Overview

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

For Melbourne campuses

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.

Students will also be expected to demonstrate the following knowledge:
Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

• safe work practices and procedures and use of personal protective equipment (PPE)
• elements of NC and CNC program and the function of elements in controlling the operation of NC and CNC machine
• machining operations to be performed in the manufacture of the given part or product
• appropriate types of NC and CNC machines to perform the required machining operations
• machining operations to be controlled by the program to be written
tool path(s) to be followed when producing the part or product
• sequence of machining operations to be programmed and reasons for selecting the chosen tool path(s) and sequence of operations
• zero point of the NC and CNC machine
• canned cycles and sub-routines accessible in the particular NC and CNC machine and the application of each canned cycle and sub-routine available
• canned cycles and/or sub-routines to be used in the NC and CNC program and reasons for selecting the chosen canned cycles and/or sub-routines
• standard codes and their application used in the writing of NC and CNC programs
• procedures for writing NC and CNC programs in standard code format
• procedures for completing NC and CNC operation sheets and the information to be included
• relevant Australian Standards for programming multiple spindle and multiple axis NC and CNC machining centres
• procedures for manual operation of a NC and CNC machine
• reasons for testing and proving a NC and CNC program
• procedures for editing the NC and CNC program via the machine controller and the effects of editing on the operation of the NC and CNC machine and the part or product to be produced
• specifications of the part or product and measuring equipment/techniques to be used to check for conformance with specifications.
