Unit of competency details

Unit descriptor 

This unit covers producing 2D CAM code files, managing files, managing tools and associated customisation of installed software including the use of macros, menus and default settings.

Application of the unit 

This unit typically applies in a manufacturing setting where components are machined or processed within a CAM environment. Code files would be produced from existing CAD models.

If 2D CAD models are produced, Unit MEM09009C (Create 2D drawings using computer aided design system) should also be selected. Where components are machined following development of code files, appropriate CNC machining units should also be selected.

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.

REQUIRED SKILLS AND KNOWLEDGE 

This section describes the skills and knowledge required for this unit.

Required skills 

Look for evidence that confirms skills in:

• interpreting relevant manuals, instructions and operating procedures
• customising relevant system variables
• customising menus and system defaults
• developing macros
• manipulating models
• linking model entities to database attributes
• creating manufacturing data for various operations and processes
• importing CAD files
• saving and managing CAM files

Required knowledge 

Look for evidence that confirms knowledge of:

• model features of the CAM software system
• operation of the CAM software system
• the system variables and procedures for customising
• procedures for customising user interface
• procedures for customising system defaults
• procedures for developing macros
• procedures for linking model entities to database attributes
• CAD file conversion
• CAM file formats
• procedures for saving and managing CAM files

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 create 2D code files using a computer aided manufacture system. 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 creating 2D code files, 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.
