Identify the dimension chain, the type of the links and check the nominals. [11 marks] 2. Calculate the tolerances for all non-standard links. [11 marks] 3. Calculate and check the tolerance limits [11 marks]/nYou are required to do an 'Individual Project' by performing deep study of any one type of "Automotive Piston, samples of which are shown in Figure 1a and 1b, using academic literature', product catalogues of renowned manufacturers of such bearings, technical magazines, etc, for its types, classifications, uses, material and methods of manufacturing, and heat treatment techniques applied on ball bearing material for improvement/enhancement of its mechanical properties. The findings of the study are to be submitted as an individual report as per the template given below in Table 1. All the discussions and arguments presented by the student in this task should be supported by appropriate references and be cited in-text in the report. Your report should be between 1500 to 2000 words. Table 1: Tasks and marks distribution of the Report: S. Project Report Section No 1 Introduction Automotive Piston assembly- 2 types, and uses, diagram of the selected piston type Material and manufacturing methods of selected Piston Marks Sub-tasks in the Report 5 15 15 Provide in this sub-section a brief introduction in general about Pistons, the type of mechanical environment/ conditions they face, and their uses/applications. Also inform in this sub-section ONE type of Piston your have selected for rest of the sub-tasks of this assessment. In this sub-section report about all types of automotive pistons with regards to their design features, applications of each type of piston, their uses. Also provide in this sub- section, the diagram of that ONE selected type of Piston, showing all its parts and explaining the function of each part. In this sub-section of the report, discuss the materials and manufacturing methods (from raw material to final finished product) used for the selected Piston and all its parts. The/nMechanical properties and 4 microstructure of selected Piston and its parts Heat treatment of Piston and its 5 parts 6 Conclusions 15 15 10 principle/concept of 'Computerized Material Selection' MUST be used to substantiate your discussion. In this sub-section of the report, discuss the mechanical properties and microstructure of materials used in manufacture of the Piston and Piston Rings. In this sub-section of the report, discuss the improvements in mechanical properties (and microstructure) of the material of the Piston (and its parts) as a result of different heat treatment methods. In this section, provide the conclusion of your study. Using APA 7th edition style of citation and referencing, provide the list of appropriate and current references used for the report and which should also be cited in-text. 7 Citation and referencing 5 Rules & Regulations: All resources should be cited using APA 7 edition referencing style. • The final assignment must have a Title page, Table of Contents, References/bibliography using APA 7 edition referencing style and page numbers. • Title Page must have Assignment Name, Module name, Session, your name, ID, and the name of the faculty. ⚫ Softcopy in MS Word format is to be submitted through Turnitin link on MEC Learn (Moodle). Guidelines: •Assignment must be computer typed. ➤Font Times New Roman ➤Font-Style-Regular Font Size 12 Heading should be with Font Size 14, Bold, Capital and Underline. Explain with suitable diagrams wherever required. Diagrams must be drawn using suitable software or by pencil./nFirst Class Manufacturing Technology & Materials (MECH 0011.1)-Spring 2024-Assessment 3-Session A-QP • Each student has to do the assignment individually / Students have to do the assignment collaboratively and each student should write a brief reflection on their contribution and learnings from group work. • You can refer books in E-Library or use internet resource. But you should not cut and paste material from internet nor provide photocopied material from books. The assignment answers should be in your own words after understanding the matter from the above resources.
