Investigating the Effects of Varying Proportions of Waxes in Wax Mix on Surface Roughness and Optimization by Taguchi Method

Abstract:

In the present work, an attempt has been made to produce a wax blend which could offer a better surface finish. Experiments were conducted with different types of waxes namely paraffin wax, bees wax, montan wax, carnabua wax and ceresin wax by varying their proportions. In each case the surface roughness of wax pattern was determined. The experimental data obtained were used to optimize the quantity of the waxes to form a blend having minimum surface roughness. The effect of varying proportions of the aforesaid waxes on the surface roughness of the wax blends was investigated. Taguchi method was used to optimize the required composition of the waxes. Taguchi method has successfully suggested the required proportions of the aforesaid waxes for the blend which could offer the minimum surface roughness.
