Abstract

In the present study, an approach to model the dimensional accuracy (Δd), for different geometrical shapes, metal type/pouring temperatures in vacuum moulding (VM) have been proposed and applied by using Buckingham’s π-theorem. Three input parameters namely: pouring temperature; geometrical shape and vacuum pressure were selected to give output in form of Δd. This study provides main effects of these variables on Δd and shed light on mechanism of casting accuracy in VM.
