Design for Additive Manufacturing (DfAM)
Importance of additive Manaufacturing in Improving Production of a Product (In this case, Jet Engine Turbine Blades)
Instructions
Here are the guidelines for your course paper this semester. I want this paper to add value to your career, using additive, and the most important thing to learn is how to adapt design and engineering thinking to take advantage of 3D printing. We refer to this adaptation process as Designing for Additive Manufacturing or DfAM. Therefore the paper topic is DfAM.
Paper Topic: Design for Additive Manufacturing (DfAM)

Background: Additive Manufacturing makes complexity free (sort of), so take advantage of it. Curved surfaces, pockets and undercuts are very expensive to produce in subtractive manufacturing, but relatively “free” in AM. How can you take advantage of “free” complexity in a product that you choose from your local environment? What are the advantages, technical and economic, of choices you would make in redesigning your chosen product.
Select an object or product that interests you, perhaps something from your work, research or a class. Choose something that makes sense to produce using AM compared to other methods of production manufacturing (subtractive or formative). It could be an assembly of more than one component. Discuss why you think this product could be improved using AM, and how. Provide images or drawings of your object(s), with a few representative annotations that show what you think are “critical” dimensions.
Discuss user/customer requirements for the object(s) you chose. What color, surface finish, durability/duty cycle, temperature, chemical resistance, etc. are you envisioning will be required for your object(s)?
***VERY IMPORTANT *** Consider how you would design or redesign this object to take best advantage of AM. Discuss how could and would take advantage of the power of additive manufacturing in this object. Be specific – what features could be made better and how? Which of the requirements you listed above would be better addressed because you have additive?
What would you design differently if you have AM as a tool? How did you think and design differently to take advantage of AM? Be specific.
Which AM process(es) would be better or not for your design/object? Select an additive process for your object. Discuss your thought process – why did you choose this process? How would you create the object using the process you have selected, considering the strengths and limitations of AM in producing your object? What tradeoffs will you have to accommodate because of your selection? What orientation and scale trade-offs do you consider important for the particular AM process you selected and why? What material would you choose and why?
How will you define “quality” for your object? What parameters of quality do you think will matter most for your object? Consider these parameters as quality requirements. How will you validate the quality of your object according to these requirements when its produced?
***VERY IMPORTANT*** – What are the cost trade-offs you will make using AM to produce your object vs. another method of manufacture? What types of post-processing will you have to accomplish to deliver your object in its final form (per requirements above)? What does “complexity is free” mean with respect to your object(s), or doesn’t it?

4 Vertical Alignment Design
A road must be designed to cross some railway tracks. The approaches are both flat, with no horizontal curvature and are at the same level. The vertical alignment comprises a level approach at ground level, a sag curve, a single crest curve over the railway, and a sag curve returning to ground level. The maximum permitted gradient is 6%, and lengths of this gradient may be used between the crest and sag curves if required. The railway tracks are at ground level and are [W] metres wide. The road alignment must be at least [h]metres above ground level over this entire width.

