Abstract
The objective of the spin casting optimization was to achieve “the lower dimensional error, the better” while minimizing the effects of uncontrollable parameters. Spin casting process parameters that may affect the dimensional accuracy of the casting product were identified with the aid of Ishikawa diagram. The disk closing pressure, rotational speed and runner dimensions were selected as the most significant parameters that can cause variations of the quality characteristic. Runner dimensions include the runner length which is the distance between the disk center and the location of the master imprint, and the diameter of the runner cross-section.
The orthogonal array was designed using the selected significant process parameters with the respective ranges of values. Each parameter was analyzed at three levels, the loss function of the “lower-the-better” as defined by Taguchi was used in the analysis of the signal-to-noise (S/N) ratio. The optimum spin casting process parameter combination was obtained using the analysis of the S/N ratio. The level of importance of the process parameters on the dimensional accuracy of the spin casting product was determined using the analysis of variance. The relative importance of the spin casting parameters with respect to the dimensional accuracy was investigated to determine more accurately the optimum combinations of the spin casting process parameters.
