Surface Roughness Modeling in Precision Turning of Aluminium by Polycrystalline Diamond Tool Using Response Surface Methodology
Diamond, because of its high modulus of elasticity, chemical inertness and exceptionally high hardness, is ideal for obtaining fine surface finish and accuracy. Today’s requirement of high precision parts like magnetic memory device, laser equipment, electrostatic copier, printing machine, etc., made of non-ferrous materials, such as aluminum, copper and resin demands very high surface finish. ...
متن کاملSurface Generation in Ultra Precision Single Point Diamond Turning of Aluminum
INTRODUCTION Ultra precision single point diamond turning is a very promising tool based manufacturing technology because of its reliability, productivity and wide range of applications. However, with the reduction in cutting dimensions compared to traditional precision machining, the process physics differs substantially. This is largely because of size effects and increased surface finish exp...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
Effect of Cyclotrimethylenetrinitramine on the WetSynthesis of Ultra-nanocrystalline Diamond
The Ultra-nanocrystalline diamond (UNCD) was synthesized by the detonation of a high explosive mixture in water confinement. The presence of a diamond phase was revealed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). X-ray line broadening (XRLB) was used to evaluate the peak profiles of diamond nanoparticles and their corresponding average crystallite sizes. The micro st...
متن کاملcritical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