Alternative Dispute Resolution (ADR)
Alternative Dispute Resolution (ADR)
Assignment based around ADR
What is ADR?
- Any method for resolving a disagreement that is an alternative to the courts
- Encouraged by the governments and court inside and outside the UK
- Parties are obliged by UK law to use ADR to avoid ending up in court
- Courts can penalise parties who unnecessarily end up in court when they could have reasonably used ADR.
ADR is growing around the world
- Economic recession and increasing costs of dealing disputes in the courts has seen increasing demands for cheaper and quicker alternatives.
- Governments and judiciaries around the world are actively encouraging use of ADR.
- Tenancy agreements, building contracts and other commercial contracts now routinely include dispute resolution provisions, which enable parties to resolve their disputes privately, and without going to court.
- Industries
Alternative Dispute Resolution= ADR
- Arbitration
- Mediation
- Dispute Boards
- Expert determination
- Ombudsman
- Negotiation is the ODD ONE OUT (tactic where you find 2 parties discuss an answer and to get to a resolution) best cheapest and quickest one to ADR
- Independent Review etc.
Problem with courts:
- -time
- money
- one or both parties still unhappy
- relationship damage
- reputations
ADR is in growing use around the world
- Economic recession and costs of resolving disputes
- Government and judicial encouragement
- Commercial imperative leading to innovation and adoption of new ways
Arbitration, a form of ADR it’s a way to resolve disputes outside the courts. The dispute is decided by an arbitrator who produces a decision called an arbitration award is legally…
- Form of ADR offers an alternative to the courts for resolving disagreements
- Regulated in UK by act of parliament, Arbitration act 1996 opsi.gov.uk – go to legislation UK Acts 1996
- A party cannot take the same disagreement to court once it has been arbitrated
UK Arbitration
- Used to resolve many types of commercial property disputes
(approx., 3000 rent review arbitrators appointed annually by RCIS
- Manage rural property disputes
Disputes under the agriculture holdings act 1986 & agriculture tenancies act 1995
- Provides resolution for construction disputes
Not so frequently used now as 28 day adjudication has been more popular since 1998 in the UK, but remains popular in non-UK jurisdiction E.g. UAE.
International Arbitration
Used internationally
International contracts such as FIDIC (federation of international
New York convention on Arbitration Awards
Local laws and regulations
Arbitrators Role
Act like a judge
Decision maker
Challenge
Powers
Evaluation of opinion
Jurisdiction
Awarding costs
Limits of the dispute
Immunity
Advantages of Arbitration
Faster than litigation in court
A time limit can be placed on the length of the process
Cost – cheaper and more flexible
Informal – more commercial and less formal than court
Confidentially – unlike court rulings, arbitration proceedings and arbitral awards are confidential.
Disadvantages
No appeals, the arbitration decision if final. Even if one party feels that the outcome was unfair, unjust or biased they cannot appeal it
Evidence – rules of evidence may prevent some evidence from being considered by a judge or a jury, but an arbitrator may consider that evidence, So an arbitrators decision…
Expert determination is described as a procedure by which the parties to a dispute appoint an independent and neutral expert to determine the dispute in private. Like arbitration, it allows trade secrets and other sensitive information to be kept out of the public domain. The expert is a person with specialist or technical knowledge relevant to the dispute. Their experience and professional knowledge are expected to help solve the dispute.
Expert determination
Provides cost efficient resolution for dispute and problems, confidential and private.
Controlled by parties so scope of jurisdiction and terms of reference come from contract with parties so is unable to award costs unless the contracts state so.
Knowledge and expertise?
No legal mechanism?
Right or wrong? ( see johns wood )
Mediation – is a dynamic, structured interactive process where an impartial third party assists disputing parties in resolving conflict through the use of specialised communication and negotiation techniques. All participants in mediation are encouraged to actively participate in the process.
Falls into 3 different methods
- Stakeholder consultation
- Facilitated (helps parties to find their own solution but does not impose his own solutions
- Evaluative (mediator offers views on specific issues or overall positions
Why mediate?
- Quick and informal
- Economically viable
- Able to deal with issues which courts cannot
- Fair and transparent
- Able to maintain relationships
- Adaptable
- Able to deal with emotive issues
- Meditation process – typical steps
- Initial contact with the parties
- Private meetings with each party
- Further private meetings
- Joint meeting setting the agenda
- Exploration
- Settlement
- Follow up
What makes mediation successful
- Releases pressure off wired people
- Moves from entrenchments to forward planning
- Mediator acts as catalyst
- Safe forum to explore people’s needs
- Is flexible not rule bound
- Active listening
- Reality checking
- Gets innovative solutions
- Deals with emotive issues
ADR for the future
Early identification
Benefits of ADR
Quicker
Cheaper
Less formal
Private
Conflict avoidance in dispute resolution- involves carefully and properly planning with clarity the strategy for executing a project…
Why conflict avoidance?
Benefits:
- Helps parties to prevent and control disagreements through a bespoke contract
- Flexibility pay as you go
- Promotes ownership of issues in disagreements
- Encourage collaborative working
- Issues reviewed by independent panels of experts who make non-binding recommendations

