Modifying and repairing pattern, corebox or model equipment
Overview
This standard identifies the competencies you need to carry out modifications and repairs to existing patterns, coreboxes or models, in accordance with approved procedures. The equipment may have to be modified for a number of reasons, which could include performance out of specification, inherent design problems, changes to customer specification, or casting/production problems. The type of equipment being modified or repaired will include loose or plated patterns (with and without cores), solid turnout, split and multi-part coreboxes, and various types of full and scale models.
The modifications or repairs will be carried out using a combination of hand and machine skills, and you will be expected to select the relevant and current documentation relating to the modifications or repairs, to determine the methods to be used, and to obtain the tools and equipment required for the modification or repair, checking that they are in a safe and usable condition. In carrying out the modification or repair, you will be required to follow safe and approved procedures and techniques at all times.
The materials used to modify or repair the equipment will, in the main, compare with the original part but, for operational purposes, different materials could be substituted, provided these materials will not affect serviceability of the equipment. The pattern or model equipment, and its components, could be modified using a number of methods and techniques including, where appropriate, adjusting, removing and replacing, repairing or manufacturing new components. Modified component parts will be checked for accuracy, security, completeness and function, as per the specification.
Your responsibilities will require you to comply with organisational policy and procedures for the modification activities undertaken, and to report any problems with the modification activities, materials or equipment that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work with minimum supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.
Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying modification and repair methods, techniques and procedures to pattern and model equipment. You will understand the equipment being modified, including its application, and the reason for modification, and will know about the tools and equipment to be used, in adequate depth to provide a sound basis for carrying out the activities to the required specification.
You will understand the safety precautions required when carrying out the modification or repair activities. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.
Performance criteria
You must be able to:
- work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
- obtain the relevant specification and job instructions for the modification or repair being performed
- confirm and agree what modification or repair is to be carried out to meet the specification
- determine how the pattern, corebox or model equipment will need to be prepared for the modification or repair being carried out
- check that any materials and equipment required are available and that they are suitable for the work to be carried out
- carry out the modification or repair to achieve the required changes in line with agreed instructions and specifications
- complete all relevant documentation in accordance with organisational requirements
- deal promptly and effectively with problems within your control and report those that cannot be solved
Knowledge and Understanding
You need to know and understand:
- the specific safety precautions to be taken whilst carrying out the modification on the pattern, corebox or model equipment (such as any specific legislation, regulations or codes of practice relating to the activities, equipment or materials)
- the health and safety requirements of the work area in which you are carrying out the modification activities, and the responsibility they place on you
- COSHH regulations pertinent to the substances used in the modification process
- the hazards associated with modifying pattern, corebox and model equipment, and the tools and equipment that are used, and how these hazards can be minimised
- the personal protective equipment and clothing (PPE) to be worn during the modification activities
- the various types of drawing and specifications that are used during the modification
- how to use and extract information from engineering drawings and related specifications (to include symbols and conventions to appropriate BS or ISO standards in relation to work undertaken)
- how to interpret first and third angle drawings, imperial and metric systems of measurement, workpiece reference points and system of tolerancing
- the function of the pattern, corebox or model equipment being modified or repaired (to include plated patterns, loose patterns, solid, split and multi-part coreboxes, full-size and scale models)
- the reasons why pattern, coreboxes and model equipment may require modification
- preparations that need to be undertaken on the components prior to carrying out the modification
- how the different materials used in the original equipment may affect the choice of repair/modification methods
- the various methods that could be used to modify assemblies (such as adjust, remove and replace, repair and manufacture)
- the concepts and techniques that can be used, where appropriate, to modify the assembly (such as by machining, fitting, bonding, filling and blending)
- the benefits and limitations of the various types of locating and securing devices used on patterns, coreboxes and model equipment
- why the cost of the modification or repair needs to be determined before commencing work
- the quality control procedures to be followed during the modification, and the importance of adhering to them
- how to conduct any necessary checks to ensure the accuracy, position, security, function and completeness of the modification
- the methods and equipment used to transport, lift and handle components and assemblies
- how to check that the tools and equipment to be used are correctly calibrated and are in a safe and serviceable condition
- the importance of ensuring that all tools are used correctly and within their permitted operating range
- the importance of ensuring that all tools, equipment and components are accounted for and returned to their correct location on completion of the modification activities
- problems associated with carrying out modifications on pattern, corebox and model equipment, and the importance of informing the appropriate people of non-conformances
- the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
