Modification History

Release 1. Supersedes and is equivalent to MEM07019C Program NC/CNC machining centre

Application

This unit of competency defines the skills and knowledge required to write and trial programs for numerically controlled (NC) and computer numerically controlled (CNC) machining centres.

The program may use common M and G codes and includes 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 the selection and use of power tools/hand held operations is required unit MEM18002 Use power tools/hand held operations should also be selected.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Foundation Skills

This section describes those required skills (reading, writing, oral communication and numeracy) that are essential to workplace performance in this unit of competency.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.

Range of Conditions

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, accessibility of the item, and local industry and regional contexts) are included.

Basic machines incorporate one (1) or more of the following: 
  • single spindles
  • single tools turrets
  • B axis angular
  • tool changers
  • component loaders of a pallet type, but excludes multiple spindles and multiple axis

Assessment requirements

Modification History

Release 1. Supersedes and is equivalent to MEM07019C Program NC/CNC machining centre

Performance Evidence

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 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/CNC program in standard code format and incorporating, where appropriate, canned cycles and sub-routines
  • producing NC/CNC operation sheets in accordance with SOPs
  • operating the machine centre to test it operates to specification including undertaking any required editing of the program
  • checking components or products for conformance to specifications.

Knowledge Evidence

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 machines
  • 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 paths to be followed when producing the part or product and the sequence and reasons for selecting the sequence of machining operations to be programmed
  • zero point of the NC and CNC machine
  • canned cycles and sub-routines accessible in a 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 information to be included
  • relevant Australian Standards for programming of NC and CNC machine centres
