MEM07030C
Perform metal spinning lathe operations (basic)
Application
This unit applies to manual metal spinning of sheet metals. Spinning does not include hot spinning procedures. Tool use will include either hand and/or slide tooling of varying design and materials. Where operational maintenance requires dismantling and replacing components, Unit MEM18055B (Dismantle, replace and assemble engineering components) should also be selected. If annealing is required, the appropriate unit MEM05007C (Perform manual heating and thermal cutting) should also be selected. Where disc blanks are cut out using a dedicated circle cutter or similar, Unit MEM07032B (Use workshop machines for basic operations) should also be selected. If the interpretation of technical drawings is required Unit MEM09002B (Interpret technical drawings) should also be selected. Band: A Unit Weight: 8 |

Required Skills
Required skills |
Look for evidence that confirms skills in: reading and interpreting routine information on written job instructions, specifications and standard operating procedures. May include drawings following oral instruction entering routine and familiar information onto proformas and standard workplace forms using all basic metal spinning tools minimising damage and defects calculating disc size and lathe speed undertaking manual handling related to spinning products using appropriate techniques, tools and equipment to measure materials and spinnings |
Required knowledge |
Look for evidence that confirms knowledge of: 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 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 (basic) |
Evidence Required
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 basic metal spinning lathe operations. 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 performing basic 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 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. |
