Introduction: CNC based subtractive manufacturing has been in industry standard by which many of the parts and

products have traditionally been realised. With respect to advanced manufacturing these processes

typically require an appreciation for part digitisation, CAD/CAM and the intrinsic machinability, while

materials are eroded to product the end product. By contrast additive manufacturing has emerged as

a new manufacturing paradigm, with significant potential to supersede traditional manufacturing

processes.

As with advanced subtractive manufacturing, part digitisation and CAD/CAM are critical elements in

the machine interfacing, but with many subtle differences in what can be achieved at the design to

manufacturing interface. More crucially, materials are added in a stepwise fashion, building a part

from the ground up into the end product. Many believe additive manufacturing may someday replace

subtractive manufacturing as part of the new industry 4.0, while other believe there is a place for both,

and indeed each are complementary technologies to one another.

Assessment task:

You will be required to produce a state-of-the-art literature survey on the topic of Additive Manufacturing compared with Subtractive Manufacturing processes. In this report you will examine a very brief historical context of both technologies, before exploring the similarities and differences in each technology. Attention should be paid to the digital interface of each technology, drawing upon the elements discussed in both the lecture and practical sessions. Your report should include but not be limited to discussions of

• The relevance of part digitisation and it implications on the design and evaluation process • Limitations on what can and cannot be realised by design

• Manufacturing similarities and constraints

• Material processing capabilities

• Manufacturing complexity and ease of use

• Variations of technological platforms

• Performance based metrics – Resolution, quality, production time, multiplexing, etc

You will need to refer to peer reviewed literature (e.g. journal papers, textbooks, technical standards) to collate and report most of your information. You are discouraged from using ‘weak’ references such as web forum/discussion groups, and other subjective sources.

Writing the Report:

It is highly recommended when writing the report you apply the same rules and guidelines to structuring, formatting and writing used in Assessment Task 1 for the machinability paper. You are welcome to use the recommended title template below as a guide to structuring your paper.

Your report should be minimum of 2000 words (excluding references). It should not exceed 2500 words. This is an individual submission, this paper must be written in your words. Do not copy and paste large paragraphs from literature straight into your paper, instead you are strongly encourage to paraphrase, i.e. re‐write the text in your own words. You must also clearly check the spelling and grammar of your own work. Any detected written work which has been poorly written, will be given a poor grade.

Any references used should be cited using an approved style and avoiding plagiarism (see link below). This means you are expected to write the assignment in your words, and not use those of the references you find. Students are encouraged to work together, however, ALL work submitted must be written in the individual students own words. Turnitin software will be used on all assignment submissions.
