Elements and Performance Criteria

  1. Prepare for work
  2. Set up for machining and processing
  3. Operate machining and processing centres
  4. Clean up work area and maintain equipment
  5. Anticipate and solve problems

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Regulatory framework

The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used.

Applicable legislation, regulations, standards and codes of practice include:

health, safety and environmental (HSE) legislation, regulations and codes of practice relevant to the workplace, manual handling and hazardous materials

Australian/international standards relevant to the materials being used and products being made

any relevant licence and certification requirements.

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 such requirements the legislative requirements take precedence.

Procedures

All operations must be performed in accordance with relevant procedures.

Procedures are written, verbal, visual, computer-based or in some other form, and include one or any combination of:

emergency procedures

work instructions

standard operating procedures (SOPs)

safe work method statements (SWMS)

formulas/recipes

batch sheets

temporary instructions

any similar instructions provided for the smooth running of the plant.

Tools and equipment

Tools and equipment include:

multi axis router which may be moving bed or moving bridge type machine

ancillary equipment that is integral to the process

stand-alone or integral computing systems

work clamps, jigs, fixtures, vacuum tables

machine specific tools.

Additional tools and equipment will be selected as required from:

measuring devices

relevant personal protective equipment (PPE).

Hazards

Hazards must be identified and controlled. Identifying hazards requires consideration of:

fumes/vapours

weight, shape, volume of materials to be handled

hazardous products and materials

rotational equipment or vibration

sharp edges, protrusions or obstructions

slippery surfaces, spills or leaks

smoke, dust or other atmospheric hazards

high temperatures

electricity

gas

gases and liquids under pressure

structural hazards

equipment failures

machinery, equipment and product mass

other hazards that might arise.

Problems

Routine and non-routine problems must be resolved.

Non-routine problems must be resolved by applying operational knowledge to develop new solutions, either individually or in collaboration with relevant experts, to:

determine problems needing action

determine possible fault causes

develop solutions to problems which do not have a known solution

follow through items initiated until final resolution has occurred

report problems outside area of responsibility to designated person.

Non-routine problems are unexpected problems or variations of previous problems and include one or more of:

material degradation

tool selection and design problems

emergency situations

intermittent faults.

Operational knowledge includes one or more of:

procedures

training

technical information, such as journals and engineering specifications

remembered experience

relevant knowledge obtained from appropriate people.

Routine problems are predictable and have known solutions and include one or more of:

processing problems

equipment malfunctions

out-of-specification equipment operation

problems with work clamps, jigs and fixtures.


Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria and demonstrate the ability to:

read and interpret drawings, procedures, job specifications, instruments/control panels, material labels and safety data sheets (SDS)

set up program for router to meet job requirements, including one or more of:

converting a computer aided design to data points for separate loading to the router's controller

downloading or passing computer design data (CAD or CAM data) to the machining centre

digitising directly using a 'teach pendant'

other computer programming process

set up equipment, tools and materials

start up and operate the equipment

monitor key variables, including:

speeds, including tool speed and travel

surface finish and appearance

output rate

product integrity and general conformance to specification

make adjustments to remedy faults and nonconformity

maintain output and product quality using appropriate instruments, controls, test information and readings

safely shut down equipment in normal and abnormal circumstances

leave machine in appropriate condition with any required locks, tags or notices

identify hazards and apply relevant hazard controls

apply safety procedures

apply housekeeping procedures

apply waste management procedures

recognise early warning signs of equipment/processes needing attention or with potential problems

distinguish between causes of problems, including:

operational problems

instrument failure/malfunction

electrical failure/malfunction

mechanical failure/malfunction

wrong readings

equipment design deficiencies

process variables

raw material variations/degradation

process abnormalities

procedural errors

recognise and prioritise problems requiring action

resolve routine and non-routine problems

communicate effectively with team/work group and supervisors

complete workplace records

do basic arithmetical manipulations, including additions, subtractions, divisions, fractions and percentages.


Knowledge Evidence

Must provide evidence that demonstrates knowledge relevant to their job sufficient to operate independently and to solve routine and non-routine problems, including knowledge of:

types, characteristics, uses and limitations of multi-axis routers

program and machine theory, practices and techniques as applicable to multi-axis routers

function and operating principles of multi-axis router and ancillary equipment

impact of variations in machine process on product quality and production output

factors which may affect product quality or production output and appropriate remedies

common adjustments in process variables and their impact on product quality and production output

impact of variations in raw materials and equipment operation in relation to final product

routine and non-routine problems that may arise, the range of possible causes and appropriate actions

organisation procedures relevant to the work environment/job role
