Unit of competency details

Unit descriptor 

This unit defines the competencies required to represent the design of mechanical and manufacturing engineering products, processes, systems or services using appropriate graphical techniques, specifications and documentation. Work would typically be carried out as part of a design team.

Application of the unit 

Competency in this unit includes contribution to the full design process by the creation of documentation, graphics and specifications representing products, processes, systems or services in support of the planning and design processes within mechanical and manufacturing engineering. Graphics may be produced using manual or CAD software and techniques.

This unit only has application in qualifications that are not points based.

Assessment of performance is to be consistent with the evidence guide.

ELEMENT 

PERFORMANCE CRITERIA 

1. Clarify product, process, system or service design requirements

1.1. The design specification of the required product, process, system or service is discussed and clarified with the client and design team.

2. Apply graphical techniques to produce the initial product, process, system or service design representation

2.1. The initial graphical representation satisfies the design specification, manufacturing and operational requirements, safety and related standards.

2.2. Engineering calculations were made, engineering references, standards and codes used appropriately to determine dimensions, limits and fits, surface textures, datum references and geometric tolerances.

2.3. Initial design representation identifies materials, manufacturing methods and processes.

2.4. Initial production graphics, specifications and operating and maintenance instructions/manuals are prepared in accordance with the agreed design concept and organisational requirements using chosen graphical techniques.

3. Validate the product, process, system or service representation

3.1. The suitability of the product, process, system or service design graphical representation is confirmed with the client, other team members and organisational requirements.

4. Develop, validate, implement and file design graphics and specifications and procedural documentation

4.1. Design graphics, specifications and instructions for the product, process, system or service are prepared in accordance with the agreed design concept and organisational requirements and incorporate feedback on initial design graphics and documents.

4.2. The production graphics, specifications and instructions for the product, process, system or service are checked with the client, design team and other affected persons for suitability prior to implementation.

4.3. Implementation installation and commissioning feedback is responded to in accordance with organisational requirements.

4.4. The validated production graphics, specifications and instructions for the product process, system or service are maintained throughout the implementation, installation and commissioning processes, processed and filed in accordance with organisational requirements.

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

Look for evidence that confirms skills in:

• appropriate communication skills for contacting and confirming specifications with the client
• discussing the alternative options and their relative strengths and weaknesses with the client and selecting the most acceptable option chosen
• applying graphical techniques correctly
• addressing design specification, manufacturing and operational requirements, safety and related standards appropriately in the initial graphical representations
• presenting the graphical representations the dimensions, limits and fits, tolerances and surface textures, datum references and geometry tolerances as determined by design calculations and in accordance with engineering references, standards and codes
• producing initial graphical representation and documentation materials, manufacturing methods and processes and design functional specification sufficient for client, design team and interested party consultation and validation
• producing initial graphical representation/s to organisational requirements using suitable graphical techniques
• producing initial production graphics, technical specifications and operational and maintenance instructions/manuals in accordance with work site procedures and client's needs
• using appropriate communication skills in confirming that the design graphical representation meets the needs of the client and the expectations of other team members and interested parties
• completing organisational procedures and "sign off" documentation
• preparing production graphics, specifications and instructions in accordance with the agreed design concept and organisational requirements and incorporating feedback on initial design graphics
• contacting the client, design team and other affected persons and the production graphics, technical specifications and verifying operational and maintenance instructions/manuals prior to implementation
• incorporating feedback from the implementation, installation and commissioning phases into final graphics, specifications
• processing, filing and saving all graphics, specifications, instructions and related documentation in correct format and location in accordance with work site procedures

Required knowledge 

Look for evidence that confirms knowledge of:

• the procedures for collaborating with the client and other staff in the selection of the preferred option
• significance of graphical representations of designs in terms of procedural requirements, design objectives and client or contractual requirements
• relevant manufacturing and operational requirements, safety and related standards
• the functional operation of the component/assembly to be drawn
• surfaces that are to be in contact or separated

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 represent the design of mechanical and manufacturing engineering products, processes, systems or services for a range of general engineering applications. 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 represent the design of mechanical and manufacturing engineering products, processes, systems or services 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.
