Timber and Woodworking Industry

Studies have shown that there is a potential to increase lumber value by over 20 percent if optimum edging and trimming could be performed in sawmills. Even a small part of this percentage would substantially increase the profit of lumber manufacturers. And this can be achieved by utilizing machine vision systems.

Application of machine vision systems in the timber and woodworking industry has a very short return-on-investment period due to the increase in plant throughput, increase in production yields and reduction of waste that can be achieved.

Machine vision and image processing is relatively new or underused area in the timber and woodworking industry. The amount of manual work in many woodworking techniques can be reduced or even eliminated with image processing applications while at the same time increasing the quality and reducing the time. Quality of the timber is important in order to decide where the timber should be used.

In many sawmills, the board quality is still controlled by a human sorter because the defects can vary in many ways, color, area, shape, amount and the type of defects can be in various forms. It is important for sawmills to deliver right quality of boards to their clients so the sorting is depending on the worker.

Present trends such as increasing labor costs and limited supplies of high quality logs have forced lumber manufacturers to increase their efforts to maximize the utilization of raw material. In order to make money in such a competitive business, sawmills must produce the highest possible grade of lumber from each saw log they process.

Machine Vision systems for wood processing must be able to reliably detect and identify many lumber features such as wane, cracks, splits, holes, decay, knots, wormholes and board dimension.

Board Grader - Automated Vision Inspection for Board Grading

Justification can be based on saving the significant hidden costs of further processing lower grade timber. The Board Grader consistently grades to 90% accuracy or higher. Grade recipes can be changed instantaneously to meet specific customer requirements.

Databasing software captures, records and reports all grading information for mill and log optimization.
