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 describes the essential skills and knowledge and their level required for this unit.
Knowledge of computer controlled machines and programming, including:
the elements of a basic NC/CNC/other program and their function in controlling the operation of computer controlled equipment
machining operations
type(s) of computer controlled equipment 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 equipment
standard codes used in the writing of programs
applications of standard codes in programming
procedures for writing programs in standard code format
procedures for completing operation sheets
the information to be included in operation sheets
influence of polymer properties on program requirements.
Competence also includes the ability to:
plan and sequence operations
check and clarify task related information.
Language, literacy and numeracy requirements
This unit requires the ability to read, interpret and follow information on written job instructions, specifications, standard operating procedures, charts, lists, drawings and other applicable reference documents
Writing is required to the level of completing workplace forms and operations sheets.
Mathematical techniques are required, eg in calculating coordinates of all relevant points on the part or product to be produced.
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.
Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.
Context
This competency applies to all work environments and sectors within the industry. It requires an understanding of the operation of all relevant equipment and processes but does not necessarily require them to be used personally.
Procedures
All operations are performed in accordance with procedures.
Procedures include all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.
Tools and equipment
This competency includes use of equipment and tools such as:
computer controlled machines
desktop computers.
Hazards
Typical hazards include machine operations hazards (when trialling programs).
Problems
'Anticipate and solve problems' means resolve a wide range of routine and non routine problems, using product and process knowledge to develop solutions to problems which do not have a known solution/s recorded in the procedures.
Typical problems may include:
machine malfunction
damage to machine/tools
machining errors.
Appropriate action for problems outside of area of responsibility may be reporting to
an appropriate person.
Appropriate action for solving problems within area of responsibility includes asking
questions and seeking assistance from appropriate person/sources
Variables
Key variables to be monitored include:
speed
output rate
product integrity and general conformance to specifications.
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.
