Set and edit computer controlled machines/processes
Assessment tool
Version 1.0
Issue Date: May 2024
The unit applies to any computer or numerically controlled machine or process. Applications may include NC/CNC machines and industrial robots.
Editing applies to identifying and accessing programs in edit mode in order to make changes associated with speeds, feed and operational sequence. Changes are generally made in situ.
Work is performed to established processes, practices and specifications. Machine operations may include welding, thermal cutting, metal cutting, forming and shaping etc.
All work and work practices are performed to instructions, plans and specifications as appropriate. Technical difficulties are resolved in consultation with appropriate technical advisers. Work is carried out autonomously to predetermined standards of quality and safety.
Where additional machining skills in excess of Unit MEM07005C (Perform general machining) are required then appropriate units should also be selected.
For setting and editing computer controlled thermal cutting machines, see Unit MEM05053A (Set and edit computer controlled thermal cutting machines)
Band:
This unit has dual status and is to be regarded as both a Specialisation band A unit and Specialisation band B unit for progression to C7 (AQF level IV).
Unit Weight: 4
This unit covers setting work holding fixtures/devices/tools, setting tooling offsets, trialling the program, instructing the operator and replacing worn or damaged tooling.
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 set and edit computer controlled machines/processes. 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. Where assessment occurs off the job, i.e. the candidate is not in productive work, 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 setting and editing computer controlled machines/processes 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, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents planning and sequencing operations checking and clarifying task related information attaching ancillary devices mounting work holding devices measuring tool offsets entering and verifying tool offsets producing and checking first-off samples editing programs instructing machine operator on the sequence of operations following safety procedures identifying worn or damaged tooling and taking appropriate corrective action |
Required knowledge |
Look for evidence that confirms knowledge of: ancillary equipment and its applications procedures for attaching the ancillary device(s) to the NC/CNC machine work holding devices, their application and procedures for mounting them location of work holding fixtures/devices/tools relative to the machine zero or datum reasons for establishing tool offsets procedures and devices for measuring tool offsets procedures for entering and verifying tool offset procedures for adjusting tool offsets operating procedures safety features and equipment measuring devices/ techniques for checking the parts or product effects of changes to cutting feeds and speeds the impact of changes to the sequence of operations on the part or product to be produced procedures for editing programs via the machine controller the sequence of operations of the machine/process examples of worn or damaged tooling the effects of worn or damaged tooling the corrective action to be taken for worn or damaged tooling hazards and control measures associated with computer controlled machines, including housekeeping 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. | |
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 |
