Modification History
Release 1 - New unit of competency
Unit Descriptor
This unit of competency covers the skills and knowledge required to produce detailed engineering drawings containing bearings and mechanical seals, engineering keys and keyways, holes and shafts to provide specific clearances by applying general tolerances, and confirming the geometric shape of components by applying geometric tolerances.
Application of the Unit
This unit is suitable for those working within a drafting work environment and can be applied across all engineering disciplines. Drawings may be carried out with or without the use of computer-aided design (CAD) systems and are completed to Australian Standard (AS) 1100.1–1992 Technical drawing – General principles.
If CAD systems are to be used, the unit MEM30031A Operate computer-aided design (CAD) system to produce basic drawing elements, should also be selected.
Drawings are completed under supervision.
Licensing/Regulatory Information
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Evidence Guide
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package. |
|
Overview of assessment |
A person who demonstrates competency in this unit must be able to interpret and apply drawing specifications and industry standards in the production of mechanical drawings which detail bearings seals and other componentry. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts. Specifically the candidate must be able to:
|
Context of and specific resources for assessment |
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability. Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities. This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with drafting or other units requiring the exercise of the skills and knowledge covered by this unit. |
Method of assessment |
Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways, including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. |
