—A three-dimensional (3D) log sawing optimization system was developed to perform 3D log generation, opening face determination, sawing simulation, and lumber grading. Superfi cial characteristics of logs such as length, large-end and small-end diameters, and external defects were collected from local sawmills. Internal log defect positions and shapes were predicted using a USDA Forest Service ...

Hepatic abscesses caused by ingested foreign bodies have been reported in the medical literature but represent very uncommon events. Extra-luminal migration of sawing needles and pins is the most common cause of perforation of the gastrointestinal tract associated with liver infections. Other non-metallic sharp objects such as animal bones and toothpicks have been described but are less frequen...

This report describes the development of a prototype system that is capable of monitoring the deflection of a bandsaw blade during wood sawing process. The deflection is caused by tension loss of the saw blade and leads to downgrading and value loss of timbers. A CCD-type laser triangulation sensor has been proposed to monitor the saw blade deflection. Deflection monitoring has to be done in re...

This paper deals with the measurement and simulation of saw wire temperature during machining a rock sample in vacuum. It is expected for wire-sawing to keep cutting performance by successive supply edges. The vacuum has been investigated lunar planetary explorations. To clarify deterioration due nickel adhesion on rock, rise was investigated. In experiment, reciprocated slider-clank mechanism ...

This study assessed the machining properties of 11-year-old Eucalyptus urophylla × E. grandis, known as urograndis wood, that was infected by stem canker disease, Chrysoporthe deuterocubensis. Instead being discarded directly, aimed to explore possibility trees used in other applications such furniture. Sawing, planing, and boring well surface roughness healthy were evaluated. The samples colle...
