The Wood Working Industry

The Commercial Importance of Wood- used to make: Furniture Cabinet making Construction Wall Paneling Flooring Cabinets Doors Trim Paper Cardboard Engineered wood Rayon – synthetic fiber used in clothes! Photographic film and plastics

Harvesting and Processing Wood Selective cutting Selecting certain trees to cut down Clear cutting Cutting an entire area of trees down (leaving nothing) Natural Regeneration remaining trees from selective cutting will drop seeds and regenerate the forest

Clear selective

Processing lumber Barking- bark is removed Cut with large band saw into planks Trimmed to various sizes Graded and sorted Wood is dried by air and kiln Turned into siding, paneling and specialty products Bundled and stored

Classes of Wood Hardwood – cut from deciduous trees Trees that shed their leaves Walnut, maple, birch, cherry, and oak

Softwood – cut from coniferous trees Trees that have cones Pine, fir, cedar, and redwood

Other materials: Panel stock- wood formed into panels or sheets Plywood- gluing thin layers of wood together Molding- narrow strip of wood used for decoration or practical uses

Common wood defects Knot- dark, round spot where branch had formed Split- large crack Warp- not straight true planed wood

Problem Solving - Design Loop

Step 1- state the problem clearly Step 2- collect information Step 3- develop solutions Step 4- select the best solution Step 5- implement the solution (try it) Step 6- evaluate the solution

Technology CNC – Computer-numerical control CAD – Computer-aided drafting CAM – Computer-aided manufacturing CIM – Computer-integrated manufacturing Robots Lasers

Craftspeople Carpenter Precision Woodworking or Cabinetmaker Millwright

Technicians Drafter- finishes plans begun by an architect or designer Education: CAD training after highschool Forestry Technician Engineering Technician

Professionals Forester Architect Furniture designer Teacher

3 characteristics employees look for: Positive attitude Willingness to learn Ability to follow directions and obey rules Ability to solve problems Ability to accept criticism Cooperation Dependability Honesty loyalty
