Research ArticleOpen accessIn the abstractMicrostructure Affecting Cutting Quality in Fine Blanking ProcessBopit BubphachotProblem statement: Fine blanking process is a high precision process and worldwide in developed countries. Since specimen does not occur fracture on the cutting edge and it is not necessary to decorate again in the finishing process for the fine blanking which can be reduced some operation steps. For example, if chain wheel of motorcycle is produced by conventional blanking, … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,461 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 · 8,384 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Performance of Uncoated Tungsten Carbide Insert in End Milling Titanium Alloy Ti-6Al 4V through Work Piece PreheatingL. Turnad Ginta, Mohd Amri Lajis, A.K.M. Nurul AminProblem statement: Titanium alloys have been used widely in the aerospace, chemical and petroleum industry because of their high specific strength, fracture resistance and superior resistance to corrosion. Titanium alloys have a very high strength-to-weight ratio making them very suitable for aircraft engines and airframe manufacture. Approach: The use of titanium alloys as engine component materials is due to their … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,905 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAir-Cooling Used For Metal CuttingBrian Boswell, Behrad Katirachi, Tilak T ChandratillekeAir-cooling and dry machining are both being trialled as possible solutions to the metal cutting industry’s long running problems of extending tool life, reducing tool failure and minimising the heat generation at the tool tip. To date, large amounts of expensive coolant which cause both environmental damage and health hazards have had to be used. The introduction of dry machining … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 8,215 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Tomato Geometries and Air Temperature on the Drying Behavior of Plum TomatoM.S. Brooks, N.H. Abou El-Hana, A.E. GhalyThe drying behavior of plum tomatoes as affected by drying temperature and tomato pieces geometry was investigated. The tomato was cut into halves, quarters and eighths and dried at temperatures of 55 and 65°C. During drying, the moisture content followed an exponential decay curve with R2>0.98. The time required to achieve the critical moisture content for storage (15%) for the … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,107 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Application of Local Wisdom for Production of Condiment Isan' Food Ingredient into CommercialNitchapanrawee PhengpholProblem statement: The problem of the research derives from a lack of study and understanding about the production of condiment Isan food and ingredients being introduced into commercial, even though Isan food is popular among consumers widespread both inside and outside the country. The government introduced a policy to expand trade to create an export value of Isan products. The … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 10 Oct 2011 · 7,221 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,106 accessesView PDF Cite