The Einstein-Podolsky-Rosen Argument in Quantum Theory
Readings: Be sure to read John Norton’s e-book chapter (Lecture 5.2).
You may also wish to have a look at the SEP article by Arthur Fine on The Einstein-Podolsky-Rosen Argument in Quantum Theory or Laszlo Szabo’s The Einstein-Podolsky-Rosen Argument and the Bell Inequalities. (Links all down below!) Background.
It would be hard to evaluate the incompleteness thesis without some discussion of the phenomenon of entanglement, so you should expect to discuss this briefly; however, you will not have enough words available to develop all of quantum mechanics in this essay, so you should try to extract only the bits of quantum mechanics that you need to make your point.
Make sure you are giving a clear reconstruction either of the EPR argument or Einstein’s argument given in his Autobiographical Notes. Finally, articulate which assumption of Einstein’s argument is suspect and why.

THESE ARE ADDITIONAL GENERIC INSTRUCTIONS: PLEASE READ CAREFULLY AND ALWAYS KEEP IN MIND WHEN WRITING YOUR ESSAY.
Writing Philosophy You’ll only really learn to write a good philosophical essay through practice; but again a few hints can be given. Always answer the question you have been asked.
The main structure of your essay should be dictated by the “question” and, where it really is a question, you should come to some explicit answer to it – even if this is mixed or complex.
Suppose, for example, you were set the question ‘Did Hume show that induction is a rationally indefensible process?’ Then the conclusion of your essay might be something like ‘So, did Hume show that induction is a rationally indefensible process?
I have argued that, relative to one conception of rationality, Hume succeeded; but I have also shown that there is an equally plausible conception under which induction can count as rational, despite Hume’s strictures.’ Or suppose that you are asked ‘Is the moral act always the one that produces the greatest total well-being?’ Then the essay might end with ‘I have argued that there are cases where this utilitarian maxim would lead one to act in a way that is clearly immoral intuitively and hence that the maxim is not generally true.’ Or perhaps: ‘I have argued that, although some philosophers have argued that there are cases where acting to promote greatest total well-being would lead one to act immorally, in fact, on analysis, these alleged counter-examples dissolve, leaving the utilitarian maxim unrefuted.’ Target audience. Your target audience should be the ‘educated layman’, that is, someone who is clever, sympathetic, but has not read the particular material that you have been reading and on which your essay is based (or maybe s/he only dimly remembers most of it). Having such a target will force you to try to give a clear account of the material at issue; if instead you plunge into a detailed discussion that presupposes that material, it won’t be clear (not even to yourself) whether you have really understood it. Use your own words. Although we do not usually expect originality (after all, the people you will be reading have been thinking about the issues for years, not weeks), we do expect you NOT to write an essay by simply copying chunks from the reading. To do so without reference amounts to plagiarism; you should always cite the author when you do quote. But you should in any event avoid long quotations. The occasional very sharp quotation is fine, but in general you should use your own words even when you are straightforwardly describing someone else’s position.
One way to ensure you do this is to put the books aside when you are writing (consulting them again only when you get stuck). You obviously haven’t understood someone’s position if you can’t re-express it independently. Style. Do not aim to impress with your erudition and capacity to write long intricate sentences involving long words. Try to express your views (and those of the authors you report) as simply and concisely as possible. A good test is to read your essay out loud: if it sounds awkward, re-express it more simply. 8 Scholarly apparatus. When you paraphrase or quote a piece, give a full reference, including a page number (or, in some cases, such as classic texts, a section, paragraph and line number), in any of the standard formats (see any contemporary article or book published with a leading press for an acceptable way of citing). In summary, each essay is evaluated on the basis of the following. Expression and style Structure and organisation Understanding and use of literature Quality of analysis and evaluation Quality of argument Independence and originality We would further add that a good essay always begins by stating a clear thesis in the introduction, and its aim is to formulate a valid, compelling argument over the course of the essay. ADDITIONAL PHILOSOPHY WRITING GUIDE: https://personal.lse.ac.uk/ROBERT49/teaching/Guide.pdf PLEASE GET IN TOUCH IF THERE ARE ANY ISSUES AND WE CAN SORT THEM OUT TOGETHER. BEST OF LUCK AND I REALLY DO EXPECT THE HIGHEST POSSIBLE QUALITY WITH NO PLAGIARISM AT ALL.
