ASSIGNMENT: Sustainability analysis of a design and sustainable manufacturing routes for critical parts

A customer has offered to your company to undertake the work for producing a device or equipment designed by a design bureau. Your company assigned 3-4 people to analyse the design work and to work out suggestions for sustainable manufacturing of critical parts from the design. Your analysis will be used to assess the complexity of the design, to assess the load of the manufacturing equipment and possible bottle neck operations and finally will allow the top management of the company to offer a quotation to the customer stating how much will the work cost and when the production will be ready. Your work also will provide customer with suggestions and ideas of design improvement, manufacturing constrains and guarantees for the functionality of the designed equipment.

Prepare a formal written report:

The assignment is to develop the technical part of a business case to support the design and manufacture of a specific device or equipment. Prepare a Word document and write formally (i.e. avoid use of "I" or casual terms). Start each of the four parts on a new page (this is to aid the marking process).

Part 1) Introduction

Evaluate the suggested for analysis design. What is it, which are the most common types of such devices or equipment? What are the critical functioning parameters, what is the devise or equipment used for, etc?

Part 2) Design Quality Chains for the critical functional parameters of the suggested design

  1. Create the Quality chains required for the specific assembly which will guarantee the workability of the design; Short Quality chains can be graphically represented on the assembly drawing, but the long Quality chains, where the graphical representation will be difficult, should be described as shown below:

Example:

AΣ - clearance in the gear engagement of ...

A1 - radius of the basic diameter of ...

A2 - run-out of ...

.......

  1. Select a method of ensuring the quality of the functional parameters and calculate the Quality chains using methods of full interchangeability, partial interchangeability, group interchangeability and compensation method. If needed justify the use of the method of compensation and calculate the compensator(s). The aim is to assign the biggest possible tolerances and guaranteeing the workability of the design. This is directly linked to the sustainability of the new product!

Part 3) Detailed design and tolerancing

  1. Sketch the selected (or pointed by the supervisor) parts and dimension them;
  2. Assign tolerances of all dimensions of the selected parts and justify the selection. If needed write additional technical requirements;
  3. According to assigned dimensional tolerances and findings from the Quality chain calculations, assign tolerances of shape and position if and where needed.
