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. This unit standard applies to the maintenance and repair of tools, jigs, dies and fixtures and plastic injection moulds. The learner must demonstrate competence in either of the two skills areas to receive credits for this standard.

The learning outcomes in this unit standard also contribute to the exit level outcomes required for the National Certificate in Engineering Machining (NQF level 3) and related qualifications.

Qualifying learners can identify faults in, dismantle and/or maintain tools, dies, jigs and fixtures or plastic injection moulds in a workshop environment .

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

This unit standard has been designed as the start of a progression. It is one of a series of unit standards for the maintenance of tools, jigs, dies and fixtures.

The credits allocated to this unit standard assume that a learners has already learned to:

Manufacture production tooling to drawing or sample part

UNIT STANDARD RANGE

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 with minimal supervision.

Specific Outcomes and Assessment Criteria:

SPECIFIC OUTCOME 1

Identify and analyse defects in tooling.

OUTCOME NOTES

Inspect component parts or tools against drawing specifications and checklists

Determine defects

Determine sequence of operation for rectifying problems and conducting maintenance

Select hand tools, power tools and machines required

OUTCOME RANGE

Defects on tooling may include cutting edges; worn flanges; scratched surfaces; scrap fallaways; broken injection pads, springs, rubber pins and punches; slug build up.

Defects may be determined from produced components, production reports, tool inspections.

Tooling maintained and repaired includes a range of production tooling.

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.
