Overview

This unit of competency been developed for engineering tradesperson - fabrication apprenticeship training and the recognition of trade-level skills in mark off/out of structural fabrications and shapes.



It applies to the marking off/out of general fabrications and shapes to specified measurements, tolerances and shapes using appropriate tools and equipment. Templates and patterns are produced as required.



Skills covered by this unit are generally applied in occupational and work situations associated with steel fabrication, boiler making or sheet metal work.



In a marine setting, it includes basic lofting/set out for construction of marine vessels and includes stem and transom development and use of tables of offsets that reflect chine and hull configuration. This includes lofting surfaces, straight edges, string lines, French curves and templates and marking out techniques apply to a range of materials and shapes.



Where more extensive lofting practices are required unit MEM09021 Interpret and produce drawings of curved 3-D shapes should also be selected.



Where marking out of general engineering components is required unit MEM12006 Mark off/out (general engineering) should also be selected.



Where the selection and use of tools is required unit MEM18001 Use hand tools and unit MEM18002 Use power tools/hand held operations, should also be selected as appropriate.

Assessment

For Melbourne campuses

Assessment tasks will be designed to reinforce and extend knowledge and skill competence within set and controlled parameters in accordance with each unit’s learning outcomes and performance criteria requirements, including the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.

Students will be expected to demonstrate the following required skills:

  • following work instructions, standard operating procedures (SOPs)and safe work practices;
  • identifying and interpreting specifications and drawings for fabrication requirements, including materials, measurements and tolerances, joining methods, standards and code requirements;
  • carrying out all marking off/out using appropriate marking out tools and equipment to specifications;
  • calculating measurements not shown on drawings, as required;
  • establishing and marking datum points;
  • selecting appropriate template material and producing templates to specifications;
  • storing templates, including labelling and identification, to procedures, as required;
  • developing patterns by selecting and applying appropriate development and/or measurement sequence and determining correct allowances for fabrication and assembly and transferring these measurements;
  • calculating allowances for fabrication and assembly, including shrinkage, thickness and inside/outside measurements, and transferring these measurements, and;
  • identifying and estimating quantities of materials from drawings with minimise wastage.

Students will also be expected to demonstrate the following knowledge:

  • safe work practices and procedures and use of personal protective equipment (PPE);
  • procedures for marking off/out and pattern development;
  • tools and equipment to be used in the preparation of the marking off/out;
  • datum points;
  • materials that can be used for the preparation of templates and their application;
  • manufacturing allowances that have to be considered when developing patterns;
  • template labelling and identification procedures and storage requirements of templates;
  • appropriate methods of development/marking off/out of a range of given objects;
  • appropriate fabrication and assembly allowances;
  • effects of material type and thickness on fabrication and assembly allowances;
  • sources of data on fabrication and assembly allowances;
  • relevant standards and codes and the meaning of symbols used;
  • requirements of the codes/standards applicable to the work to be done;
  • materials from which the component/assembly is to be manufactured, and;
  • benefits of minimising material wastage.

Required reading

The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by Victoria University and/or via the Victoria University e-learning system.
