Application

This unit of competency defines the skills and knowledge required to perform basic metal spinning lathe (excluding computer numerically controlled [CNC]) operations.

It applies to manual metal spinning of sheet metals of varying thicknesses but does not include hot spinning procedures. Tool use will include either hand and/or slide tooling of varying design and materials.

Where annealing is required unit MEM05007 Perform manual heating and thermal cutting should also be selected.

Where disc blanks are required to be cut out using a dedicated circle cutter or similar unit MEM07032 Use workshop machines for basic operations should also be selected.

Where operational maintenance requires dismantling and replacing components unit MEM18055 Dismantle, replace and assemble engineering components should also be selected.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

What You'll Learn

Assessment Requirements

Performance Evidence

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

identifying and interpreting specifications and other applicable reference documents for spinning lathe operations

calculating disc size and spinning speeds

selecting chucks and mounting disc for forming

performing spinning operation using appropriate accessories to produce finished work that meets specifications

removing finished work and storing to minimise damage

performing operational maintenance on the lathe and related equipment and making any required adjustments to lubrication levels.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

correct sequence of spinning operation

types of spinning tools, their functions and requirements for maintaining tools

types of damage and defects (e.g. tool marks, cracking, stress marks, thinning and incorrect finish)

spinning lathe operation

why and how lathe speed is calculated

reasons for types of form chuck mounting

function and operation of accessories for basic spinning and methods used for each process

correct methods for stacking and protecting finished product.

Assessment Conditions

Assessors must:

have vocational competency in performing basic metal spinning lathe operations at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
