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.

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.

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 ...

Analysis on Wood Quality, Geometry Factor, and Their Effects on Lathe Check of Samama (Anthocephalus macrophyllus) Veneer

Journal of the Korean Wood Science and Technology, 2016
Relatively little information is available regarding the correlation between wood and veneer quality, especially for Samama wood, an endemic wood species in eastern Indonesia. This study addresses the quality of 8 years old Samama wood and its effect on the veneer quality.

U-NET-based deep learning for automated detection of lathe checks in homogeneous wood veneers

European Journal of Wood and Wood Products
Abstract 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.

Systematics for checking geometric errors in CNC lathes [PDF]

Journal of Physics: Conference Series, 2015
Non-idealities presented in machine tools compromise directly both the geometry and the dimensions of machined parts, generating distortions in the project. Given the competitive scenario among different companies, it is necessary to have knowledge of the geometric behavior of these machines in order to be able to establish their processing capability,
