Skills covered by this unit are applied individually or in a team environment where comprehensive responsibility for the production of the drawing is exercised, and critical dimensions and associated tolerances are determined where required.

Manual drafting and drawing equipment is used or where a CAD system is used, Unit MEM09009C (Create 2D drawings using computer aided design system) and/or Unit MEM09010C (Create 3D models using computer aided design system) should also be considered.

ELEMENT

PERFORMANCE CRITERIA

1. Prepare mechanical assembly, layout drawings

1.1. All drawings are produced to Australian Standard 1100 or equivalent.

1.2. Dimensions of various components are determined and inserted and appropriate symbols for limits and fits, surface texture and geometric tolerances are included.

Required skills

Look for evidence that confirms skills in:

producing all drawings in accordance with AS1100 or equivalent, see above notes in range statement

representing the function of each component within the assembly/layout in accordance with design specifications/operational requirements

manufacturing, fabricating and assembling all components in accordance with the specifications contained in the drawings

where appropriate, orientating all components correctly to surrounding structures and services

where appropriate, modifying drawings to ensure conformance to specification AS1100 or equivalent, and/or changes to production, assembly and fabrication requirements and/or the availability of standard hardware items etc.

reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents

planning sequencing operations

checking and clarifying task related information

checking for conformance to specifications

undertaking numerical operations, geometry and calculations/formulae within the scope of this unit

Required knowledge

Look for evidence that confirms knowledge of:

function of each component within the assembly/layout

manufacturing, fabrication and assembly procedures to be used in producing the components/assemblies

reason for ensuring that all components are correctly orientated to existing or proposed structures and services

reasons for updating/modifying drawings to incorporate changes to specifications, production, assembly and fabrication methods and availability of standard hardware items, etc.

hazards and control measures associated with performing advanced mechanical detail drafting, including housekeeping

safe work practices and procedures

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 perform advanced mechanical detail drafting. Competency in this unit cannot be claimed until all prerequisites have been satisfied.

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.

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. The assessment environment should not disadvantage the candidate.

This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with performing advanced mechanical detail 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.

Guidance information for assessment

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Australian Standard 1100 or equivalent

Complete familiarity with AS 1100.101 or similar and its application is required in the respective field
