URN: SEMPAT317
Business Sectors (Suites): Engineering Woodworking, Pattern and Model Making Suite 3
Developed by: Enginuity
Approved on: 28 Feb 2018

Overview

This standard identifies the competencies you need to assemble wood and composite pattern, corebox and model components using mechanical fixing devices and adhesives, in accordance with approved procedures. You will be required to select the appropriate tools and equipment to use, based on the operations to be performed and the type of components to be assembled, and to check that they are in a safe and serviceable condition. You will be expected to select the appropriate fixing devices and adhesives to use, based on the type, size and material of the components to be assembled. You will need to identify and create any datums that will be required to locate the components during the assembly process.

The size, shape and complexity of the parts to be assembled, and the finished equipment or model will vary, and it is anticipated that some components will be sub-assembled prior to the final assembly taking place. The assembly activities will also include making all necessary checks and adjustments to ensure that the assembled pattern equipment or model meets the required specification, that fasteners are securely tightened, and that the completed assembly is free from damage and has an appropriate cosmetic appearance.

Your responsibilities will require you to comply with organisational policy and procedures for the assembly activities undertaken, and to report any problems with the assembly activities, tools, adhesives or equipment used 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 the assembly of components to form wood and composite pattern equipment or models. You will understand the pattern equipment or model being assembled, and its application, and will know about the assembly techniques, components, equipment, relevant materials, adhesives and fastening devices, in adequate depth to provide a sound basis for carrying out the activities to the required specification. Your knowledge will be sufficient to enable you to identify damaged and out-of-tolerance components or sub-assemblies. You will know the implications of producing assemblies that do not meet specification on the castings, cores or models produced.

You will understand the safety precautions required when carrying out the assembly operations. 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:

  1. work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
  2. follow the relevant instructions, assembly drawings and any other specifications
  3. ensure that the specified components are available and that they are in a usable condition
  4. assemble components in their correct positions using appropriate methods and techniques

  5. secure the components using the specified connectors and securing devices

  6. produce components to the required quality and accuracy standards

  7. check the completed assembly to ensure that all operations have been completed and the finished assembly meets the required specification

  8. complete relevant data and documentation

  9. 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:

  1. the specific safety precautions to be taken whilst carrying out the assembly activities (such as any specific legislation, regulations or codes of practice relating to the activities, equipment or materials)
  2. the health and safety requirements of the work area in which you are carrying out the assembly activities, and the responsibility they place on you
  3. the personal protective equipment and clothing (PPE) to be worn during the assembly activities
  4. the hazards associated with producing wood and composite pattern or model assemblies, and how they can be minimised
  5. how to obtain the necessary job instructions, drawings and specifications for the assembly, and how to interpret the information
  6. how to identify the components to be used; component identification systems (such as codes, component orientation indicators)
  7. preparations to be undertaken on the components prior to fitting them into the assembly
  8. the assembly methods and procedures to be used, and the importance of adhering to these procedures
  9. how to mark out the necessary datum lines for the assembly operations
  10. how the components are to be aligned and positioned prior to securing them, and the tools and equipment that are used
  11. why some types of assembly require the use of jigs and gauges to aid the assembly
  12. the various mechanical fasteners that will be used to secure the pattern or model equipment, and their method of installation (including pins, nails, screws and special securing devices)
  13. the application of adhesives within the assembly activities, and the precautions that must be taken when working with them
  14. the quality control procedures to be followed during the assembly operations
  15. how to conduct any necessary checks to ensure the accuracy and quality of the pattern equipment or models produced
  16. recognising defects blemishes, poor alignment, ineffective fasteners, or damaged components
  17. how to check that the tools and equipment to be used are in a safe and serviceable condition
  18. the importance of ensuring that all tools are used correctly and within their permitted operating range
  19. why it is important to keep the tools and equipment clean and free from damage, to practice good housekeeping of tools and equipment and to
    maintain a clean and unobstructed working area
  20. the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
