“…The experiments are carried out as per the design matrix and results are obtained. The results are further transformed into signal-to-noise ratios (S/N ratio), these ratios are logarithmic functions of desired output and serve as objective functions for optimization, which help in data analysis and prediction of optimum results [13,14]. The S/N ratio provides a measure of the impact of noise factors on performance.…”

EN31 is a high carbon steel, used in manufacturing bearings, punches and gauges because of its better hardness. Heat treatment is one of the major process adopted to improve microstructural and mechanical properties of high carbon steels. The present investigation aims to improve hardness of EN31 high carbon steel through heat treatment. Parameters considered during this investigation were austenization temperature, soaking time, temper temperature and temper time. Microstructure examination was carried out to confirm the phases of heat treated EN31. Taguchi’s orthogonal approach was adopted to minimize the number of experimental runs. Influence of each parameter on the hardness was analyzed. The levels of each parameter were identified that maximize the hardness through S/N ratio. Identified optimal levels of parameters are 900 °C austenization temperature, 30 min soaking time, 150 °C temper temperature and 10 min temper time. A regression model for hardness has been established. Analysis of variance test was used to identify the significant parameters. Finally, the results were validated through confirmation experiments.

Abstract. Surface finish and dimensional accuracy play a vital role in manufacturing engineering applications. Grinding is one of the most important methods for producing a better surface quality. This paper describes a study of the influences of cutting parameters such as table speed, depth of cut and feed rate on surface finish of AISI 2080 steels, based on the Taguchi (L27) method. The experimental results showed that the table speed was the machining parameter, which had a greater effect on the surface finish, followed by depth of cut, whereas feed rate showed no significant effect. Analysis of variance indicated that a better surface finish was obtained at 190 m/min speed, 0.003 mm depth of cut and 0.08 mm/rev feed rate. IntroductionIn the manufacturing industry, surface quality is one of the most important parametres in order to evaluate the product quality. A better surface finish is desired in many engineering applications because it minimize friction and wear, improved the fatigue strength, corrosion resistance, precision fits, thereby enhancing the operating hours of machined parts. Obtaining the better surface finish in any machining processes such as lathe, milling, drilling and grinding depends on various parameters like machining parameters, tool and workpiece material properties and cutting conditions. In grinding operation, the surface roughness also depends on cutting speed, feed rate, depth of cut, lubrication, machine vibrations etc. However, an appropriate selection of the grinding parametres is more important [1,2,3].Taguchi designs are used to analyze and optimize the machining parametres because a desirable product quality can be achieved with system and parametric design [4,5]. Several researchers have conducted on development of matheamatical models of surface roughnesses for different steels such as carbon steel [6], En8 steel [7], En18 steel [8], AISI 1040 [9], AISI 4140 [10,11] and use of oil effect [12] using a Taguchi technique. There are numbers of studies carried out on different steels by using the statistical method [5][6][7][8][9][10][11]. However, no study is performed on grinding of AISI 2080 steel with statistically and experimentally. Therefore, the aim of the present work was to investigate the surface finish of under different girinding conditions. The Taguchi L27 (3 13 ) method and ANOVA were adopted to identify the effect of process parameters on the surface finish of tested materials.
