Application
This unit of competency defines the skills and knowledge required to develop and manufacture all types of solid, split and turned wood patterns and wood pattern component parts, including general engineering and master patterns.
Patterns are constructed by laminating timber and timber composites, stave and lag, box or frame construction or any alternative method that minimises timber shrinkage, warp and achieves required. Solid patterns are set up on a regular or irregular joint. Turned patterns are manufactured using tools and machines appropriate for shaping wood.
Where patterns are required to be set up on pattern plates then unit MEM04012 Assemble plated patterns should also be selected.
Where the development and manufacture of marine propellers, conveyor screws and cast gears is required unit MEM04017 Develop and manufacture gear, conveyor screw and propeller patterns should also be selected.
Where the selection and use of precision measurement is required unit MEM12003 Perform precision mechanical measurement should also be selected.
This unit should not be selected when unit MEM18014 Manufacture press tools and gauges has already been selected.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
