coating quality.
