Effect of Dry Machining on Cutting Force

– Introduction Machining is the most important part of the the manufacturing process. The turning is one of the most commonly employed basic operations in the experimental work of metal cutting. The work material is held in the chuck of a lathe and is rotated. The tool is held rigidly in a tool post and moved at a constant rate along the axis of the feed bar, cutting away a layer of metal to form a desired profile. The components of cutting force acting on the tool are an important aspect of machining….  

Gods of Metal: The Band Metalica

– “Give me fuel, give me fire, give me that which I desire”, if one doesn’t know where this famous lyric has come from, the band Metallica would be the answer. Metallica is a lethal, energetic, up tempo metal band that has been around since October 1, 1981. Screeching of the guitar, double bass pedal of the drums, deep noises of the bass, and a recognizable voice, Metallica is the only band where no band could do it any better. Metallica started out slow, overcame some obstacles and is still rocking out country to country today….  

Metal-Only Lewis Pairs with Transition Metal Lewis Basas

– … The IUPAC definition of dative bonds indicates two possible methods of identifying dative bonds. The first is whether one of the atoms is an acceptor and the other atom is a donor of elecetrons. The other is if the minimum-energy rupture pathway is heterolytic. Both methods have their flaws; the first is that Lewis base fragments may act in such a way or may be unstable if not in the presence of a Lewis acid. The second being that the gas-phase minimum-energy rupture concept requires that complexes be treated computationally but very few of these complexes have been calculated….  

Why We Use Metal Sheets

– For as long as people have had the means, metal has been beaten into sheets and used for architectural purposes, from roof coverings to sewer pipes. In the late seventeenth century, this hand-hammering process was later replaced by large “rotating iron cylinders” which pressed metal into flattened sheets (Simpson 31). These water-powered rolling mills allowed for more uniform sheets as well as a less laborious and time-consuming process. The sheets were allowed to be thinner, which was advantageous when creating smaller details, such as gutters and roofing….  

A Brief History of Heavy Metal

– Many people view heavy metal as loud, obnoxious music played by people with no talent and listened to by a bunch of head banging punks who do not like listening to “real music”. But many people do not know anything about heavy metal or its history. Heavy metal is a term widely characterizing a style of music that is loud, aggressive, and extremely popular. Heavy metal is extremely diverse and has many sub genres which is why not all heavy metal bands sound the same. Many different heavy metal bands and sub genres originate from all over the world….
