Veneer checking is a common enough occurrence in woodworking. It appears as cracks in the veneer and generally following the grain. Their appearance and the variation of their depth and frequencies have tremendous impact on their utilization. Finding a means of identifying and characterizing the veneer checks is an important ongoing challenge. An automated device, named SMOF, was developed in LABOMAP (Arts et Metiers – France) and achieves this task. By using the SMOF device, the lathe checks occurred in veneers of two species: zeen oak (Quercus canariensis Willd.) and afares oak (Quercus afares Pomel) were detected, automatically imaged and then, the depth and intervals of checks measured. The results were described by statistical distributions that exhibited abnormalities, such as skewness and kurtosis, which were assessed by mode analysis. It has been established that hot soaking temperature (from 60°C to 90°C) reduce slightly the cutting forces for both species, no produce significant heart checks within the loose side of veneers. However, low soaking temperature (from 50°C to 65°C) allow avoiding deeper lathe checking, producing shallower ones acceptable for veneer production.

单板检查是木工中经常发生的情况。它表现为饰面板中的裂纹，通常会随纹理而变化。它们的出现以及深度和频率的变化对它们的利用率有巨大影响。寻找一种识别和表征单板检查的方法是一项持续的重要挑战。在法国LABOMAP（Arts et Metiers，法国）开发了一种名为SMOF的自动化设备，可以完成此任务。通过使用SMOF设备，车床检查发生在两种树皮的单板中：泽恩栎木（Quercus canariensis Willd。）和afares栎木（Quercus afares Pomel））被检测到并自动成像，然后测量检查的深度和间隔。结果通过统计分布描述，这些分布表现出异常，例如偏度和峰度，并通过模式分析对其进行了评估。已经确定，热浸泡温度（从60°C到90°C）会略微降低这两种物种的切割力，而不会在单板的松散面产生明显的心脏检查。但是，较低的均热温度（从50°C到65°C）可以避免进行更深的车床检查，从而生产出可用于单板生产的较浅的车床。
