“…Rinn et al found that the feed resistance of the drill needle does not contain additional important information. Therefore, most scholars have studied the correlation between drill needle rotation resistance and wood density [37][38][39][40]. In order to study the correlation between the feed resistance of drilling needles and wood density, the paper designed a micro drilling instrument that can simultaneously measure the rotation resistance and feed resistance of drilling needles.…”

“…A significant amount of research has been done to explore the use of the micro drill resistance instrument for various application such as tree-ring analysis [2,[5][6][7], tree age [3,8], wood density measurement [9][10][11][12][13], tree decay detection [14]and structural timber condition assessment [15]. Rinn et al demonstrated that Resistograph profiles of coniferous and deciduous wood can reveal density variations inside tree rings caused by earlywood and latewood.…”

To improve the measurement accuracy of wood density and study the linear correlation between the drill feed resistance and wood density, a new micro drill instrument that can can simultaneously measure the rotation resistance and feed resistance of the drill needle was designed. The test wood samples included hardwood, softwood and conifer. The absolute dry density of each wood sample was measured. The drill resistance data was tested by using self-developed micro drill instrument and Resistogaph 650-SC. 4 linear models between drill resistance and the absolute dry density of wood . The results showed that: the statistical indicators of each model of the self-made micro drill resistance in-strument were better than the corresponding indicators of Resistogaph 650-SC; the coefficient of determination of the linear regression model between the feed resistance of the self-made micro drill resistance instrument and the absolute dry density of wood was 0.946; the statistical indicators of model including rotation resistance and feed resistance, were better than those of the model only including rotation resistance. Therefor, the design proposed in the article is reasonable, and increasing the feed resistance can improve the measurement accuracy of the micro drill resistance instrument for measuring wood density.

“…Assessing of wood basic density in a standing tree would be helpful for selection activity in the tree improvement program and for operational plantation management before they are harvested. The use of the drilling resistance method, which uses a thin needle to penetrate the wood of standing trees (da Silva et al 2020;Balasso et al 2021;Li et al 2022), can be an opportunity to assess the wood basic density (Gao et al 2017;Fundova et al 2018;Nickolas et al 2020). The drilling resistance value is a unit that serves as an indicator of the basic wood density (Isik and Li 2003;Bouffier et al 2008;Karlinasari et al 2017;Gendvilas et al 2021;Vlad et al 2022).…”

Abstract. Singh KP, Siregar IZ, Abad JIM, Karlinasari L. 2022. Non-destructive modeling using a drilling resistance tool to predict wood basic density of standing trees in a eucalypts plantation in North Sumatra, Indonesia. Biodiversitas 23: 6218-6226. Eucalypts are globally selected as the main tree species for pulp and paper industries owing to their good potential growth and wood traits. Wood basic density, which is related to wood biomass yield, is one of the most important wood traits for pulp production and has become a focus in the tree improvement program. Evaluation of this trait in the field is needed to efficiently develop tree improvement programs. The aims of this study were to determine the distribution of basic density in the vertical direction of standing trees, including Eucalyptus grandis, Eucalyptus urophylla, and E. grandis × E. urophylla hybrid (commonly called “urograndis”), and to develop a model for predicting wood basic density using micro-drilling resistance tools of ResistographÒ. The results showed that basic density traits varied within individual trees and within and between species. Average whole tree basic wood densities of 379.9 kg/m3, 400.5 kg/m3, and 440.6 kg/m3 were found for E. grandis, hybrid urograndis, and E. urophylla at 44 months old, respectively. The model developed had a good correlation for predicting wood basic density at 1.3 m height and whole tree basic density, with the R2 for model calibration ranging from 0.52 to 0.76 for 1.3 m wood basic density prediction and from 0.62 to 0.79 for whole tree wood basic density. This study found that the three species of eucalyptus could be used to create a combined model for predicting wood basic density that could be used for each individual species. The model for single and multiple species had a good validation with R2 from 0.51 to 0.72.

“…The energy consumption is correlated with the physical, mechanical, and technological properties of the drilled wood. Drilling resistance measurements were used to predict the density and elastomechanical properties of wood and wood-based materials (Rinn et al 1996;Faggiano et al 2011;Zhang et al 2011;Kloiber et al 2014;Oliveira et al 2017;Downes et al 2018;Sharapov et al 2019;Nickolas et al 2020).…”

Improving the properties of laminated veneer lumber (LVL) through wood modification expands its usage as building material, especially for outdoor applications. The outdoor performance of LVL products needs to be tested against different biotic agents, and methods are needed for testing and evaluating their effect on the structural integrity of LVL. In this study, drilling resistance (DR) measurements were used to quantify the effect of fungal decay in phenol-formaldehyde (PF) resin treated European beech (Fagus sylvatica L.) LVL caused by white rot fungi. Material specific peculiarities and their effect on the evaluation method were studied such as the effect of drill bit blunting, moisture content (MC), drilling direction and PF resin content on the DR of PF-modified LVL. The drilling direction in relation to veneer and glue layers had a significant effect on DR and feeding resistance (FR). The PF resin treatment increased the DR. Feeding resistance was found more sensitive to the blunting of the drill bit than DR. The effect of MC on DR and FR was found to be insignificant. The effect of PF resin content on the prediction of mass loss (ML) by DR became prominent only for ML by white rot decay below 10 %. Correlations between DR, ML due to fungal decay and weight percent gain were established and described with a two-factor regression model. The drill bit feed rate of 0.5 m min −1 and the rotational frequency of 3500 min −1 as well as the transversal drilling in relation to the veneer (glue) layers were recommended for the assessment of beech LVL treated with PF resin. The DR measurements showed high potential as a fast standard evaluation method for decay and strength loss of LVL products.
