Silva Fennica vol. 52 no. 3 article id 9947. 22 p. https:// doi.org/10.14214/sf.9947 Highlights • Use of harvester on-board computer bucking optimization remains highly under-utilized in German forestry. • Revenue per tree and harvesting productivity were both statistically higher with automatic bucking as compared to quality bucking during a thinning operation in a spruce dominated stand. Abstract Tree bucking, defined as the process in which a stem is segmented into shorter logs of varying lengths, has a significant effect on the value adding potential of a forest enterprise. Because of its importance in terms of correct product and length combinations, improper bucking can lead to financial losses. In this study, two treatments (OFF: quality bucking performed by the opera- tor while using hot keys and ON: automatic bucking using the optimized suggestions from the harvester on-board computer; OBC) were tested in a Norway spruce (Picea abies [L.] Karst.) dominated stand located in Germany. Both treatments had the aim to maximize the value of a stem.

A 3D log sawing optimization system was developed to perform log generation, opening face determination, sawing simulation, and lumber grading using 3D modeling techniques. Heuristic and dynamic programming algorithms were used to determine opening face and grade sawing optimization. Positions and shapes of internal log defects were predicted using a model developed by the USDA Forest Service. Lumber grading procedures were based on National Hardwood Lumber Association rules. The system was validated through comparisons with sawmill lumber values. External characteristics of logs, including length, large- end and small-end diameters, diameters at each foot, and defects were collected from five local sawmills in central Appalachia. Results indicated that hardwood sawmills have the potential to increase lumber value through optimal opening face and sawing optimizations. With these optimizations, average lumber value recovery could be increased by 10.01% using the heuristic algorithm or 14.21% using the dynamic program- ming algorithm. Lumber grade was improved significantly by using the optimal algorithms. For example, recovery of select or higher grade lumber increased 16-30%. This optimization system would help small sawmill operators improve their processing performance and improve industry competitiveness.

  • Intensive Hardwood Log Bucker Training Using HW Buck Dramatically Improves Value Recovery
    Intensive Hardwood Log Bucker Training using HW Buck Dramatically Improves Value Recovery James B. Pickens, School of Forest Resources and Environmental Science, Michigan Technological University, Houghton, MI, [email protected] Aaron Everett, Black Hills Forest Resource Association, Rapid City, SD Scott Noble, Noble Forestry Consulting, Chassell, MI John Baumgras (retired), Northeastern Forest Experiment Station, USDA Forest Service, Princeton, WV Philip Araman, Southern Forest Experiment Station, USDA Forest Service, Blacksburg, VA Conrad Waniger, forest harvesting contractor, Shawano, WI Al Steele, Wood Education and Resource Center (WERC) of the USDA Forest Service, Princeton, WV ABSTRACT It has long been recognized that inappropriate placement of crosscuts when manufacturing hardwood logs from harvested stems (log bucking) reduces the value of logs produced. Recent studies have estimated losses in the range from 28% to 38% in the lake states region. It has not, however, been clear how to correct the problem. Efforts to improve value recovery have followed two general approaches: using technological methods to actually optimize the bucking of each log or having recognized experts train log buckers to make better bucking decisions. This article describes the state-of-the-art for optimizing the bucking of hardwood logs, and documents a log bucker training approach that resulted in improved value recovery of over 30%. Field buckers underwent an intensive training process to help them make better bucking decisions. This training integrated use of HW Buck, a computerized tool to optimize the choice of bucking cuts for hardwood logs, with other more traditional training approaches. Sample hardwood stems were felled and entered into the HW Buck software to determine the individual bucking options that maximized the value of the resulting logs.

