Perform metal spinning lathe operations (complex)
Assessment tool
Version 1.0
Issue Date: June 2024
This unit applies to complex spinning operations which require preparation of form chucks, oval spinning, thread spinning, or jobs requiring higher precision or quality using mainly brass and brass alloys. This unit also requires the use of a wide range of spinning accessories and processes, including the use of annealing.
Where there is a requirement to join spun materials or products in addition to, or instead of, (the spinning operation of) swaging, the following units may also be required: Unit MEM05003B (Perform soft soldering), Unit MEM05006B (Perform brazing and/or silver soldering), or Unit MEM05004C (Perform routine oxy acetylene welding [fuel gas welding]), or Unit MEM05012C (Perform routine manual metal arc welding)
Band: A
Unit Weight: 4
This unit covers performing complex metal spinning operations (excluding CNC), using a variety of advanced processes, spinning tools and accessories.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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 perform complex spinning operations using a range of metal spinning lathes, accessories and measuring equipment. 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 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 performing complex metal spinning lathe operations 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 should not require language, literacy and numeracy skills beyond those required in this unit. 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. |

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Required skills |
Look for evidence that confirms skills in: reading and interpreting information on written job instructions, specifications and standard operating procedures. May include drawings entering information onto proformas and standard workplace forms following oral instruction using all types of metal spinning tools and accessories calculating disc size and lathe speed including angles and radius manual handling related to spinning products coordinating use of multi-slides and tools, feeds and speeds producing complex spinning shapes using a variety of processes and techniques |
Required knowledge |
Look for evidence that confirms knowledge of: complex spinning operations, processes and techniques requirements for maintaining tools and manufacturing form chucks types of damage and defects e.g. tool marks, cracking, stress marks, thinning and incorrect finish function and operation of accessories methods used for each process methods for stacking and protecting finished product use and application of personal protective equipment safe work practices and procedures hazards and control measures associated with metal spinning lathe operations (complex) |
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. | |
Tools | Spinning tools, planishing tools, backstick, trimming, beading tools, back centre, holding and sectional chucks, tee-rest, compound and additional slides, recessed and cranked followers, rollers and knurling wheels etc. |
Complex spinning operations | Spinning, beading, recessing, oval spinning, screw forming, (thread spinning) seaming, swaging, trimming finishing, annealing, pickling, combined angles and multi-radii |
Metals | Steels, aluminium, monel, copper, brass, brass alloys, zinc, pewter, silver, gold, tin, etc., of varying thicknesses |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
