Productivity of sawing the machiche wood (Lonchocarpus castilloi Standl), in Tres Garantías, Quintana roo, Mexico

Yields and sawing time were determined in order to know the sawmilling productivity of Lonchocarpuscastilloi Standl. (machiche). The yields were determined by relating the volume of logs andsawn timber volume of 815 logs. Milling times were determined using the total time method in the mainsaw. Eigh...

description Yields and sawing time were determined in order to know the sawmilling productivity of Lonchocarpuscastilloi Standl. (machiche). The yields were determined by relating the volume of logs andsawn timber volume of 815 logs. Milling times were determined using the total time method in the mainsaw. Eighty percent of logs recorded diameters from 30 cm to 40 cm, and 94% of them had lengthsfrom 2 m to 3 m. The total volume processed was 194,6 m3 round wood without-bark (rwwb), that generateda volume of 80,8 m3 of sawn lumber. This indicates that to produce one cubic meter of lumber,2,45 m3 of machiche are required. The actual global sawmill coefficient was 41,3%, the coefficient forgrades of boards was 43,1% in boards of sapwood, 34,1% in boards of heartwood, and 22,8% inboards with rejection grade. The productive time was 68%, the non-productive time 19%, and theleisure time 13%. The productivity was at 0,57 m3/ hour. The productivity indicators identified, provideuseful information for the efficient administration for sawmill of the ejido.

Se determinaron rendimientos y tiempos de aserrado, con el propósito de conocer la productividaddel aserrío de Lonchocarpus castilloi Standl. (machiche). El rendimiento se determinó al relacionarel volumen de madera en rollo y el volumen de madera aserrada de 815 trozas. Se determinarontiempos de asierre, empleando el método del tiempo total en la sierra principal. En 80% de lastrozas se registraron diámetros de 30 cm a 40 cm y en 94%, longitudes de 2 m a 3 m. El volumen totalfue de 194,6 m3 rollo fuste sin corteza (rfsc), que al procesarse generaron un volumen de 80,8 m3aserrados. Esto indica que para producir un metro cúbico de madera aserrada se requieren 2,45 m3rfsc de machiche. El coeficiente de aserrío real global fue 41,3%; el coeficiente por clases de tablasfue 43,1% en tablas de albura, 34,1% en tablas de duramen y 22,8 % en tablas de rechazo. El tiempotrabajado productivo fue de 68%, el tiempo trabajado no productivo fue de 19% y el tiempo no trabajadojustificado fue de 13%. La productividad se ubicó en 0,57 m3/hora. Los indicadores de productividaddeterminados proveen información útil para la administración eficiente del aserradero ejidal.
