Course Description

This unit of competency sets out the knowledge and skills required to apply basic principles of metrology to the manufacture of products during and after fabrication.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

The unit applies to manufacturing processes in engineering. The metrology task is carried out by measuring part quality characteristics and comparing them with design specifications. It includes the control of tolerances in mechanical parts, methods of measurement, selection of  measurement instrument and the application of statistics to the measurement process.

This unit of competency is intended for courses at diploma or higher levels.

Overview of Assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit:

  • demonstrate essential knowledge and skills as described in this unit;
  • demonstrate a representative body of performance criteria within a timeframe typically expected of the discipline, work function and industrial environment;
  • demonstrate a range of metrology processes on more than one occasion and in different contexts.
This includes a final report that describes the processes used in detail, the assumptions made, control and environmental measures taken,
the assessment of results obtained, all necessary statistical and error calculations, and recommendations with respect to inspected manufacturing process.

Assessment may incorporate a variety of methods including written/oral activities and demonstration of practical skills to the relevant industry standards. Participants are advised that they are likely to be asked to personally demonstrate their assessment acitvities to their teacher/assessor. Feedback will be provided throughout this course. Evidence of the student’s competance can be gathered through a variety of methods, including:

  • observation of processes and procedures
  • oral and/or written questioning on required knowledge and skills
  • testomony from supervisors, clients and/or other appropriate personnel
  • inspection of the final product or outcome
  • a portfolio of documentary evidence
Graded assessment out of 100 marks will be based on practical activities, asssignments, reports, tests and/or written/oral examinations

Candidates must gain a pass in all the components of the assessment/s in order to pass this competency.


Assessment Tasks

Assessment 1 – Laboratory Practical’s x 4

To be competent in this unit the candidate must be able to set up a metrology process, apply a metrology process and evaluate a metrology process for quality control.

The practical’s involve analysis and implementation of the elements in this competency. You will be setting up various gauges, supports and fixtures. You will then take precision measurements using appropriate measuring instruments and taking readings. Then you will calculate and interpret the data to make a determination if the item being tested meets specifications. You will then be required to present these results in a report.

These practical’s will have a combined weighting of 40% of the final overall assessment mark.


Assessment 2 – Final Test (Closed Book)

This assessment will focus on your ability to plan and set up a metrology process, apply a metrology process and evaluate a metrology process for quality control. It will require you utilise statistics as applied to measurement and inspection. You will be required to identify appropriate gauges, measuring tools and fixtures to demonstrate this competency’s elements.

The test consists of multi-choice and short answer questions.

This test will have a weighting of 60% of the final overall assessment mark.
