1.
Layout achieves economical manufacture consistently to design specification.
> Range: Layout includes choice of jigs, fixtures, cutting tools.
Manufacturing layout is capable of producing a product within specification.
> Range: Manufacturing layout: i.e. the manufacturing sequence as per the process plan.
The correct version of documents are used in the CNC machining process.
Choices are justified and issues relating to the choices are discussed and applied in accordance with requirements.
> Range: Processes and equipment; understanding of lean manufacturing techniques; knowledge of materials, manufacturing processes (including heat treatment) and equipment principles of metal cutting (including cutting fluids, speeds and feeds); measuring methods, equipment, tolerances, finishes and fits.
Work instructions are complete and clear.
> Range: Complete includes all operations and instructions.
> Range: Clear means language appropriate to users and correct use of terminology; all manufacturing aids are identified and specified.
Sequence of documents is logical.
Stage drawings are produced.
Processes relating to the development of work instructions are explained and discussed in accordance with requirements.
> Range: Engineering drawings, symbols (fits, surface finishes), relevant standards, (e.g. ISO, BS, DIN, API, SAE, IAS); using website to access relevant standards; knowledge of configuration management.
2.
Manufacturing and measurement processes are adjusted to meet design specifications.
> Range: Specifications include remarks, redline drawings.
Methods are robust and will mass-produce within the specifications.
> Range: Demonstrate statistically that the equipment will consistently produce the right quality component; calculate control limits; update data pack.
Explanation and discussion demonstrates a clear understanding of issues and principles related to process qualification.
> Range: Knowledge of manufacturing statistics, statistical process control, basic metrology, basic metallurgy, quality management systems applicable to his context (e.g. ISO 9000, motor industry specific QMS, armaments industry QMS); processes related to approval of the product for manufacturing.
3.
The manufacturing process is efficient and competitive.
> Range: Efficient and competitive: that which is within the limits of available machinery and resources.
Experience is used to revise and improve the layout and the data pack.
A systematic approach is taken to the problem solving.
> Range: Methods of problem solving, e.g. Ishikawa (fishbone) diagrams; 8-D TOPS (8 Discipline Team Oriented Problem Solving).
All available resources are consulted.
Statistical process control is explained in accordance with requirements.
> Range: Purpose of various types of charts; error conditions.
4.
Issues are communicated to the relevant personnel.
> Range: Relevant personnel include operators, supervisors, production and quality management; in small companies includes the customer.
> Range: Communication includes listening to and evaluating inputs from all sources, and using the information.
Performance of manufacturing personnel and learners is improved and meets requirements.
Issues related to communication, inter-personal relationships and diversity are explained and discussed.
Integrated assessment:
The integrated assessment should be based on a summative assessment guide. The guide will specify how the assessor will assess different aspects of the performance and will include:
Evaluating evidence in a portfolio of evidence, particularly projects which integrate various aspects of the qualification and which demonstrate the integration of all aspects of learning: fundamental and core; knowledge, skills and values; the development of the critical outcomes.
Observing and listening to the learner at work, both in primary activities as well as in other interactions, or in relevant simulations.
Asking questions and initiating short discussions to test understanding and to verify other evidence.
Looking at records and reports.
Formative and summative assessment of unit standards.
Assessment of competence for this qualification is based on experience acquired by the learner in the workplace, within the particular CNC production machining context. The assessment process should cover the explicit tasks required for the qualification as well as the understanding of the underlying concepts and principles. The assessment process should also establish how the learning process has advanced the Critical Cross-Field Outcomes.
The learner may choose in which language he/she wants to be assessed. This should be established as part of a process of preparing the learner for assessment and familiarising the learner with the approach being taken.
While this is primarily a workplace-based qualification, evidence from other areas of endeavour may be presented if pertinent to any of the Exit Level Outcomes.
Assessors should also evaluate evidence that the learner is able to perform consistently over a period of time.
