INTRODUCTIONThe material and manufacturing engineering is defined as the branch of engineeringwhich analyses the production methodologies, application and properties of material used withinmanufacturing and development of products. It enables to control, predict and to enhance theproperties of material so that it can be used effectively for development of advanced products(Black and Kohser, 2017). The study is considered as essential for making the developmentprocess effective in terms of cost and performance. The report will discuss the characteristics ofbikes by using the concepts and methodologies of material science and engineering. It willdescribe the functionality of bikes and the material specifications in their manufacturing process.The document will also discuss the primary form of material at the initial phases ofprocessing and how additional treatment methods can affect the performance and structure of thebikes. It will describe the manufacturing operational path used by the industries and varioustesting and quality assurance processes to guarantee the quality of products formed. Thedocument will also explain the environmental issues associated with production and processingof bikes. It will explore the alternative methods and materials which can be used to achieve thesustainability and other performance or cost related advantages.PRODUCT DESCRIPTION AND FUNCTIONBikes are two or three wheeled vehicles which can be driven by humans or motors. Bikescan be used for long distance travelling, sports, cruising and commuting activities. Bicycles andmotorcycles are commonly known as the term bike. Bicycles are driven by pedals and can bemotor or human powered. On the other hand motorcycles are driven by fuels and are verypopular due to their low prices and higher performance in terms of speed and comfort.MATERIAL SPECIFICATIONS AND RATIONALE FOR THEIR SELECTIONThe two components of bikes which are made up of same material can have differentstrength and properties depending upon the composition, shape, assembly and manipulation ofmaterial (Kalpakjian, Vijai Sekar and Schmid, 2014). Usually for manufacturing process of bikesa blend of materials like aluminium, steel, carbon fibre and titanium is used.Aluminium:It is one of the most widely used material in the construction of bike frame. It isknown as the lighter material in comparison to other frame materials used in bikes. It can showgreat diversity in shape, assembly and quality. The resistance to rust gives it an additional1
advantage over steel. Pure aluminium cannot provide the sufficient material strength required forbikes thus it is used in alloy form with silicon, zinc and magnesium. The stiffness andlightweight aluminium frames makes it easy for bikes to comfortably ride on rough roads aswell.Aluminiumhas more stiffness and thus it can result in harsher rides. It is preferred by thetrack racers because they require rigidity in their bike rides. On the other hand the brittle natureof aluminium make this type of bikes more vulnerable to damages. The inappropriate dent inaluminium frame can also make ride unsafe.Steel:In most of the bikes frame is constructed by steel. The easy bending and shapingcapabilities of steel make it easy for the bike manufacturers to use variety of steel tubes for theprocessing. Especially in manufacturing of bicycles the needs of cyclists can be fulfilled bymyriad assembly and this is easily applicable in steel (Collins, Leen and Gibson, 2016). The steelframes in bikes provide high durability, quality rides and ability to easily repair which makesbike more affordable. Steel can be mould to any shape and is stronger than carbon fibre oraluminium. The entry level frames of steel in bikes cost effective and can reduce themanufacturing cost but they are considered as less sophisticated. On the other hand though highquality steel frames in bike increases the manufacturing cost but it makes the bike efficient interms of comfort and responsiveness.The durability of steel is unbeatable by any other materialthus even dent, bends, scratches does not affect the structural integrity of the steel based bikeframes.Carbon fibre:This material does not belong to metal group and is new to the bike manufacturingmaterial. The use of this material can give bike attractive shape, impervious behaviour towardscorrosion, durability, stiffness and easy manipulation. The carbon frames require fabric andresins to manufacture and thus it is also costly material and is used by limited manufacturers.Along with fine handling it has great ability to manage and absorb shocks. Under stress it can beeasily damaged and it can be difficult for manufacturers to assessed the damage due to heavycrashes (Wilhoit and Kisselburgh, 2017).Titanium:The bike frames made up by Titanium are stronger and long lasting. Thus, they areconsidered as the most expensive material for bike frames. It also provides facility of electrichandling and gives the best performance in terms of weight, comfort similar to its rivalrymaterials aluminium and steel. The use of these frames can increase the manufacturing cost very2
