of stiffness axis relative to the cutting forces, result in a significance increase in dynamic stability. Another technique involves making solid bars with materials having high youngs modulus or high damping materials. Typical examples include sintered tungsten carbide and sintered tungsten carbide alloyed with copper and nickel. These materials are expensive but give stable machining for l/ratios up to

dependent on the properties of engineering materials. In aircraft and aerospace industries, a union of opposites i.e., lightweight in combination with high stiffness is demanded. In pressure vessels technology, high strength and corrosion resistance are both prerequisites for efficient operation. Whenever a designer faces such situations composite materials provide an efficient solution to such problems. The flexibility that can be achieved with composite materials is immense. Merely by changing

The materials, equipment, and processes used in the metal stamping industry have proven to be less costly than the original methods of forming metals and alloys into definite shapes. Metal stamping is the method of bending, clipping, and molding sheet metal or coil metal by stamping and pressing the material into the desired forms. The shaped metal is plated with nickel, tin, or some other metallic elements to protect it from corrosion. The most commonly used metals are steel, aluminum, zinc, and

application. The plastic which is able to resist any breakage under tensile strength is preferred. These can be achieved by exert the plastic films with the characteristics like high tensile strength and high degree of elongation. A packaging material or plastic material which is brittle in natures, and with poor tensile strength and flexibility will have a minimal use in food packaging industry. Basically, tensile strength can be defined as the maximum tensile stress that the plastic can sustain without

Cast Plaques Cast plaques can be made from bronze, aluminum, brass or any other material you prefer. They are a durable sign option for a variety of purposes. They are generally installed on walls of any material, though they are also suitable for statues or external buildings. Custom memorial plaques are the perfect dedication to any building or as an award for recognition. Additionally, cast plaques can also be used as a diploma or certificate, to memorialize an announcement or even as signage

The Life Cycle of a Plastic Bottle The average American consumes 167 bottles of water each year. There are many steps involved in making a bottle of water and throughout the process many natural resources are used. Make a note of how many times the bottle is transported throughout the process and remember that transportation also uses gasoline and releases a lot of carbon dioxide into the air which contributes to air pollution. First, the oil is extracted from the earth Then the oil is

Study Structural materials can be categorized in many ways in many different ways. One of the most common is by the nature of their failure. Materials, such as steel, after reaching their elastic limit, deform plastically before failing. Such materials, where reasonably large plastic strains are observed, are broadly categorized as ductile. On the other hand, those materials that exhibit little or no plasticity are in contrast termed brittle. In structural design, ductile materials are usually preferred

1] Introduction: A cold seal adhesive is a material that has good adhesion to itself at ambient temperatures, a property that is often referred to as “self-adhesion”, “auto adhesion”, or “autohesion”[1]. Cold seal adhesive comprise a special class of pressure-sensitive adhesives which possess the capability of forming a strong bond to themselves and hence also known as cohesives. Cold-seal adhesives are an established class of commercial adhesives characterized by being coated onto plastic films
