Report on Manufacturing of Mechanical Parts_1
AbstractAdditive Manufacturing (AM) is being displayed as a prototype for manufacturing things andthat involves the fabric frame zones and the past frame zone. It can be used in case oftraditional machinery products. Selective Laser Melting (SLM) is basically an AM method and itutilises the laser to check the metal powders to form the 3-D CAD data. In the report, themanufacturing of the mechanical parts of the Ti– 6Al–4V alloy handled by SLM and scanningstrategies have been elaborated in the report. The martensitic phase is being showcased in thereport and the epitaxial growth has evolved. The heat treatment and the scanning strategiesbased on the mechanical properties have been detailed in the report.

1.IntroductionThe primary objective of the project is to examine the impact of the manufacturing directionand the scanning design on the machinery parts of the SLM parts. The samples of Ti-6AI-4V were beingprinted utilising various scanning techniques and it contains the meander and the stripes along withnumerous process parameters. The annealing has been performed in both alpha and the beta phaseswith varying temperatures to enhance the ductility. This project will highlight different characteristics ofTitanium microstructure and the Titanium microstructure has been manufactured using additive metals.The titanic metal has got some unique characteristics- they are highly resistant to corrosion, they arelightweight and they have the high strength. For these entire unique properties titanium, alloy or thetitanium metal can be used in aero scopes applications. The alloy is cost effective and has got thestructural efficiency in the aero scope technology. This titanium alloy can prove beneficial and fruitful tothose who want to embellish the aforesaid technology.

Figure. 1: Experimentation on SLM machineSelective Laser Melting is the Am methodology and this methodology is known to utilisethe laser to the utmost to diminish the metal powders and that assists them to form elementsfrom 3-D CAD data. The metal powder is softened by means of high crammed ytterbium fibrelaser. The SLM initiative is taking at the time of applying a layer of powder at the constructionlevel. Ti-6Al-4V is the alpha-beta titanium alloy which caters the alpha-beta titanium alloy thatfeatures the corrosion resistance, high tensile strength and the low weight ratio. Ti-6Al-4V haswidely used titanium alloys. The materials are used in manufacturing the vehicles, it is also usedin the manufacturing of the marine apparatus.2.Literature reviewTitanium metal is an advanced metal that has got some unique features andcharacteristics. The titanium metal has the high strength as well as the high melting point that iswhy multiple arguments have been made on how to manufacture the aforesaid metal. Thereare various techniques and the procedures to fabricate the titanium metal but the metal can beused in a limited way due to the high cost of titanium metal and also it is not used in general inall metal industry. SLM has been particularly chosen for the project as because it has someexcellent facilities to offer, the use of this metal can lessen the steps in production and thushigher efficiency can be gained by the usage of the material. The transition metals, for example, the silicide and the carbides have got advancedcharacteristics, they have environmental resistance, low density and stiffness, but there is onlyone issue. The issue is that these silicide and carbides have a relatively low melting point. Bymeans of fabricating titanium substrate with silicon carbide by melting the Ti-SiC powdermixture to a certain extent, the main reason for choosing the laser technique is to relate
