This unit of competency defines the skills and knowledge required to write basic numerically controlled (NC) and computer numerically controlled (CNC) machine programs.
It extends to writing a program to describe simple machine operations, including tool paths, using appropriate software for machines. The program may use common M and G codes but does not include the programming of advanced operations using canned cycles and sub-routines. Technical difficulties are resolved in consultation with appropriate technical advisers.
Where basic programming of computer controlled thermal cutting machines is required unit MEM05054 Write basic NC/CNC programs for thermal cutting machines should also be selected.
Where additional machining skills in excess of unit MEM07005 Perform general machining are required appropriate units should also be selected.
Where programming of advanced operations using canned cycles and sub-routines is required unit MEM07019 Program NC and CNC machining centre 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 writing basic numerically controlled (NC) and computer numerically controlled (CNC) programs
• calculating coordinates for tooling and producing operation sheets for the program and process
• writing NC and CNC machine programs using standard code format
• producing NC/CNC operation sheets
• operating the machine to test it operates to specification undertaking any required editing of the program
• checking parts 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.
