Research ArticleOpen accessEvery word in the titleA Study of Parameters Relationship to Backcutting Phenomena During High Speed End Milling of AISI H13Erry Yulian T. Adesta, Afifah Mohd Ali, Delvis Agusman et al.Problem statement: In die and mold industries, surface roughness of the dies and molds produced will determine the end product quality. Therefore, the desired finish surface was specified and the appropriate processes were selected to reach the required quality. Among many contributors to surface quality problem, backcutting is one of the factors influencing the surface roughness. Approach: The aim for … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,509 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEffect of a Phytomineral Complex and an Enzyme Preparation on the Absorption of Nutrients and the Energy Balance of Calves' DietEvgeniia Erenko, Aleksandr Ovchinnikov, Marat Aubakirov et al.Cost-effective animal husbandry directly depends on the correct breeding of replacement young animals using diets corresponding to the feeding rate for all nutrition elements of the detailed system. Critical to these diets are biogenic elements, pivotal in enzymatic reactions and immune defense. However, specifics on enhancing nutrient absorption through dietary supplements remain underexplored, particularly in the context of calves' preweaning … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 12 Jun 2024 · 4,592 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Process Parameters on Electrical Discharge Machined Job Surface IntegrityA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) is the most widely used non conventional machining process for removing material from workpiece by means of a series of repeated electric discharges. Electrical Discharge milling (ED-milling) is an emerging technology where a cylindrical tool electrode follows a programmed path in order to obtain the desired shape of a part. During machining of metals … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,584 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHot Machining of Hardened Steels with Coated Carbide InsertsM. A. Lajis, A. K.M.N. Amin, A. N.M. Karim et al.Problem statement: The benefits of easier manufacture of hardened steel components can be substantial in terms of reduced machining costs and lead times compared to the traditional route involving machining of the annealed state followed by heat treatment, grinding/EDM and manual finishing. But machinability of hard material through conventional machining is hindered due to excessive wear of the cutting tools … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,378 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA 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 PDF Cite

Research ArticleOpen accessIn the abstractSurface 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 PDF Cite
