Topic: select material

Order Description My part is the cost material (material selection ) for this fixture regarding to the manufacturing process 100 parts Provides three material we will choose it for this fixture and comparing in costs and Properties of Matter (Strength, tolerance, toughness.......,....,) Then provide graph showing this comparing and discuss why choose this material for this fixture . However I uploaded 1-photos for fixture 2-the group assignment with highlight my part. 3-The Note to show you how choose the material. MEDWAY SCHOOL OF ENGINEERING Course: Innovative Manufacturing Processes and Techniques. Level: M Assignment: 2 Title: Design and rapid prototype manufacture of a fixture for a component. Introduction: We have covered various RP techniques in lectures. In this assignment you will work in small groups (3 members per group) to design and manufacture a ‘fixture’ for a component. The fixture is for transporting the component from the last manufacturing process to storage ready for assembly. Each group will be given a different component. Aim: The aim of this assignment is to carry out autonomous research into jigs & fixtures and apply the knowledge gained to developing an optimum fixture for a particular component. An important aspect of the assignment is to carry out cost analysis of the designed fixture. Background: 1. You should already have selected your group. 2. Each group will be given a component. The component you have is the finished product – no further processing is required. 3. The component needs to be placed on a fixture, which will take it on a conveyor system from final machining to a storage system. 4. The fixture size cannot exceed 100 ? 100mm. The depth is dependant on the way the component will be ‘held’ in place. 5. There must be only ONE way that the component can be placed on your fixture. That is, the application of PokeYoke – you will investigate this concept yourself. The direction of component location will be given in the lecture. Assignment: 1. Produce a report that clearly outlines the following: i) Your approach to the problem. What mechanism/technique did you use to arrive at the optimum solution of the fixture? What alternative designs did you examine and why were these rejected. You are strongly advised to use the notes on evaluation of designs on my web site. ii) Comprehensive details of the final design of the fixture. This must include the manufacturing drawings, the actual materials that will be used (the prototype is made out of ABS plastic). The full costs of manufacturing a quantity of 100 off. The costing must be comprehensive. You should use the methodology detailed in the book ‘Jigs & Fixtures’ 4th Edition by Edward G Hoffman. Copies of this book are available in the library. You must clearly state the source of any costs that you have used. Keep in mind the tolerances of the fixture, as the component will need to be removed easily. iii) A complete manufacturing process plan. This stage must clearly show the steps to manufacture your fixture from whatever material you have chosen. iv) A 3D drawing of your final design. Include a printout in the report. 2. A Peer Assessment report. This must be fully completed. Simply giving marks against each category without any overall comment for each member in your group will lead to a mark of ZERO for you! I will explain this in more detail in the lecture. 3. Produce a file using AutoCAD/SolideWorks or any other package to enable a prototype to be manufactured. Please ensure that the dimensions are correctly set – e.g. not in meters! The technicians using the School Rapid Prototype facility will manufacture the prototype. The file must be in STL format. This file must be ready by 1.00pm 30th November 2015 and handed to me in my office (P334) on a flash drive. Your file name must be in the following format: GROUP<your group number>.STL If I do not receive a file by this date, you will NOT be allowed to do the presentation and will most likely lead to you failing this assignment. The 10% are for your file being of correct format and the drawing contained therein being of the correct dimensions. 4. The completed prototype will be tested at the presentation to determine if the requirements of Poke Yoke have been met. If it meets the foolproof idea, then you get full marks otherwise zero. 5. Presentation: This will be assessed as follows: a. Presentation skills. b. Technical content. c. Ability to answer questions asked. Keep in mind that the higher the mark, the greater the requirement in terms of high standard of investigation and quality and NOT quantity!
