Abstract:

In this paper, the experimental work is done on different materials EN8 Steel and EN38 steel. Chemical etching technique is used for this purpose. These both materials are used for the low pressure dies or plastic dies. For the preparing of these dies the complex parts of dies are to be prepared by chemical etching technique. During the machining with chemical etching technique the overcut area of material is caused. In this experimentation minimum overcut area is concluded for best machining. Analysis of variance (ANOVA) is employed to investigate the influence of time, temperature and concentration on minimum overcut area of the material. The experiments was conducted to varying the parameters of etching process like temperature from 18 Degree Celsius to 22 Degree Celsius, Time from 2 hrs to 6 hrs and concentration 8% to 12% are studied in details according to Taguchi's design of experiments. At last results are analyzed using Taguchi, ANOVA and parametric optimization is done for minimum overcut area of material. From the experimentation, it is concluded that for etching of EN8 steel and EN38 steel, optimum machining condition for minimum overcut area with Time (2hrs), Temperature (18 Degree Celsius), and Concentration (8%).
