Research ArticleOpen accessPhrase in the titleParametric Deduction Optimization for Surface RoughnessTian-Syung LanProblem statement: Surface roughness is a major consideration in modern Computer Numerical Control (CNC) turning industry. Most existing optimization researches for CNC finish turning were either accomplished within certain manufacturing circumstances, or achieved through numerous equipment operations. Therefore, a general deduction optimization scheme is deemed to be necessary for the industry. Approach: In this study, four parameters (cutting depth, feed … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 7,440 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleOptimization of Cutting Parameters Based on Surface Roughness and Assistance of Workpiece Surface Temperature in Turning ProcessAdeel H. Suhail, N. Ismail, S. V. Wong, N. A. Abdul JalilProblem statement: In machining operation, the quality of surface finish is an important requirement for many turned workpieces. Thus, the choice of optimized cutting parameters is very important for controlling the required surface quality. Approach: The focus of present experimental study is to optimize the cutting parameters using two performance measures, workpiece surface temperature and surface roughness. Optimal cutting parameters … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 12,941 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Note on “Surface Roughness Prediction Model in Machining of Carbon Steel by PVD Coated Cutting Tools”Godfrey C. OnwuboluAn article published in this journal by Sahin and Motorcu[1] developed a surface roughness model based on the response surface method, multiplicative-logarithmically linearized approach for determination of the cutting parameters in turning of AISI 1040 carbon steel. Their published results for the surface roughness show that it appears Sahin and Motorcu[1] have obtained wrong constants (C, m, n, p), thereby … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,248 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleModeling and Analysis of MRR, EWR and Surface Roughness in EDM Milling through Response Surface MethodologyA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) has grown over the last few decades from a novelty to a mainstream manufacturing process. Though, EDM process is very demanding but the mechanism of the process is complex and far from completely understood. It is difficult to establish a model that can accurately predict the performance by correlating the process parameters. The optimum … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 9,606 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleNew (Digital) Technique for Areal Measurements of Stonewall Surface RoughnessMary J. ThornbushThis study revisits a method introduced in the 1990 s that was deployed to measure surface roughness through profiles on rock blocks. Measurements were originally taken directly in the field using a micro-roughness meter or a simple profile gauge. The roughness index was obtained in the "deviograms" method utilizing the standard deviation of differences between 38 adjacent height measurements. The … …Current Research in Geoscience, Vol. 4, Issue 2 · 14 Jan 2015 · 6,857 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleSurface Roughness Prediction Model in Machining of Carbon Steel by PCD Coated Cutting ToolsYusuf Sahin, A. Riza MotorcuThe surface roughness model in the turning of AISI 1040 carbon steel was developed in terms of cutting speed, feed rate and depth of cut using response surface methodology. Machining tests were carried out using PVD-coated tools under different cutting conditions. The surface roughness equations of cutting tools when machining the carbon steels were achieved by using the experimental data. … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,964 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMachining Performance Study on Metal Matrix Composites-A Response Surface Methodology ApproachA. Srinivasan, R. M. Arunachalam, S. Ramesh, J. S. SenthilkumaarProblem statement: Metal Matrix Composites (MMC) have become a leading material among composite materials and in particular, particle reinforced aluminum MMCs have received considerable attention due to their excellent engineering properties. These materials are known as the difficult-to-machine materials because of the hardness and abrasive nature of reinforcement element-like Alumina (Al2O3). Approach: In this study, an attempt has been made … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 15 Feb 2012 · 8,017 accessesView PDFCite
