STUDY OF THE CUT PRODUCTIVITY IN WOOD PINUS ELLIOTTII USING A PORTABLE SAWMILL PROTOTYPE. Maderas, Cienc. tecnol. [online]. 2010, vol.12, n.1, pp.43-52. ISSN 0718-221X.  http://dx.doi.org/10.4067/S0718-221X2010000100005.

Sawmilling can add value to wood produced in small rural properties. The aim of this paper was to evaluate the quality of Pinus elliottii lumber saw-milled using the first prototype of portable sawmill made by the partnership among a research institution and industrial corporation. During saw-milling there were evaluated the volume yield, maximum productivity, cutting deviation, and feed speed of the prototype. The tests performed revealed that the prototype needs some mechanical modifications in order to decrease cutting deviation of the last saw-milled boards from the log. However, the volume yield was greater than 71%, the feed speed of the prototype were between 0.94 and 1.82 m/s, and the maximum productivity was 2.17 m3/h, these values are equal or better than those reached by similar imported equipments. The maximum cutting deviation was below the level allowed by the Brazilian standard NBR PB 1560.