  • AP-42, CH 10.5: Plywood Manufacturing
    10.5 Plywood Manufacturing 10.5.1 General Plywood is a building material consisting of veneers (thin wood layers or plies) bonded with an adhesive. There are two types of plywood: softwood plywood and hardwood plywood. Softwoods generally correspond to coniferous species. The most commonly used softwoods for manufacturing plywood are firs and pines. Hardwoods generally correspond to deciduous species. For hardwood plywood, commonly used wood species include oak, poplar, maple, cherry, and larch. Softwood plywood is manufactured by gluing several layers of dry softwood veneers together with an adhesive. Softwood plywood is used for wall siding, sheathing, roof decking, concrete formboards, floors, and containers. Softwood plywood is classified under Standard Industrial Classification (SIC) code 2436, and North American Industrial Classification System (NAICS) code 321212 for “Softwood Plywood and Veneer”. Hardwood plywood is made of hardwood veneers bonded with an adhesive. The outer layers (face and back) surround a core which is usually lumber, veneer, particleboard, or medium density fiberboard. Hardwood plywood may be pressed into panels or plywood components (e.g., curved hardwood plywood, seat backs, chair arms, etc.). Hardwood plywood is used for interior applications such as furniture, cabinets, architectural millwork, paneling, flooring, store fixtures, and doors. Hardwood plywood is classified under SIC code 2435 and NAICS code 321211, for “Hardwood Plywood and Veneer”. Softwood plywood plants typically produce softwood veneers and softwood plywood on the same plant site. However, most hardwood plywood and veneer plants either produce hardwood plywood or hardwood veneer. Hardwood veneer plants cut and dry hardwood veneers. Hardwood plywood plants typically purchase hardwood veneers and press the veneers onto a purchased core material.

ABSTRACT. The study focused on the frequency of applying a manual tree-stem bucking to logs in coniferous forests of Finland. The aim of the study was to clarify harvesting conditions where manual log bucking is utilized most and the effects of the utilization of manual bucking on the log bucking outcome. In addition to the stm Big Data of harvesters, in order to investigate the consequences of manual log bucking, data from the enterprise resource production (ERP) systems of wood procurement organization and sawmills was collected, as well as harvester operators were interviewed. The study results illustrated that the share of manual bucking of Norway spruce (Picea abies L. Karst.) logs was, on average, 46% and with Scots pine (Pinus sylvestris L.) logs 67%. The operators used manual bucking more frequently in thinning stands with small-sized and defected log stems. When the utilization degree of manual log bucking was high, the utilization of log sections with spruce and pine log stems was lower, logs were shorter and the volume of logs was smaller.

  • HW Buck for Windows: the Optimal Hardwood Log Bucking Decision Simulator with Expanded Capabilities
    HW Buck for Windows: The Optimal Hardwood Log Bucking Decision Simulator with Expanded Capabilities Scott Noble, Noble Forestry Consulting, Chassell, Michigan Blair Orr, School of Forest Resources and Environmental Science, Michigan Technological University, Houghton, MI James B. Pickens, , School of Forest Resources and Environmental Science, Michigan Technological University, Houghton, MI, [email protected] Philip Araman, Southern Forest Experiment Station, USDA Forest Service, Blacksburg, VA John Baumgras (retired), Northeastern Forest Experiment Station, USDA Forest Service, Princeton, WV Al Steele, Wood Education Resource Center (WERC) of the USDA Forest Service, Princeton, WV ABSTRACT It has long been recognized that inappropriate placement of crosscuts when manufacturing hardwood logs from harvested stems (log bucking) reduces the value of logs produced. Recent studies have estimated losses in the range from 28% to 38% in the lake states region. These estimates were developed by evaluating the bucking cuts chosen by harvesting crews and comparing them to the optimal bucking pattern chosen by HW Buck, a computerize tool to optimize the choice of bucking cuts for hardwood logs. These losses are not surprising because the hardwood log bucking problem is very complicated. Hardwood log grading and scaling rules are complex. Furthermore, hardwood stems tend to be less straight than softwoods, and have grade and scale reducing defects scattered along the entire stem. The original DOS version of HW Buck, which was recognized by the NHLA Hardwood Research Award in 1996, was very useful. However, it was written to run on the DOS operating system, which limits its current utility. The DOS version also did not have the flexibility required to accurately depict the complexity of hardwood markets, which vary by species, region, and even organization.
