Application
This unit of competency describes the outcomes required to widen then press into shape, through a cold forming process, the cutting points of saw teeth to create a block that has the required hook, back, tangential and radial clearance angles for efficient saw operation. Work is completed in a wood products factory setting.
The unit applies to Sawdoctor, Saw Repairer.
No licensing, legislative, regulatory, or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions. |
1. Set up equipment | 1.1 Review work order and where required check with appropriate personnel. 1.2 Identify required swage shape and thickness from existing saws and relevant records. 1.3 Select appropriate personal protective and other equipment and check for operational effectiveness. 1.4 Set up saw, swage and shaping equipment to meet production requirements. 1.5 Check die or swage clamp or vice shape against required shape, clearances and kerf, and change as required. 1.6 Secure saw in a swage clamp or vice or swager with teeth aligned to swager or vice shape. 1.7 Apply anti-scuffing paste to areas of saw for swaging. |
2. Swage teeth | 2.1 Use equipment in line with organisational safety procedures, manufacturer’s instructions and environmental protection practices. 2.2 Complete trial swage, check and adjust swaging setup. 2.3 Accept or reject trialled material and dispose of in line with environmental protection practices. 2.4 Inspect swage shape and thickness and measure for tangential and radial clearance and kerf. 2.5 Adjust swaging operation to meet production specifications. 2.6 Check dies for wear and adjust to ensure accurate operation. 2.7 Swage remaining teeth in line with production and manufacturer specifications. |
3. Shape teeth | 3.1 File and shape excess material resulting from swaging process. 3.2 Complete trial shape and check tooth tolerances, adjusting as required. 3.3 Accept or reject trialled material and dispose of in line with environmental protection practices. 3.4 Assess shape and check tooth alignment, adjusting remaining teeth as required. 3.5 Record and report processing problems and equipment faults to appropriate personnel. |
