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.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

It is essential that the process and equipment be understood and that the importance of critical material properties, settings and readings is known. Competence must be demonstrated in the ability to recognise and analyse potential situations requiring action and then in implementing appropriate corrective action.

Consistent performance should be demonstrated. In particular look to see that:

marks and cut outs are correct for shape

directionality is observed

other sheet properties are observed, as relevant.

Competence must be demonstrated in the operation of all ancillary equipment to the level required for this unit of competency.

Context of and specific resources for assessment

Assessment will require the marking and cutting out of a range of suitable sheets used in reinforced composite fabrication.

Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.

Method of assessment

A single assessment event is not appropriate. On-the-job assessment should be included as part of the assessment process wherever possible. Where assessment occurs off the job, judgement must consider evidence of the candidate's performance in a productive work environment that includes a sufficient range of appropriate tasks and materials to cover the scope of application for this unit.

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

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

Required skills

Required skills include:

interpreting drawings and procedures

using hand tools and power tools

operating computer numeric controlled (CNC) machines

measuring and marking out

communicating with appropriate people

performing basic computations

Required knowledge

Required knowledge includes:

orientation of plies/reinforcing

direction of fibres (e.g. unidirectional, quad directional and on bias)

weaves (e.g. plain, twill and satin)

use for curves and compound curves

creating patterns for a lay flat

3-D development of shapes

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.

Procedures

Procedures may be written, verbal, computer-based or in some other form, and may include:

all work instructions

standard operating procedures

formulas/recipes

batch sheets

temporary instructions

any similar instructions provided for the smooth running of the plant

good operating practice as may be defined by industry codes of practice (e.g. Responsible Care) and government regulations

Sheets

Sheets include:

reinforcing:

woven

non-woven

pre-preg

cores

timber, such as MDF and plywood

filler material

Requirements of final product

Requirements of final product may be determined from various sources, including:

drawings

product specifications

customer requests

descriptions of required use of product

Requirements of sheet material

Requirements of sheet material include:

strength

flexibility/rigidity

thickness

density

directionality

drape

operating temperature

Lay flats

Lay flats (templates) are the geometric development of 3-D shape into a 2-D template which will allow the 3-D shape into be fabricated from a 2-D sheet. The lay flat may not take into account the required directionality.

Lay flats may be:

physical (e.g. board and sheet metal)

virtual (e.g. coordinates and laser beam)

Regular rectilinear shapes

Regular rectilinear shapes include:

rectangular prisms

cubes

portions of prisms and cubes

similar shapes

Regular curved shapes

Regular curved shapes include:

cylinders

spheres

segments of cylinders and spheres

similar shapes

Transition pieces

Transition pieces include:

cones

pyramids

portions of cones and pyramids

square to round

tee piece

lobster back

similar shapes

Complex 3-D shapes

Complex 3-D shapes include:

other 3-D shapes which may need to be fabricated and which may be composed of a number of components of the above shapes

Alignment

Alignment may make reference to:

warp

weft

selvedge

other features of the sheet

Alignment also includes:

the nesting of lay flats to optimise the use of materials and minimise waste

Logs and reports

Logs and reports may be:

paper or electronic based

verbal reports

items found which require action

Appropriate action

Appropriate action includes:

determining problems needing action

determining possible fault causes

rectifying problem using appropriate solution within area of responsibility

following through items initiated until final resolution has occurred

reporting problems outside area of responsibility to designated person

Typical problems

Typical problems may include:

identifying directionality in sheet

identify a feature to provide alignment

products requiring multidirectional properties

Health, safety and environment (HSE)

All operations to which this unit applies are subject to stringent HSE requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence
