MEM07018C - Write basic NC/CNC programs

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: - reading, interpreting and following information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents; - planning and sequencing operations; - checking and clarifying task related information; - calculating coordinates of all relevant points on the part or product to be produced; - writing NC/CNC program in standard code format; - producing NC/CNC operation sheet(s); - operating NC/CNC machine safely in manual mode; - editing NC/CNC program, and; - checking parts or products for conformance to specifications.Students will also be expected to demonstrate the following knowledge: - the elements of a basic NC/CNC program; - the function of elements in controlling the operation of an NC/CNC machine; - machining operations; - type(s) of NC/CNC machine and their applications; - machining operations controlled by program; - the tool path(s) to be followed when producing a part or product; - the sequence of machining operations; - the reasons for selecting tool path(s) and sequence of operations; - the zero point of the NC/CNC machine; - standard codes used in the writing of NC/CNC programs; - applications of standard codes in NC/CNC programming; - procedures for writing NC/CNC programs in standard code format; - procedures for completing NC/CNC operation sheets; - the information to be included in NC/CNC operation sheets; - procedures for manual operation of the NC/CNC machine; - reasons for testing and proving the NC/CNC program; - procedures for editing the NC/CNC program via the machine controller; - the effects of editing on the operation of the NC/CNC machine and the part or product to be produced; - the measuring equipment/techniques used to check for conformance to specification; - hazards and control measures associated with numerical and computer controlled machines, including housekeeping, and; - safe work practices and procedures.
