Abstract: In the present paper Taguchi|s Methodology has been applied to the Vacuum Assisted Evaporative Pattern Casting (VAEPC) process of Al-7%Si alloy to determine the most influential control factors. In order to evaluate the effect of process parameters such as grain fineness number, time of vibration, degree of vacuum and pouring temperature on percent deviation of VAEPC process castings, the Taguchi parameter design and optimisation approach is used. The results indicate that the grain fineness number, time of vibration, and degree of vacuum are significant. The predicted optimal value of % deviation of castings produced by the VAEPC process is 0.4172. [Received 25 March 2008; Revised 9 January 2009; Accepted 10 April 2009]
