Abstract:
The aim of this work is to identify relationships between the input variables
and the process response and to develop predictive models that can be used in
the design of new friction surfacing applications. Moreover to investigate the
use of standard CNC machines for friction surfacing. The experimental design
techniques and response surface methodology were used to investigate and select
the combination of factor levels that produced the optimal response. The main
effect of the velocity ratio obtained by dividing the feed rate of mechtrode
with traverse rate of substrate was observed to be the most significant factor
on the process response. Based on the results of optimisation it was observed
that the lower to intermediate levels of rotational speed and intermediate to
higher levels of velocity ratio produced good coating quality. (C) 2010 Elsevier
