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.

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

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the assessment tasks)

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

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
Machine operations include one (1) or more of the following:	welding thermal cutting metal cutting forming and shaping

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
