Unit details

Study level:
Vocational and further education (TAFE)
Unit code:


MEM05037C - Perform geometric development

MEM09002B - Interpret technical drawing

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: - performing material calculations; - carrying out geometric development; - establishing datum points; - calculating allowances; - marking out techniques; - producing template/patterns; - labelling and storing template/patterns; - developing template/patterns; - determining and transferring fabrication and assembly allowances; - applying relevant codes/standards; - determining material and component quantities by applying geometric formulae, and; - applying principles for optimising material use and minimising material wastage.Students will also be expected to demonstrate the following knowledge: - tools, equipment, techniques in template/patterns development; - datum points; - geometrical principles and formulae; - calculations of allowances: - template/patterns materials; - template/patterns development; - manufacturers' allowances on materials; - procedures for making template/patterns; - template/patterns labelling, identification and storage; - fabrication and assembly allowances; - effects of material type/thickness on fabrication and assembly allowances; - sources of data on fabrication/assembly allowances; - relevant standards, codes, symbols; - fabrication materials; - optimising material use and minimising material wastage, and; - safe work practices and procedures.
