This unit of competency defines the skills and knowledge required to identify numerically controlled (NC) and computer numerically controlled (CNC) machine program elements, write and trial a machine program for multiple spindle and multiple axis NC and CNC machining centres, and prepare an operation sheet.
The program may use common M and G codes and include the programming of advanced operations, using canned cycles and sub-routines. Programs are trialled and edited as necessary to adjust operation of centre. Technical difficulties are resolved in consultation with appropriate technical advisers.
Where additional machining skills in excess of MEM07005 Perform general machining are required appropriate units should also be selected.
Where the selection and use of power tools/hand held operations is required unit MEM18002 Use power tools/hand held operations should also be selected.
Assessment tasks will be designed to reinforce & extend knowledge and skill competence within set & controlled parameters in accordance with each unit’s learning outcomes & 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:
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:
• following work instructions, standard operating procedures (SOPs) and safe work practices
• identifying and interpreting specifications, charts, lists, drawings and other applicable reference documents in programming multiple spindle and multiple axis numerically controlled (NC) and computer numerically controlled (CNC) machining centres
• calculating coordinates for tooling and producing operation sheets for the program and process
• writing NC and CNC programs in standard code format and incorporating, where appropriate, canned cycles and sub-routines
• producing NC and CNC operation sheets in accordance with SOPs
• operating the multiple spindle and multiple axis NC and CNC machining centre to test it operates to specification undertaking any required editing of the program
• checking components or products for conformance to specifications.
The qualified trainer and assessor will provide teaching and learning materials as required in the form of workbooks produced by the Victoria University and/or via the Victoria University e-learning system.
