A feedback control technique regulated tool spindle speed while cutting to maximize tool performance. Machining of melamine-coated particleboard was conducted on a computer numerical control router with tungsten carbide inserts. Four cutting scenarios were applied: constant low spindle speed, constant high spindle speed, step function cutting and cutting using feedback control technique. After each test, panel chipping and tool wear were assessed to determine the effect of varying the spindle speed on tool wear and panel chipping. The findings indicated that although tool wear increased, panel chipping decreased when the spindle speed remained continuously high. A constant low spindle speed increased panel chipping and decreased tool wear. Raising the spindle speed in the step function setting reduced tool wear and panel chipping, but it was not apparent when these speed adjustments should be made. The feedback control technique greatly extended the tool life, improving surface quality. The study contributes significantly to wood-based machining procedures and greatly impacts the woodworking sector. The advantages of improved tool life and increased productivity justify the need for more research in this area.}, journal={WOOD MATERIAL SCIENCE & ENGINEERING}, author={Gisip, Judith and Lemaster, Richard and Saloni, Daniel}, year={2024}, month={Dec} }

The objective was to determine the sensitivity of an acousto-ultrasonic-based technique to varying braze conditions of carbide teeth. This preliminary research developed a quick NDE technique to test not only the quality of brazed joints during manufacture, but also to inspect the carbide for micro-cracks that may have been introduced by stresses during the brazing process. The test system used an electric spark against the sawblade teeth or plate to initiate a stress wave in the sawblade which was received by an acoustic emission sensor coupled to the sawblade with a fluid couplant. A reading was taken through the saw tip and adjacent to the saw tip on the saw shoulder. An energy reading of each of the signals was obtained. A ratio was then taken of the two energy values. This gave a "self-calibrating" feature taking into account various slots and holes in the blade which could affect the waveform. This system was able to detect braze joints that had too much or too little heat applied during the brazing process, as well as no flux or twisted teeth. Future work will be conducted on saws of various sizes and designs as well as different grades of carbide tips.}, number={3}, journal={WOOD MATERIAL SCIENCE & ENGINEERING}, author={Lemaster, Richard L. and Schultz, John}, year={2016}, pages={164–169} }

The dependence of the measured values of air permeation rate on the pressure difference was described using linear equations within a regression analysis. The group of OSB/3 samples exhibited a lower resistance to air permeation than OSB/4 (about 61% for both thicknesses).

The main advantages are related to handling improvements of residual wood and energy generation opportunities when compared with wood chips from other forms of wood residues. The objective of this study was to evaluate the energy balance for production of briquettes from wood residues. This research involved determining the energy consumption required to perform the main manufacturing operations to produce wood briquettes: size reduction, drying, and densification of wood. The amount of energy that can be obtained from the combustion of wood briquettes was also measured. The effects of several factors such as wood species, material dimensions, and raw material moisture content on the energy requirements for manufacturing briquettes were studied. Four densification strategies were evaluated from an energy consumption standpoint: single size reduction (shredding) of dry lumber and wood chip densification; single size reduction (shredding) of wet lumber, drying, and wood chip densification; double size reduction (shredding and hammermilling) of dry lumber and wood particle densification; and primary size reduction (shredding) of wet lumber, wood chip drying, secondary size reduction of wood chips, and wood particle densification. At most 8 percent of total energy available from combustion of briquettes is required to produce briquettes. Moreover, drying wet wood residues consumes about 80 percent of the energy used in producing the briquettes. This study shows that manufacturing briquettes from wood residues is feasible from an energy consumption perspective.}, number={4}, journal={FOREST PRODUCTS JOURNAL}, author={Arrieche, Rafael and Saloni, Daniel and Dyk, Herman and Lemaster, Richard L.}, year={2011}, pages={302–309} }

Thus, the volume of material produced and used is steadily increasing while the range of applications keeps expanding. So far, attention has been paid mainly to primary production processes of wood fiber–plastic materials, while secondary manufacturing processes have attracted less attention. However, with the broadening applications of such materials and their increasing use, secondary manufacturing processes for wood fiber–plastic materials are gaining importance. This study investigated the performance of five commercially available wood fiber–plastic composite materials and solid wood (eastern white pine) with respect to tool wear and resulting material surface roughness. Large performance differences between different wood fiber–plastic composite materials and between solid wood and wood fiber–plastic composite materials with respect to tool wear were found. Solid wood did wear the exchangeable tungsten carbide knives with a standard cobalt binder and ultrafine carbide grain knives used for the tests 12 to 42 times less than the wood fiber–plastic composite materials. However, some wood fiber–plastic materials were found to have a smoother surface than solid wood after 38.2 m of cutting. As this research showed, different wood fiber–plastic composite formulations behave differently when subjected to secondary manufacturing processes, and more research is needed to better understand the underlying causes for those observations.}, number={2}, journal={FOREST PRODUCTS JOURNAL}, author={Saloni, Daniel and Buehlmann, Urs and Lemaster, Richard L.}, year={2011}, pages={149–154} }

Thermography has been proven to detect knots in lumber, but the use of active thermography has not been investigated in terms of detecting dents, holes, and gouges. This research focused on four heating techniques, i.e. defect side heating, back side heating, forced air heating, and pulsed thermography, to detect dents, holes, gouges, and knots. All four heating methods proved successful for at least two defect types.

Abrasive machining is one of the most important of these processes and therefore merits special attention and study. The objective of this work was to evaluate and demonstrate a process monitoring system for use in the abrasive machining of wood and wood based products. The system developed increases the life of the belt by detecting (using process monitoring sensors) and removing (by cleaning) the abrasive loading during the machining process. This study focused on abrasive belt machining processes and included substantial background work, which provided a solid base for understanding the behavior of the abrasive, and the different ways that the abrasive machining process can be monitored. In addition, the background research showed that abrasive belts can effectively be cleaned by the appropriate cleaning technique. The process monitoring system developed included acoustic emission sensors which tended to be sensitive to belt wear, as well as platen vibration, but not loading, and optical sensors which were sensitive to abrasive loading.}, number={11}, journal={SENSORS}, author={Saloni, Daniel E. and Lemaster, Richard L. and Jackson, Steven D.}, year={2010}, month={Nov}, pages={10401–10412} }

This research investigates the use of both frequency domain analysis as well as the more advanced joint time frequency analysis (JTFA). The disadvantages of traditional frequency analysis as well as the potential of the JTFA are illustrated. Sample surface profiles from actual machining defects were analyzed using traditional frequency analysis. A surface with multiple machining defects was analyzed with both traditional frequency analysis and JTFA (harmonic wavelet). Although the analysis was empirical in nature, the results show that the harmonic wavelet transform is able to detect both stationary and non-stationary surface irregularities as well as pulses (localized defects).}, number={4}, journal={SCANNING}, author={Lemaster, Richard L.}, year={2010}, pages={224–232} }

Grazing incidence X-ray diffraction was used to identify a boron carbide phase, which exhibited weak peaks. The presence of particulates in the size range of 50 nm–3 µm embedded in an amorphous matrix was observed by scanning electron microscopy. Raman spectroscopy indicated that as methane partial pressure was increased during deposition, the amount of disorder with the boron carbide structure also increased. Also, the nanoindentation hardness decreased, while the coefficient of friction and scratch adhesion strength increased. These effects are attributed to an increase in amorphous phase/disorder in the films. Wear tests conducted by machining particleboard using boron carbide coated WC–Co tools in the absence of methane showed the same wear rate as tools coated under higher methane pressures.}, number={20-21}, journal={SURFACE & COATINGS TECHNOLOGY}, author={Jagannadham, K. and Watkins, T.
