Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

MEM30003A - Produce detailed engineering drawings

What evidence can you provide to prove your understanding of each of the following citeria?

Determine drawing requirements

  1. Drawing requirements are checked and interpreted from work order or similar.
  2. Required information is sourced from workshop manuals, customer specifications, product suppliers, designers or similar.
  3. Scope of drawing including layout, additional required information and resources is planned.

Produce detail drawings in third angle projection, including auxiliary views, sections and assemblies

  1. Drawing details including assembly and components are completed as per AS 1100 or similar.
  2. Dimensions of various components are determined and inserted where required.
  3. Appropriate symbols for limits and fits, surface texture and geometric tolerances are included.
  4. Simple components or layouts are drawn in third angle projection.
  5. An auxiliary view is drawn of a component, given two views.
  6. Correct convention for parts is shown.

Instructions to Assessors

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 produce detailed engineering drawings. 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. Where assessment occurs off the job, i.e. the candidate is not in productive work, an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered 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 producing detailed engineering drawings, 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

Required Skills and Knowledge

Required skills

Look for evidence that confirms skills in:

drawing

documenting

applying principles of geometric tolerances

identifying functional surfaces and datums on assembly drawings

producing detail drawings of machine components and dimension from datums

Required knowledge

Look for evidence that confirms knowledge of:

projection

auxiliary views, special attention

detail drawing methods

standard engineering drawing symbols, references and terminology

projection lines

arrangements

general tolerancing

limits and fits

shaft and hole basis

extremes of fit

surface texture

selection of standard roughness values for given processes

application of surface finish symbols to drawings

selection and application of equivalent surface roughness numbers

geometric tolerancing

simple geometry tolerancing (no datum references, flatness, roundness etc.)

geometry tolerance with datum reference (e.g. parallel squareness)

Range Statement

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.

Geometric tolerances

Simple geometry tolerancing (no datum references, flatness, roundness etc.)

Geometry tolerance with datum reference (e.g. parallel squareness)

Simple components or layouts

May include fabricated components, machined components, cast and forged components, structural details, electrical electronic components, fluid power components

Parts

Mechanical components such as fasteners, bearings, seals, gears, keys, splines etc.

Electrical components such as cables, connectors, terminations etc.

Fluid power components such as actuators, valves, hoses, connectors, relays etc.
