MECHENG 236 : Design and Manufacture 2

Engineering

2025 Semester Two (1255) (15 POINTS)

Course Prescription

Applying the engineering design process to mechanical parts and assemblies, with consideration of risk management and manufacturing impacts. Design for common production processes and fabrication methods. Design of machine elements including hydraulic and pneumatic systems and components. Documenting and communicating detailed design process and outputs.

Course Overview

 This course complements the conceptual design and prototyping introduced in MECHENG 235, shifting the focus to detailed design and manufacture. Topics covered include:
  • Introduction to common plastic and metal manufacturing and fabrication processes
  • Design of injection moulded parts and parts made by material removal processes
  • Machine elements and their use in design, including bearings, shafts and keys, gears, brakes/clutches and fluid power systems
  • Approaches to robust CAD modelling of parts and assemblies
  • Detailed mechanical design documentation, specifications, and tolerances (limits and fits and GD&T)
  • Risk management, safety, reliability and quality
  • Project management, documentation management, ethics, team conflict management
Teaching is delivered in interactive lectures, tutorials, and labs, that support progress towards two key projects and a final exam.

Exam
  • Students must sit the exam to pass the course. Otherwise, a DNS (did not sit) fail grade will be returned.
  • A score of 40 % in the exam must be achieved to pass the course. Otherwise, a maximum grade of D+ will be returned.
  • A passing mark is 50% or higher for the combined course assessments, according to University policy.
  • Late submission penalties will be applied as stated on Canvas.

Workload Expectations

This course is a standard 15 point course and students are expected to spend 10 hours per week involved in each 15 point course that they are enrolled in.

For each week in this course, you can expect 3 hours of lectures, 1 hour of tutorial, 1 hour of reading and going through the lecture content, and 5 hours of work on the laboratories, quizzes, projects and exam preparation.

Delivery Mode

Attendance is required at scheduled activities including laboratories and potentially design project presentations, to receive credit for those components of the course.

The Examination will be in-person, paper-based, invigilated, closed book and restricted calculators.

Lectures will be available as recordings. Other learning activities including tutorials and labs will not be available as recordings. The activities for the course are scheduled as a standard weekly timetable.

Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

Health & Safety

Students must ensure they are familiar with their Health and Safety responsibilities, as described in the university's Health and Safety policy. Students will be given a Health and Safety induction before the laboratory sessions commence.

Student Feedback

At the end of every semester students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback and respond with summaries and actions.

Your feedback helps teachers to improve the course and its delivery for future students.

Class Representatives in each class can take feedback to the department and faculty staff-student consultative committees.

In 2025 this course will be refreshed and include new teaching and assessment material. Some key changes addressing student feedback from recent years will be: 
  • Feedback: Lack of relevance between lecture content and assessments. Response:  Lectures and tutorial activities will be developed to directly link to assessment and learning outcomes.
  • Feedback: Semester long, open ended design project with confusing instructions was painful. Response: two smaller projects will be developed, with clear expectations. 

Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework, tests and examinations as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. A student's assessed work may be reviewed against electronic source material using computerised detection mechanisms. Upon reasonable request, students may be required to provide an electronic version of their work for computerised review.

Class Representatives

Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.

Inclusive Learning

All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.

Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website http://disability.auckland.ac.nz

Special Circumstances

If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.

If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.

This should be done as soon as possible and no later than seven days after the affected test or exam date.

Learning Continuity

In the event of an unexpected disruption we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and your assessment is fair, and not compromised. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator, and if disruption occurs you should refer to the University Website for information about how to proceed.

Student Charter and Responsibilities

The Student Charter assumes and acknowledges that students are active participants in the learning process and that they have responsibilities to the institution and the international community of scholars. The University expects that students will act at all times in a way that demonstrates respect for the rights of other students and staff so that the learning environment is both safe and productive.
