Comparisons of Process Capability in Cold Chamber Die Casting of Aluminium Alloy

摘要

The purpose of the present investigations is to study and compare the effect of processing parameters on process capability of cold chamber die casting of Al alloy. The study presented in this paper is based on a previously published macro model (based on Taguchi design). Castings prepared at proposed parametric settings have been studied and compared using X chart, R chart and process capability histogram (for functional validation of the parts). The study suggested significant improvement in dimensional accuracy and process capability (expressed in terms of sigma ‘σ’ limit) at proposed parametric settings.
