Set up, program, operate, or tend computerized or manual woodworking machines, such as drill presses, lathes, shapers, routers, sanders, planers, or wood-nailing machines. Examine finished workpieces for smoothness, shape, angle, depth-of-cut, or conformity to specifications and verify dimensions, visually and using hands, rules, calipers, templates, or gauges. Start machines, adjust controls, and make trial cuts to ensure that machinery is operating properly. Monitor operation of machines and make adjustments to correct problems and ensure conformance to specifications. Examine raw woodstock for defects and to ensure conformity to size and other specification standards. Adjust machine tables or cutting devices and set controls on machines to produce specified cuts or operations. Install and adjust blades, cutterheads, boring-bits, or sanding-belts, using hand tools and rules. Change alignment and adjustment of sanding, cutting, or boring machine guides to prevent defects in finished products, using hand tools. Determine product specifications and materials, work methods, and machine setup requirements, according to blueprints, oral or written instructions, drawings, or work orders. Feed stock through feed mechanisms or conveyors into planing, shaping, boring, mortising, or sanding machines to produce desired components.
