Unit Descriptor
Unit descriptor |
This unit covers writing and trialling a program for a range of CNC wire cut machines. Programming includes 2 axis tool paths, 4 axis conical cutting, and auto multi-cavity work pieces. |
Application of the Unit
Application of the unit |
This unit extends to programming a range of CNC wire cut machines. Programming includes 2 axis tool paths, 4 axis conical cutting, and auto multi-cavity work pieces. Technical difficulties are resolved in consultation with appropriate technical advisers. Work is carried out autonomously using predetermined standards of quality and safety. 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 : 2 |

Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
ELEMENT |
PERFORMANCE CRITERIA |
1. Write program |
1.1. Engineering drawings are understood and interpreted to define optimum tool path geometry. 1.2. Tool path is programmed using advanced operations, canned cycles and sub-routines or other appropriate sub-routines within system. 1.3. Program is written in standard code format, and confirmed and edited as necessary using appropriate routine and standard operating procedures. 1.4. Program is stored in accordance with standard operating procedures. 1.5. Operation sheet is produced to standard operating procedures. |
2. Trial program |
2.1. Program is downloaded, and machining parameters that may include wire offset, wire speed, power settings are selected. 2.2. Machine is prepared, work piece are loaded and aligned, datum and reference points are established in accordance with standard operating procedures. 2.3. Machine is operated in appropriate mode to test and prove program, work piece positioning. 2.4. Finished components are checked for conformance with drawing specifications. |

Evidence Guide
EVIDENCE GUIDE |
|
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 programming of CNC wire cut machines. 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 programming of CNC wire cut machines 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. |
Guidance information for assessment |
Range Statement
RANGE STATEMENT |
|
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. |
|
Program |
Includes setting of speeds, tolerances, taper angles, macros, nesting tool paths, chained linear tool paths and differential profiles |
