Version 1.0
Issue Date: May 2024
Machining is undertaken on a range of non- CNC (computer numerical controlled) machines
This unit covers determining the job requirements and sequence of operations, selecting and mounting tools, performing the machining, measuring the components, and adjusting and maintaining a range of standard machine tools.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
Prerequisites
Path 1
MEM09002B Interpret technical drawing
MEM12023A Perform engineering measurements
MEM18001C Use hand tools
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 specifies the evidence required to demonstrate achievement in the unit of competency as a whole. It must be read in conjunction with the unit descriptor, performance criteria, range statement and the assessment guidelines for the Metal and Engineering Training Package | |
Overview of assessment requirements | A person who demonstrates competency in this unit must be able to perform general machining. Competency in this unit cannot be claimed until all prerequisites have been satisfied. |
Context of 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. |
Interdependent assessment | This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with performing general machining 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. |
Consistency of performance | 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. |
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 | |
planning and sequencing operations | |
preparing operational work plan | |
sharpening and shaping cutting tools | |
identifying worn or damaged cutting tools | |
correct mounting and positioning of cutting tools | |
basic marking out of materials | |
setting machining parameters to achieve the job requirements and maximise tool life | |
using appropriate and sufficient clamping/mounting of the work piece | |
using coolant/lubricant correctly | |
checking for conformance to specifications | |
measuring to specified tolerances and dimensions | |
Required knowledge | Look for evidence that confirms knowledge of: |
reasons for selecting the chosen sequence of operations | |
methods of work holding | |
basic marking out techniques including datum points/lines etc. | |
geometry of cutting tools for a range of materials and applications | |
benefits of using correctly sharpened cutting tools | |
machine operation | |
selection of feeds and speeds to suit a range of materials and operations within the scope of this unit | |
correct methods of mounting a variety of cutting tools | |
safety issues with regard to correct clamping, guards, shields etc. | |
tolerances, limits of size | |
situations indicating the need for machine adjustment, lubrication and cleaning | |
techniques, tools and equipment to measure materials and machined components | |
use and application of personal protective equipment | |
safe work practices and procedures | |
hazards and control measures associated with general machining | |

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.
The range statement provides information about the context in which the unit of competency is carried out. The variables and scope cater for different work requirements, work practices and knowledge between States, Territories and the Commonwealth, and between organisations and workplaces. The range statement relates to the unit as a whole and provides a focus for assessment. Text in italics in the performance criteria is explained here. The following variables may be present and may include, but are not limited to, the examples listed under the scope. All work is undertaken to relevant legislative requirements, where applicable | |
Variable | Scope |
Operations | Parallel cutting, slotting, planing, drilling, knurling, cutting flats, non-precision surface grinding operations etc. |
Material | Ferrous and non ferrous |
Tools | Cutting tools and accessories, measuring devices |
Marking out techniques | Basic marking out techniques using calipers, steel rules, dividers, scribers etc. |
Machining parameters | Speeds, feeds, stops, coolant and cutting lubricants etc. Machines include lathes, mills, planers, shapers, radial arm drills, slotters, surface grinder etc. |
Maintenance and adjustments | Slide and collar adjustment, cleaning and lubrication |
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
