This unit applies to assembly operations that are essentially manual in nature and require the application of accepted engineering principles and practices. Assembly activities typically involve build-to-order work and/or low volume and/or complex assemblies and/or long assembly time frames. This is a production-oriented competency. Work may involve manual adjustments to achieve correct specification.

Where varying levels of measurement competencies are required, refer to Units MEM12023A (Perform engineering measurements).

This unit should not be selected when Unit MEM18055B (Dismantle, replace and assemble engineering components) has also been selected.

PERFORMANCE CRITERIA

1. Read and understand job sheets

1.1. Job sheet or equivalent instructions are interpreted correctly.

1.2. All components/sub-assemblies are checked against job sheet, assembly list or equivalent instructions.

1.3. Fitting requirements and sequential assembly planning are carried out where applicable.

2. Select and use assembly tools and equipment

2.1. Tools, equipment and components/sub-assemblies are selected to meet job requirements.

3. Assemble engineering components

3.1. Defective or faulty components/sub-assemblies are identified and processed according to standard operating procedure.

3.2. Components/sub-assemblies are correctly prepared for assembly.

3.3. Techniques and principles appropriate to the job requirements are applied in assembly activity.

3.4. Records/inputs are accurately maintained or processed.

3.5. Components of assembly are fitted to ensure correct positioning and conformance with specifications.

3.6. Assembly is tested to ensure that components interface/interact according to operational specifications.

4. Adjust mechanical assemblies

4.1. Final adjustments are performed on assembly to ensure alignment with operational specifications.

4.2. Faulty assemblies are identified for rework by operator or, where the fault is outside the scope of the workstation, processed according to standard operating procedure.

4.3. The assembly is correctly marked/tagged/identified.

5. Protect assembly from damage

5.1. Components and/or assembly are handled and stored according to standard operating procedures and in a manner least likely to cause damage.

Required skills

Look for evidence that confirms skills in:

reading and interpreting routine information on written job instructions, specifications and standard operating procedures. This may include drawings

preparing a sequential assembly plan

selecting and sourcing appropriate tools, components and sub-assemblies

using tools appropriately

following job instructions

identifying faulty components

following oral instruction

entering routine and familiar information onto proformas and standard workplace forms

Required knowledge

Look for evidence that confirms knowledge of:

fitting requirements

uses of relevant tools and equipment

sequence in which the tasks are to be performed

sources of the component/sub-assemblies

required action for tests and checks

required action for non-conformance

damage to components and/or assemblies through the use of inappropriate handling and/or unsafe storage procedures

relevant record keeping requirements

use and application of personal protective equipment

safe work practices and procedures

hazards and control measures associated with precision assembly

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 assemble and test complex engineering components and mechanical assemblies. 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 precision assembly 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.
