Unit of competency details

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

ELEMENT

PERFORMANCE CRITERIA

1 Prepare for lathe operations

1.1 Machining requirements are identified

1.2 Materials are to be machined collected

1.3 Lathe equipment is set up for operation

1.4 Pre-operational equipment checks are conducted

1.5 Health and safety hazards / maintenance requirements are identified and reported to appropriate personnel according to workplace reporting procedures

2 Operate lathe to achieve specifications

2.1 Machining parameters are set to meet job requirements

2.2 Materials are accurately positioned for lathe operation

2.3 The lathe is started, operated and shut down according to operating procedures and manufacturer's specification

2.4 Work is checked against specification

2.5 Non-conforming components are identified and corrected as required

2.6 Basic routine maintenance is carried out as required

2.7 The workplace meets housekeeping standards

Required skills includes:

Ability to: 

• identify lathe requirements which may require interpretation of technical drawings or sketches
• select, fit and use personal protective clothing and/or equipment
• confirm status of equipment, that safety guards are in place, equipment is fit for operation and required services are available
• collect and position materials according to job and equipment requirements which may require locating datum
• set up, operate and shut down equipment according to workplace procedures to meet job specification
• monitor and adjust process and equipment during operation to stay within specification
• confirm that components meet specification - this may involve the use of measuring instruments
• maintain work area to meet housekeeping standards

Required knowledge includes:

Knowledge of: 

• relevant state OHS legislation, standards and codes of practice relating to work responsibilities
• relevant site operating procedures and practices
• purpose and basic operating principles of lathe and accessory equipment including awareness of equipment operating capacities
• care, maintenance and storage of tool parts and accessories
• scope to adjust machining parameters and related effect on outcome
• the impact of machining parameters and materials used on tool life
• safe work procedures including awareness of health and safety hazards related to the operation of the lathe and related equipment
• housekeeping standards for the work area

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Assessment must be carried out in a manner that recognises the cultural and literacy requirements of the assessee and is appropriate to the work performed.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of ability to:

• identify lathe requirements
• select, fit and use personal protective clothing and/or equipment
• confirm status of equipment
• collect and position materials
• set up, operate and shut down equipment
• monitor and adjust process and equipment during operation

Context of and specific resources for assessment

Assessment must occur in a real or simulated workplace where the assessee has access to:

• Lathe and related equipment
• Relevant measuring instrumentation
• Materials for lathing
• Drawings, templates and specifications as required
• Operating procedures and related advice on equipment/instrumentation operation
• Personal protective clothing and equipment
• Housekeeping standards and procedures

Method of assessment

Other units of competency relevant to the work role should be assessed in conjunction with this unit.

Guidance information for assessment

To ensure consistency in one's performance, competency should be demonstrated on more than one occasion over a period of time in order to cover a variety of circumstances, cases and responsibilities, and where possible, over a number of assessment activities.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. 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) may also be included.

Policies and procedures 

Work is carried out in accordance with company policies and procedures, licensing requirements, manufacturer's recommendations, legislative requirements, codes of practice and industrial awards and agreements.

Codes of practice 

Codes of practice include the Sugar Milling Operations Industry Code of Practice.

Lathe operations 

Work is undertaken to predetermined specifications.

Lathes are not CNC (Computer Numerical Control) machines and may be fitted with three or four jaw chucks.

Typical operations include

• parallel cutting
• parting off
• drilling and knurling.

Machining parameters 

Machining parameters are typically given and include

• speeds
• feeds
• stops
• coolant
• cutting lubricants.

Measuring instrumentation 

Measuring instrumentation may include

• callipers
• dividers
• verniers and
• micrometers
• rulers.

Pre-operational checks 

Pre-operational checks may include

• confirming that safety guards are in place
• equipment is operational
• other pre-start checks as required by workplace procedure.

Basic routine maintenance 

Basic routine maintenance includes cleaning and lubrication.

Teamwork 

Work may require the ability to work within a team environment.
