Marking out wood and composite materials

​

This standard identifies the competencies you need to prepare for and mark out materials and components used in engineering woodworking and model making, in accordance with approved procedures. You will need to interpret correctly the information contained in the drawings, instructions and specifications, in order to mark out the materials and components accurately and correctly. You will be required to select the appropriate marking-out equipment to be used, based on the features to be marked out and the accuracy required. You will need to use these instruments to mark out datums, profiles, simple joints, hole positions, assembly positions and cutting lines which will be followed when producing the required components. Materials to be marked out will include softwoods, hardwoods and composites, which may be in sheet form, stock sections, or part-manufactured components or sub-assemblies.

Your responsibilities will require you to comply with organisational policy and procedures for the marking-out activities undertaken, and to report any problems with the marking-out equipment, materials or activities 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 marking-out methods and procedures to engineering woodworking and model making components. Your knowledge will be sufficient to enable you to identify incomplete, conflicting or inadequate information, and to carry out the marking-out activities to the required specification. You will know about the various tools that can be used in the marking-out process and why it is important to mark out accurately and legibly.

You will understand the safety precautions required when working with marking-out mediums, tools and equipment, and will be required to demonstrate safe working practices throughout. You will understand the responsibility you owe to yourself and others in the workplace

​

1. work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
2. obtain and use the correct information for marking out
3. obtain the appropriate marking-out equipment and check that it is in a usable condition
4. prepare suitable datums and marking-out surfaces
5. mark out components using appropriate methods

6. check that the marking out complies with the specification

7. complete relevant data and documentation

8. deal promptly and effectively with problems within your control and report those that cannot be resolved

​

1. the specific safety precautions to be taken when marking out wood and composite materials, and with the tools and equipment that are used
2. hazards associated with the marking-out activities (such as marking-out equipment used, lifting and handling sheet material, long lengths of materials, splinters from wood), and how they can be minimised
3. the process to be adopted to obtain the required drawings and job instructions
4. how to extract information from engineering drawings and related specifications (to include symbols and conventions in relation to work undertaken, first and third angle projections)
5. principles of marking out and the type of equipment used
6. the range of operations that the various marking-out equipment is capable of performing
7. how to prepare the materials in readiness for the marking-out activities, in order to enhance clarity, accuracy and safety (such as visually checking for defects, preparing the materials, removing sharp corners and edges)
8. how to select and establish suitable datums
9. the importance of ensuring that marking out is undertaken from the selected datums, and the possible effects of working from different datums
10. methods of holding and supporting workpieces during the marking-out activities, and equipment that can be used
11. use of marking-out conventions when marking out the workpiece (including datums; cutting guidelines; square and rectangular profiles; circular and radial profiles; angles; holes which are linearly positioned, boxed and on pitch circles)
12. the use of geometrical construction methods applied to marking out
13. ways of laying out the marking-out shapes or patterns to maximise the use of materials
14. setting and adjusting tools (such as squares, protractors, marking gauges)
15. the importance of using tools only for the purpose intended; the care that is required when using the equipment and tools; the proper way of storing tools and equipment between operations
16. the need for clear lines and dimensional accuracy in marking out to specification and drawing requirements
17. what can go wrong with the marking-out activities, and how these can be avoided
18. standards to be attained and company quality control procedures
19. the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve
