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.
The learning outcomes in this unit standard also contribute to the exit level outcomes required for the National Certificate in Engineering Machining (NQF level 4) and related qualifications. Qualifying learners can carry out internal and external grinding operations to produce complex components. The results are checked with a range of high precision measuring instruments. |
LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING |
This unit standard has been designed as part of a progression. It is one of a series of unit standards for grinding in the engineering machining skills area.
The credits allocated to this unit standard assume that a learner has already learned to: |
UNIT STANDARD RANGE |
The scope and level of this unit standard is limited to common commercial rubber applications and is determined by the ranges as indicated under the specific outcomes.
The learner should be able to work autonomously. |

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. |
