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 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 complex 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. |

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: setting up work to the required level of accuracy using appropriate precision measuring equipment setting and supporting work to avoid distortion on release of clamping devices selecting correct cutting tools or inserts as appropriate to turning operation selecting and using appropriate feeds and speeds performing complex turning operations - counter balancing work on face plates: mandrel work trepanning heavy (multi-tonne) shafts calculating cutting parameters, speeds and feeds reading, interpreting and following information on written job instructions, specifications, charts, lists, drawings and other applicable reference documents planning and sequencing operations checking and clarifying task related information entering routine and familiar information onto proformas and standard workplace forms checking for conformance to specifications using precision measurement equipment measuring components to specified tolerances performing numerical operations, geometry and calculations/formulae within the scope of this unit following oral instructions orally reporting information |
Required knowledge |
Look for evidence that confirms knowledge of: precision measuring equipment and measuring techniques within the scope of this unit reasons for selecting different measuring equipment procedures for accurately setting up work for a variety of techniques ISO or other standards applicable to cutting tool inserts cutting parameters for the given task feeds and speeds for complex turning operation(s) formulae and data relating to feeds and speeds techniques and procedures for carrying out the following turning operations: single-start thread cutting multi-start thread cutting internal blind hole thread cutting eccentrics copy turning taper turning techniques and procedures for carrying out the following turning operations: counter balancing work on face plates mandrel work trepanning heavy (multi-tonne) shafts hazards and control measures, including housekeeping use and application of personal protective equipment safe work practices and procedures |
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. | |
Lathe | Applicable to all classes of lathes used for complex turning operations |
Tooling | Cutting tools, form tools, boring bars, drills, reamers, thread chasers, tapping heads, taps etc. |
Complex turning | May include single-start and multi-start thread cutting, internal blind hole thread cutting, eccentrics, copy and taper turning, counterbalancing work on face plates, mandrel work, trepanning, heavy (multi-tonne) shafts etc. |
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.
Observation Checklist
| Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice | Yes | No | Comments/feedback |
|---|---|---|---|
| Sequence of operations including job set-up is determined for maximum efficiency and to meet job specifications. | |||
