Part A: Manufacturing Simulation Using WITNESS Software

THE BRIEF/INSTRUCTIONS

This is an open-ended assignment. Open-ended tasks have more than one right answer, solution or outcome and can be completed in more than one way.

The aim of the assignment is to use WITNESS Simulation Software to simulate and optimise the manufacturing process of an engineering product or component of your choice. A written technical report will show the creation of the simulation taken by you prior to starting the simulation. The report will contain a proliferation of illustrations/screenshots of elements of your simulation.

The assignment should produce enough evidence for the fulfilment of the following module learning outcomes: Describe and illustrate the scope, context, and significance of manufacturing. Explain, justify, and apply specific manufacturing techniques. Demonstrate knowledge and understanding of the factors internal to the manufacturing systems that affect behaviour and robustness.

Your initial priority should be to create a simple simulation that gives credible results; to gain higher grades look to add elements to the simulation to expand, further refine the model and interpret the results to optimise the processes. Explain and justify your assumptions and decisions and consider how the simulation could be refined once a basic simulation is working.

Table below shows the various processes involved in the main assembly section of a car manufacturing and the cycle time of each work elements.

Tasks

Read the basic WITNESS Training Reference Manual which is has been designed for people who are new to WITNESS. No prior knowledge of simulation is necessary. Familiarity with computing is not necessary but will be advantageous.
Read “Building Your First WITNESS Model” in page 28 of the training manual. This a tutorial showing step by step procedure of how to build the model using WITNESS.
Using Lanner Witness software create a simulation model to show the flow of work through the different manufacturing activities shown in the block diagram.
Identify bottlenecks in the assembly phase so that the process could be streamlined and run more efficiently. Propose ways to eliminate or minimise the bottleneck. Include buffer and conveyor belts wherever possible.
Look to add more elements to the simulation to expand, refine and optimise it. This could include (but is not limited to) things such as adding labour resources to activities to determine minimum staffing levels to achieve maximum capacity or adding Inspection/Quality Control into the process. Highlight potential bottlenecks in the process and seek to improve capacity and efficiency in the process
Conduct more experiments by running several trials. Repeated trials are where you measure the same thing multiple times to make your data more reliable. This is necessary because in the real world, data tends to vary, and nothing is perfect. The more trials you take, the closer your average will get to the true value.
Discuss the findings from your simulations in a report (not more than 1500 words) with respect to your original target goals.
To achieve high grade, use various function in Witness enhance the model. For example, you could use a function to detect the number of parts currently on a conveyor. Timeseries allow you to present simulation results on the screen in the form of a graph which plots values taken from the simulation against. Pie charts allow you to present simulation results on the screen in the standard pie chart format.
Illustrate your report with screenshots of ways in which your simulation functions. Comment on your results and justify your decisions for improvements.

All submitted materials will be evaluated against the following marking scheme (50% of the module marks).

Build the model (50 marks)
Conduct experiments (20 marks)
Analyse and discuss the results (20 marks)
Recommendation (5 marks)
Report quality (5 marks)

SUBMISSION DETAILS

An individual report in MS Word should be submitted using Turnitin within the module’s Moodle space under the Assignments Section. The WITNESS file of your finalised improved model is also to be submitted to a separate link found on Moodle. The word count for the report is 1500 words (+/- 200 words).

PART B : Design A Product for Computer-Integrated Manufacturing

THE BRIEF/INSTRUCTIONS

The main aim of this assignment is to give you experience with design and manufacturing using computer integrated manufacturing techniques. The goal of this task is to study the background in Computer Integrated Manufacturing (3D Printing and Laser Cutter) and to design and machine a mechanical part.

Studying the process involved in taking a part from design through manufacturing students will understand the power and importance of Computer-Aided Machining in a modern manufacturing context.

Students are required to develop a MECHANICAL PUZZLE BOX that can be manufactured in the Digital Fabrication laboratory (dFUEL) using existing facilities.

Manufacturability and assimilability considerations are of paramount importance at this stage due to the nature of the hardware being used, and the sharing of the hardware with other student working on different products.

You will be allocated one of the following projects/Manufacturing techniques to work on design a product as follows:

Technique

Product

Product Size

File

format

Fabrication

Laser

cutter

Hinged

box

Less than 200 mm

.dxf file

Students to book and use the lasers

printing

Gears (2

or more)

To be decided by the student.

.stl file

Students to book and use 3D printing

MARKING (50% of the module final mark)

The work of each student is documented in detail in a final report (1500 word). This report should include:

I. Introduction [15 Marks]

• Brief reasoning behind your chosen design, noting any special features.

• Brief literature review on the manufacturing technique.

II. Complete documentation of Design and manufacturing [30 Marks]

• A brief description of procedures, and accurate and complete documentation of work done on CAD module. [15Marks]

• A brief description of procedures, and accurate and complete documentation of work done on manufacturing. [15 Marks]

III. Discussion: [10 Marks]

IV. Conclusion: [10 Marks]

V. References: [10 Marks]

Physical model quality: [15 Marks]

Report quality: [10 Marks]
