| Module Learning Outcomes Assessed: 2. Employ the principles of solidification, diffusion and solid state deformation to the relevant manufacturing process. 3. Develop a broad knowledge base of the various types of manufacturing processes (e.g. casting technology, forming and shaping processes, material removing processes and joining processes). 5. Evaluate manufacturing processes on the basis of cost, accuracy and lead time to form judgments about their applicability to given manufacturing situations, including considerations of environmental and end of life costs of products. 6. Evaluate common engineering materials on the basis of mechanical and physical properties, cost and manufacturing properties, and form judgments about their applicability to given product functional requirements. |
| Task and Mark distribution: You are given a list consisting of few “classes of materials” including aluminium alloys, cast iron, magnesium alloys and composite material. You are asked to choose a material from this list for a cylinder head (for a four-cylinder petrol car) to be made later this year, or early next year. A schematic diagram (Figure 1) shows a design of a typical cylinder head. Figure 2 presents how this component is placed in relation to an internal combustion engine. Figure 1. a schematic diagram of a cylinder head Figure 2: parts of an internal combustion engine. Scope: Students are asked to prepare a case study presenting a suitable material for the cylinder head. Now you are given a different component (presented in Fig. 3), and you are asked to identify suitable manufacturing process(s) by which the component in Fig. 3 will be manufactured. Specification is presented in the Figure 3’s caption. When producing the report, scientific reasons for the selected process(s) should be included. The areas that are needed to be covered in the report are listed in Table 1. Figure 3. A schematic diagram of a manifold jacket (hollow-shaped component) used in jet engines which requires working at high temperatures at around 400-500°C. The material to be used is usually made of nickel or iron-nickel alloy. It weights about 6.7 kg and minimum thickness in 2-4.5 mm, tolerance of 0.1mm, surface roughness requirement is just under 20 micrometres, the number of component required is 15. Deliverables and Mark Allocation A 5 page (A4) report is expected, with a minimum font size 10. Line spacing should be no more than 1.5 lines. This page limit excludes figures, tables, graphs, list of references and appendices. Your report can be longer than 5 sides (e.g. due to figures, graphs & tables) but no more than 5 sides of text in report main body. Please ensure that you provide a list of the academic references at the end of the work; use CU Harvard system for in-text citation and the listing of the references. Text should be written for academic audience; hence, ensure you use the relevant rules (e.g. use of third person, passive format). Appendices should be used for non-essential diagrams and information if necessary. The report is expected to have a structure as defined by the Sections described below. In addition, the value ascribed to the report sections and the report quality are shown as percentages of relative value against each portion of the report below in Table 1: Deliverables and Mark Allocation Table 1 Section Subject Matter Relative Value 1 Component Function and Operating Environment 1a Review the function (or role) of the component (given in Fig 1) including the context of the larger assembly to which it belongs. 6% 1b Outline the service conditions that are caused by the component’s function and the environment in which it functions which the component will be designed to withstand (e.g., types of stresses, temperatures, service atmospheres etc.). 9% 2 Material Properties and Selection 2a Discuss and justify the material property requirements for the component in Fig. 1 by relating the material property requirements to the service conditions & requirements identified in your answer to section 1b. This should include few quantitative values of the required properties. 10% 2b Identify the material or materials used to make the component (given in Fig 1) (ignore any small brackets, bolts and other small components attached to the component). Chemical content of the main constituents should be included. Using the identified material properties from question 2a, perform a material selection analysis (using CES software/ or alternative database) to justify the material selected for the component. Use relevant performance indices to aid your selection where possible. Hence justify the material chosen for the component. 12% 2c Should there be any differences in the required properties and hence the chosen material if a diesel engine was to be manufactured? Explain. 6% 3 Alternative Materials 3a Perform materials selection procedure if the same component given in Fig 1 is to be used for a high-performance racing car where lower quantity (e.g. 15) of such component is required. List possible materials that could be used under such condition. In your selection refer to your CES/ database analysis from Section 2b and compare properties. Select what you believe to be the “best” material to be used in a racing car and explain why. 9% 4 Component Manufacturing Route 4a Manufacturing route selection: Discuss several potential suitable manufacturing routes for the component given in Fig 3 (manifold jacket). Perform a CES process selection exercise (or use any process database) relevant to the component and its material to downselect and justify a final process route. Note: In your selection and also discussion around the selection consider and compare casting, additive manufacturing, and/or powder metallurgy and/or machining. Tip: Carefully consider the shape and the thickness of component when choosing the process. 11% 4b Review & explain the selected manufacturing route in detail. 10% 4c You are told that one or two of additive manufacturing processes can be used to make the component in Fig 3. Name the advantages of using additive manufacturing in cases similar to this case. 7% Other Report structure presentation, referencing & technical writing style, adherence to the requirements contained in this document. 20% Total 100% Delivery Schedule Refer to the 102EMM Moodle page for information pertaining to delivery of your report. A time will be defined for the last opportunity to submit your report. After this time the submission will be rejected unless an extension is granted. Late work will only be accepted with an officially granted extension from assessment office (this will require legitimate reasons, e.g. medical) Turnitin software will be used to check for ensure originality and value. DO NOT COPY FROM WEB SITES, TECHNICAL REPORTS OR TEXT BOOKS, SUCH BEHAVIOUR IS PLAGIARISM AND THEREFORE UNACCEPTABLE. The penalties for plagiarism can be severe and have extreme consequences for your future at the University. Hints and Tips • READ THIS DOCUMENT THOROUGHLY SEVERAL TIMES. • Do not leave asking questions or report submission until the last moment. • Write report in the “3rd person” (standard report writing style) • Please make sure your work is properly referenced. • References, figures, tables and graphs must be cited within the text at the relevant place as well as listed in full in your Appendix (reference section). • Structure the report as per the sections in the scope. Do not combine sections. • If you don’t attempt a particular section, you will get a zero for that section. Details of how, where and when to submit your report will be given on the 102EMM Moodle page. Late submissions will not be accepted unless accompanied by an officially granted extension from Registry. |
| Notes: You are expected to use the Coventry University Harvard Referencing Style. For support and advice on this students can contact Centre for Academic Writing (CAW). Please notify your registry course support team and module leader for disability support. Any student requiring an extension or deferral should follow the university process as outlined here. The University cannot take responsibility for any coursework lost or corrupted on disks, laptops or personal computer. Students should therefore regularly back-up any work and are advised to save it on the University system. If there are technical or performance issues that prevent students submitting coursework through the online coursework submission system on the day of a coursework deadline, an appropriate extension to the coursework submission deadline will be agreed. This extension will normally be 24 hours or the next working day if the deadline falls on a Friday or over the weekend period. This will be communicated via your Module Leader. You are encouraged to check the originality of your work by using the draft Turnitin links on your Moodle Web. Collusion between students (where sections of your work are similar to the work submitted by other students in this or previous module cohorts) is taken extremely seriously and will be reported to the academic conduct panel. This applies to both courseworks and exam answers. A marked difference between your writing style, knowledge and skill level demonstrated in class discussion, any test conditions and that demonstrated in a coursework assignment may result in you having to undertake a Viva Voce in order to prove the coursework assignment is entirely your own work. If you make use of the services of a proof reader in your work, you must keep your original version and make it available as a demonstration of your written efforts. You must not submit work for assessment that you have already submitted (partially or in full), either for your current course or for another qualification of this university, unless this is specifically provided for in your assignment brief or specific course or module information. Where earlier work by you is citable, ie. it has already been published/submitted, you must reference it clearly. Identical pieces of work submitted concurrently will also be considered to be self-plagiarism. |
