MEM06002B
Perform hammer forging
Application
The unit applies to the use of hammer forging techniques on carbon and alloy steels using various techniques, tools, formers, power hammers and heating devices. Equipment range does not include drop and upset machinery, vacuum furnaces or rolling and extruding mill machinery. Band: A Unit Weight: 4 |
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1. Use hammer tools and formers | 1.1. Hammer tools and formers are correctly selected for specific forging technique. 1.2. Hammer tools and formers are used correctly. 1.3. Forging machine is set up and operated correctly. |
2. Apply hammer forging techniques | 2.1. Appropriate hammer forging technique is selected and applied. 2.2. Defects are recognised and appropriate rectification action is taken. 2.3. Correct techniques are applied to the handling of hot metal with regard to balancing and pivoting. 2.4. Correct heating process is applied. |
3. Select material | 3.1. Material calculations are made using volumes and weights that include provision for oxidisation and shrinkage. 3.2. Material is correctly selected for use with specific tools and formers. |
Required Skills
Required skills |
Look for evidence that confirms skills in: using hammer tools and formers setting up and operating forging machines following job instructions, drawings, specifications detecting forging defects rectifying forging techniques safely handling hot metal correctly heating material being forged calculating volume and weight of material |
Required knowledge |
Look for evidence that confirms knowledge of: hammer forging techniques the set up and operation of forging machines techniques for handling hot metal oxidisation/shrinkage allowances numerical operations and formulae for determining the volume and weight of material material specifications hazards and control measures associated with hammer forging, including housekeeping use and application of personal protective equipment safe work practices and procedures |
Evidence Required
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 apply hammer forging techniques to carbon and alloy steels using various techniques, tools, formers, power hammers and heating devices. |
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 hammer forging 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. |
