4) 643248-CAD

Assignment Description

To narrow down the gap between fundamental theories and practical applications of Finite
Element Method (FEM) and Finite Element Analysis (FEA) on Computer Aided
Engineering through synergistically and systematically applying what we have learning and
are going to learn in this unit 301022 Advanced Computer Aided Engineering to design a
typical mechanical device – a shredder to perform a design practice and finish design loops
in the assessment task – CAE Design Project.

For the design project, we assume the SCEM 3-D Printing Lab – MakerSpace need a
shredder, which is planned to develop a green 3-D printing closed-loop system for recycling
polymer and metal materials, i.e., Waste Plastics Filament Extrusion, and reusing them in a
filament extruder as depicted in Figure 2. In the proposed green 3-D printing closed-loop
system, the shredder needs to be designed to shred, crush, and grind the thermoplastic
wastes into small pieces that can fit into the extruder. The size of the small pieces is usually
5 mm  5 mm, which allow the auger or drill to transport them to the heat chamber of the
extruder. Dimension consistency of the recycled and shredded plastic pieces helps avoid
diameter variations on final product – the extruded filament.


5) 513481-Mine Pumping

Assignment Description

You are a mine planning engineer at a medium sized operation producing 1.5 mtpa
of coper ore at 3% Cu. The mine was originally designed using a bench height of
15m. Footwall benches were 15 m wide to give a slope angle of 45°, but on the
hanging wall side alternate benches are only 10m wide to produce an angle of about
50°.
You are required to design a drainage and pumping system to deal with the mine
water for the next 10-15 years based on the data in the following sections. As the
mine grade is low and power costs are high every effort should be made to minimise
the operating costs of the pumping system. Describe your proposed drainage and
pumping system with the aid of diagrams where required and explain the general
philosophy behind the system. Detail and assumptions made and make comments
and conclusions as required.
Data
Mine water
Ground water: currently averages 1,000,000 litres/day and is expected to increase
at a rate of 5% per year as the mine deepens.
Mine water: averages 50,000 l/day with small variations in use on an hour by hour
basis.
Water Quality: Run of mine water is expected to be slightly acidic due to the
formation of sulphuric acid from sulphides within the rock
Rock properties: SG of 2.9 for all rocks. Hanging wall and ore have moderate
strength, footwall is very strong.

7) 664224-Design Analysis

Assignment Description

You are required to carry out a finite element analysis of the load cell shown in the diagram below. The object of the analysis, within the context of the course work exercise, is only to determine the relationship between the load applied and the level of strain measured by the strain gauge.

The robustness analysis, within the context of the assessment, is only to be conducted with the consideration of material elasticity, the thickness of the load cell, and the location of the strain gauge (A, refer to Figure 1).

 

YOU SHOULD NOT ATTEMPT TO FIND THE STRESS AROUND THE THREADED HOLE – THE STRESS RAISERS IN THIS REGION CAN BE IGNORED.

The load cell has a simple construction with a uniform thickness throughout. The load is applied via rods screwed in the threaded holes at either end (the load can be either tensile or compressive). The material properties are given below while the individual dimensions should be taken from the Table in the associated file.

Young’s modulus = 210 GN/m2

Poisson’s ratio = 0.28

8) 715161-Master Project 2

Assignment Description

During the manufacturing of hexahedral ABS components of plastics through the use of FDM based
printer of 3D, unwanted errors of shape happen in the product because of shrinkage of heat. In this
paper we observe experimentally the effect of bed heat level alterations on errors of shape which are
deformed of specimen that is hexahedral of 100x50x50mm3which are created through the use of 3D
printer. In the process of printing, the temperature of the head nozzle was put at 240˚C and the speed of
the head was put at 50mm/s. The chamber was closed through the use of a PC-plate. The process of 3Dprinting was performed at 4 distinct temperatures i.e. 50˚C,70˚C,90˚C, and110˚C. After the natural
cooling of the specimen produced, their deformed shape errors were then measured. The consequence
was that the greater the heat level of the bed, the lower the specimen’s deformed errors of shape. IT
should however be noted that in case the temperature of the bed exceeded 120˚C, there was poor
laminating adhesion. That happened due to the material stage alteration and has the capability of
making 3D printing work very difficult as a result. This study’s outcomes can be very reliable in assisting
to set optimum bed temperature situation when using the FDM additive technique during the process of
manufacturing.


9) 675359-solid Modeling

Assignment Description

You are required to use CAD/CAM software (hyperMILL) to generate tool paths for the machining of an aluminium (6061) mould for the manufacture of a composite shell for a remote control car. The design of the mould for the RC car is up to you but you must keep in mind design for manufacture issues relevant to this manufacturing method. The complexity of the shell will have no influence on the mark of the assignment, so keep it simple.

Once you have created the mould design you are to select the roughing and finishing cutting tools (material, length, shape, diameter etc) for machining the mould from the stock material. You may choose to use the same tools for the roughing and finishing stages. You will also need to select the correct speeds and feeds to suit the tool and work piece material using speeds and feeds charts. The following links will prove useful:

http://www.sgs-tool.de/PDF-speedfeeds/SGS-Speeds-Feeds-GP-metric.pdf

Once you have decided on your tooling, speeds and feeds use the SOLIDWORKS hyperMILL add in to generate the tool paths for the roughing and finishing passes. I recommend using ‘Arbitrary Stock Roughing’ and ‘3D Complete Finishing’, for the roughing and finishing jobs as a starting point.

13) 768117-OPERATIONS MANAGEMENT

Assignment Description

You are to make operational assumptions for your simulation to simplify its construction.
Your 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 and refine it. This will involve making
your own assumptions, you may work in groups initially to discuss and decide what
assumptions to start with, and you can also implement your own if you wish. Explain and
justify your decisions and consider how the simulation could be refined once a basic
simulation is working.
Sample initial assumptions: (you do not need to use these and can create your own
assumptions). All staff have the same skill level and can be assigned to any of the activities.
Initially assume all raw materials arrive on time, cut to length and are always in stock. Assume
each machine can operate 8 hours a day 5 days a week. Bought-in items such as springs and
nuts & bolts arrive on time and are always in stock. Assume all queues are infinite.

The deliverable for this assessment item will be a report (1500 words) which covers the design of the device.
This report should also cover all of the dynamics and demonstrate that the device meets the design criteria (manufacturable (at Deakin), testable, rotating part and have at least 1 component that has subsequent
periodic motion). Additionally, the report will detail how the device would be manufactured, including the
manufacturing costs.
