Staffing

Examiner: Canh-Dung Tran

Rationale

The successful practice of the profession of Mechanical Engineering requires a clear understanding of the relationship between engineering and engineering practice. An ability to recognise when a particular theory is applicable and an ability to accommodate the deviations from the theory that occur in the real world is essential. Some knowledge of a wide range of practical techniques, proprietary devices, materials, construction methods etc is also necessary. The engineer must be able to assess a complex situation, identify the critical elements and develop a workable, cost effective solution. All of this requires considerable self-confidence, and the ability to work with and lead teams.

Synopsis

The course comprises two parts - engineering metrology and computer assisted machining. It is the aim of this course to provide students with practical skills associated with each of these areas. Metrology activities include precision measurement of component features, form and geometry utilising specialised measuring instruments and equipment. Subsequent analysis and presentation of measurement data also form part of metrology. Computer assisted machining encompasses NC programming methods, program preparation, program verification and machining utilising computer software and technologies. The activities will be carried out individually and in groups.

This course contains a mandatory residential school for external students and mandatory on-campus laboratories or practical classes for on-campus students.

Objectives

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

  1. conduct and utilise an engineering test in accord with a given general requirement;
  2. operate a range of engineering metrology equipment and analyse the data obtained;
  3. co-operate within a team-work environment;
  4. prepare CNC programs to machine a number of simple engineering components;
  5. participate in the CNC machining process for two simple engineering components.

Notes
  1. The dates and location of the mandatory residential school are available from the Residential School Timetable (http://www.usq.edu.au/handbook/current/resschoolsched.html). On-campus students can follow the Class Timetables (https://www.usq.edu.au/current-students/organise-enrolment/timetables/class) as a guide or enrolled students can refer to their student portal and navigate to Student Centre>Self Service>Timetables>My Weekly Schedule.

Important assessment information

  1. Attendance requirements:
    External students must attend the mandatory residential school and on-campus students must attend the mandatory on-campus laboratories or practical classes. It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.

  2. Requirements for students to complete each assessment item satisfactorily:
    To satisfactorily complete each assessment item students must achieve a mark of 1 out of 1 for that assessment item. If, in the opinion of the examiner, the accuracy of results obtained from the metrology activities is below the standard specified in the assessment scheme then students may be required to resubmit their assessments.

  3. Penalties for late submission of required work:
    Students should refer to the Assessment Procedure http://policy.usq.edu.au/documents.php?id=14749PL (point 4.2.4)

  4. Requirements for student to be awarded a passing grade in the course:
    To be assured of receiving a passing grade students must attend and participate in the mandatory residential school and achieve a mark of 1 out of 1 for each assessment item.

  5. Method used to combine assessment results to attain final grade:
    As P is the only passing grade available for this course, all students who are qualified for a passing grade, under the requirements in 4 above, will be given a grade of P. Other students will be given either a Failing grade or an Incomplete grade.

  6. Examination information:
    There is no examination in this course.

  7. Examination period when Deferred/Supplementary examinations will be held:
    Not applicable.

  8. University Student Policies:
    Students should read the USQ policies: Definitions, Assessment and Student Academic Misconduct to avoid actions which might contravene University policies and practices. These policies can be found at http://policy.usq.edu.au.

Assessment notes

  1. Students must familiarise themselves with the USQ Assessment Procedures (http://policy.usq.edu.au/documents.php?id=14749PL).

  2. Referencing in Assignments must comply with the Harvard (AGPS) referencing system. This system should be used by students to format details of the information sources they have cited in their work. The Harvard (APGS) style to be used is defined by the USQ library’s referencing guide. These policies can be found at http://www.usq.edu.au/library/referencing.

  3. As part of the mandatory residential school, students may be expected to undertake a combination of lectures, tutorials, laboratories, practical classes and assessment as advised by the course examiner.
