Elements and Performance Criteria

1. Determine drawing requirements
   • Check purpose, scope and information requirements for drawing
   • Interpret available information relevant to project and work requirements and identify and address further information needs
   • Identify and prepare equipment required to complete work
   • Identify and access organisational files, templates and symbols as required for work

Required Skills

Required skills

Required skills include literacy skills sufficient to read and interpret instructions relevant codes of practice and specifications for drawings work using computer technologies and navigating software numeracy skills sufficient to interpret technical information and conduct mathematical problem solving as required in the scope of this unit using and maintaining drawing equipment applying spatial principles to achieve scale and proportion interpersonal skills to consult with other disciplines drafting skills applying symbols schedules and legends to the drawing arranging the views in a logical manner and in accordance with AS Technical drawing General principles correctly using line thickness and construction to identify parts using engineering and manufacturer catalogues tables standards and specifications applying surface texture symbols to comply to engineers requirements applying toleranced dimensions to a detail drawing reading and selecting the correct key keyway and keyseat sizes given a specified condition using the appropriate tables reading and selecting correct toleranced dimensions to meet the required Class of Fit as selected by the engineer or from the specifications selecting a bearing or seal from engineering and manufacturer catalogues tables standards and specifications to fit into housings and over shafts converting between unilateral bilateral and limit of size or direct tolerances applying tolerances to meet the individual fit classifications between a shaft and hole clearance interference and transition filing drawings according to workplace procedures

Required knowledge

Required knowledge includes general knowledge of different approaches to drawing awareness of copyright and intellectual property issues and legislation in relation to drawing environmental and OHS issues associated with the tools and materials used for drawing quality assurance procedures company standards for CAD order of drawing process company checking procedures for drawings layout and presentation the standards applicable to the work to be undertaken the process of checking the completed drawing the process of storing paper drawings and electronic drawing files the International System of Units SI the different types of bearings used in the manufacture of an engineering project the different types of seals used in the manufacture of an engineering project surface texture finishes and machining processes geometric tolerances with regard to the roundness straightness flatness concentricity and so on of an engineering component terminology associated with the preparation of mechanical drawings

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to interpret and apply drawing specifications and industry standards in the production of mechanical drawings which detail bearings seals and other componentry
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts Specifically the candidate must be able to work within typical siteteamwork structures and methods apply worksite communication procedures comply with organisational policies and procedures including quality requirements participate in work meetings comply with quality requirements use industry terminology apply appropriate safety procedures demonstrate industry knowledge including industry size scope of work and economic issues relevant industrial awards and enterprise agreements relevant legislative provisions covering discrimination and equal employment opportunity
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team Where applicable reasonable adjustment must be made to work environments and training situations to accommodate ethnicity age gender demographics and disability Access must be provided to appropriate learning andor assessment support when required Where applicable physical resources should include equipment modified for people with disabilities This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with drafting or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials
