Online control of wood peeling process: Acoustical and vibratory measurements of lathe checks frequency [PDF]
Annals of Forest Science, 2007 In the course of most wood machining processes, operators are usually able to detect various problems simply by hearing the sound emitted by the process. This is especially true for wood peeling. Lathe checks formation has been identified as one of the typical situations that an experimented peeler can detect.

Wood peeling process monitoring: a comparison of signal processing methods to estimate veneer average lathe check frequency [PDF]
European Journal of Wood and Wood Products, 2011 Experienced peeling operators are able to adjust the settings of their device by hearing the sound coming from the process. Based on this idea, a research program was undertaken to evaluate the possibility of using acoustic or vibration measurements supplying a support decision system to assist untrained operators.

U-NET-based deep learning for automated detection of lathe checks in homogeneous wood veneers [PDF]
European Journal of Wood and Wood ProductsAbstract Automated detection of lathe checks in wood veneers presents significant challenges due to their variability and the natural properties of wood. This study explores the use of two convolutional neural networks (U-Net architecture) to enhance the precision and efficiency of lathe checks detection in poplar veneers.

Physical properties and bonding quality of laminated veneer lumber produced with veneers peeled from small-diameter rubberwood logs [PDF]
Royal Society Open Science, 2019 The peeling of small-diameter rubberwood logs from the current short-rotation practices undoubtedly will produce lower grade veneers compared to the veneers from conventional planting rotation.

A Method of Lathe Checks Measurement; SMOF device and its software [PDF]
European Journal of Wood and Wood Products, 2009 <p>In the present paper, a novel method for veneer checks measurement and description based on digital image analysis is evaluated. According to this method, the camera is located sideways to the veneer allowing for viewing the checks geometry in the cross-section of the veneer.

Lathe check development and properties: effect of log soaking temperature, compression rate, cutting radius and cutting speed during peeling process of European beech (Fagus sylvatica L.) veneer [PDF]
European Journal of Wood and Wood Products, 2018 The depth of lathe checks and integrity of veneer have been shown to be critical factors affecting the bonding process but also affecting the mechanical properties of veneer-based products. This study shows how beech (Fagus sylvatica L.) veneer lathe checks interval and depths are affected by soaking temperature, compression rate, cutting radius and ...
