Assignment 1 General Instruction


You are a recently integrated manufacturing engineer at DigiMech Manufacturing, a Smart Manufacturing enterprise, which is expanding their business to incorporate multiple machining / manufacturing processes. Due to this, the manufacturing engineers have been divided in two teams, each addressing the planning and development of a product database and its machining processes involved for manufacturing it from a blank piece to the final part. If the last digit of your ID is even, you are part of the turning team; if the last digit of your ID is odd, you are assigned to the milling team. To be able to carry out this task, you must, first, convert the 2D drawing into a 3D model/part. Then, you will plan, elaborate and carry out the required machining processes on the 3D model/part. You are required to carry out the 3D modelling to the required BSI standard using PTC Creo. You are also required to define the conditions, resources and specifications for each of the machining processes deployed in the manufacturing of the part.


Figures 1 and 2 depict the approximate shape of parts that are produced as part of the company portfolio. The operations required have been defined by contractor CAD/CAM engineers of client companies. Irrespective of the part (and, therefore, the team you are assigned to), the operations involve a volume rough machining, drilling, engraving and a finish machining.


You are asked to represent the listed machining processes on your created 3D model/part, which is made of Inconel 718 nickel superalloy:


  • Face milling operation – the blank piece has 22.225 mm, or 7/8 inches, height (team milling only)
  • Volume roughing
  • Drilling of the holes/slots in the specified dimensions
  • Grooving (team turning only)
  • Engraving using your first name – or surname – and your student ID number as the information to be engraved on the created 3D model/part.
  • Finishing (profiling) operation

For each machining operation, you are required to specify:

  • Cutting parameters (feed – f or feed per tooth/insert – fz , depth of cut – ap , working engagement – ae , cutting speed – vc)
  • Cutting conditions (use of cutting fluid – specification and justification, tool lifetime, number of tools for completing the operation, total operation time – for each machining operation; total machining cycle time, total production cost per machined part)
  • Tool descriptive parameters (tool diameter, cutting edge angle, number of inserts, insert code)
  • Tool code (from a  tool supplier’s catalogue)



Figure 1: Part template for the turning team, with the dimensions based on the ID number.













Figure 2: Part template for the milling team, with the dimensions to be based on the ID number.


Very important guidelines that you must remember and adhere to:

  • You have to map your ID digits to either Fig. 1 or Fig. 2.
  • If working with Fig. 1, the groove width is the same as its diameter. If working with Fig. 2, your extrusion distance/depth for the 3D model/part must be 19.05 mm (3/4 in).
  • A zero digit in the student ID number should be replaced by 10 (being, therefore, the highest digit)
  • For Fig. 2, choose a magnification factor to multiply your digits, in order to keep the approximate shape of the part (and avoid distortion).
  • Figure 1 sections are symmetric.
  • For any of the figures, if one dimension yields an inconvenient geometry, feel free to adopt a modification factor (either for amplifying it or decreasing it). In doing so, ensure the steps are appropriately described in your report.
  • A batch of 500 units of the part you are designing is required.
  • Both parts feature a counter bore hole with the dimensions presented in Figure 3. The placement of the hole is of your choice.
  • As an engineer, you will have to define/research a few parameters for providing some of the estimates asked (e.g. CNC mill cost, total working hours per year, average hourly rate of a machinist, etc.).
  • You must provide a G-code for the entire manufacturing sequence of operations.
  • The word count for the report must not exceed 1500 words. Excluded in this word count are: Title page, List of Figures, Tables, References and Appendix sections.



Figure 3: Counter bore dimensions.


You are required to create a project report on the above contents. You must demonstrate your proposed machining operations by creating a recorded video, expected to last no more than 5 minutes. You are suggested to use one of the following tools:

  • Screencast-O-Matic
  • Sway
  • Power Point
  • Adobe Spark
  • Prezi
  • Microsoft stream
  • Tiny take
  • Nchsoftware

to illustrate, in brief steps, the digital manufacturing processes adopted in your assignment.

Submission Guidelines

There should be a title page which clearly identifies the following:

* Name and code of the module

* Title of the Assessment

* Assessment number  

* Word count

The word count identified includes quotations and citations. However, it does exclude the list of references and/or the bibliography and, unless specifically stated, encompasses a discrepancy of + or – 10%.

Late Submission

If you are not able to complete your coursework on time due to extenuating circumstances*, the ONLY way to receive an extension (up to 5 working days) or a deferral (anything longer than 5 working days) is to contact

Extenuating circumstances are defined by CU as ‘genuine circumstances beyond your control or ability to foresee, and which seriously impair your assessed work’. Please note that you will need to provide third party evidence to support your reasoning for requiring an extension or deferral. Your course tutor is NOT able to approve an extension or a deferral. If you have not completed the official forms and had your request approved, your work will count as not submitted and receive a zero mark.


Guidance Notes and Considerations



Access, Foundation, Year 1 and Year 2:


You should use APA 7th edition style of referencing.

Referencing guidance can be accessed on the Library’s LibGuides pages.


Use of Sources and Information:

You can access high quality, authoritative information via the library. Use LibGuides to access Locate, BibliU and research guidance.

Academic Writing Resources

There are a variety of academic writing resources available which can be accessed via LibGuides. These writing guides can help with different types of assessment as well as important writing skills needed for university.

Glossary of Assessment Terms for Assessment Writing – this is an a-z that covers the majority of terms used in assessment briefs, learning outcomes and feedback throughout the CU Group. If you would like any further support with your assessment, you can contact your Academic Writing Developer or visit the Academic Writing LibGuides page.

If you would like to book an Academic Writing appointment for support with your assessment, you can contact your Writing Developers:

Academic Integrity Guidance

The best way to avoid academic misconduct is to follow appropriate academic and referencing conventions. Further guidance on academic integrity and conduct can be found using LibGuides.

Collusion between students (where sections of your work are similar to the work submitted by other students in this or previous module cohorts) is taken extremely seriously and will be reported to the Academic Conduct Panel. This applies to all coursework and exam answers. If you would like more guidance on understanding collusion, you can find it on LibGuides.

If an assessment suspected of involving a breach of academic integrity is found to display a marked difference in writing style, knowledge and skill level from that demonstrated elsewhere on the course, you may be required to undertake a Viva Voce in order to prove the coursework assessment is entirely your own work.


Proofreading of assessments by CU approved proofreaders is permitted. There is a list of approved proof readers along with guidelines for use. However, please remember that proofreading is a lengthy and detailed process for which there is a cost. If you decide to use a proofreader, please take this into account and contact them at least 10 days in advance of your assessment deadline. 

You must not submit work for an assessment that you have already submitted (partially or in full), either for your current course or for another qualification of this university, unless this is specifically provided for in your assessment brief or specific course or module information.

It is important to realise that as a student you should not submit all or part of an assessment for which you have already received academic credit, to be used for an assessment in a different module. Reusing your own work in this way is called self-plagiarism. Where you wish to refer to some of your own work you must reference it in the same way that you reference work by other people.
