Title:
Optimization of squeeze cast process parameters on
hardness of LM20 alloy using Taguchi method
Authors:
The near-net shape manufacturing ability of the squeeze
casting process have greater potential to yield higher
hardness values provided the squeeze cast technical
parameters are accurately controlled. In squeeze
casting, squeeze pressure, pouring and die temperature
are considered as the most important process parameters
that critically influence on the hardness values. So in
the present work, the cost-effective taguchi method has
been utilized to perform experiments, study and analyze
the effects and to estimate the percent contributions of
each individual process parameters on the measured
hardness values. Three levels for each process
parameters are considered and L9 orthogonal array has
been selected to perform the experiments. The suggested
optimal process parameter levels using taguchi analysis
are capable of giving higher hardness experimental
values. Hence taguchi parametric design is an effective
method in deciding the optimal process parameter levels
by reducing manufacturing cost with lesser number of
experiments.
