In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
The skills, values and knowledge reflected in this unit standard are required by people in the field of engineering machining.

Qualifying learners are able to write 2D or 2 ? D / 3D CNC programmes describing simple tool paths using M and G codes. They are able to set and operate a CNC milling machine or lathe including editing a CNC programme to change speed, feed and operational sequence requirements. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
This unit standard has been designed as part of a progression.

The credits allocated to this unit standard assume that a learner has already learned to
  • Produce complex components using milling machines
    OR
  • Produce complex components using lathes 
    		•

    UNIT STANDARD RANGE 
  • The CNC programmes written may apply to either a CNC lathe or milling machine.
  • Problems of a technical nature are resolved in consultation with technical advisors.
  • The scope and level of this unit standard is determined by the ranges as indicated under the specific outcomes.
  • The learner should be able to work autonomously. 
    		•

    Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1 
    Prepare and write programme. 
    OUTCOME NOTES 
  • Interpret drawings and documentation and define tool path geometry
  • Calculate tool path co-ordinates
  • Define programme elements together with machine code functions needed for incorporation into the programme
  • Select appropriate tools for the task
  • Select speeds, feeds and depth of cut
  • Write programme and operation sheet in required format for machine operation 
    		•
    OUTCOME RANGE 
    CNC programming is limited to 2D or 2 ? D/3D programmes using M and G codes.

    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    The assessment will be governed by the policies and guidelines of the MERSETA Education and Training Quality Assuror who has jurisdiction over this field of learning. The assessor will (at the very least) be accredited and have a technical qualification in this learning area.

    The learner can be assessed in the language of his/her choice although s/he has to report incidents or conditions to someone else. The learner will be assessed on his/her ability to report in the language commonly used in his/her working environment.

    The learner will be assessed in the workplace but s/he can submit documents, projects, test results and assignments that were not produced in the workplace.

    The learner can be assessed against this unit standard to obtain credits or as part of an integrated assessment for a qualification.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
