European Beech Log Sawing Using the Small-Capacity Band Saw: A Case Study on Time Consumption, Productivity and Recovery Rate

In rural, isolated areas, sawmills are often equipped with one or more small-capacity hand-fed band saws. Even in this situation, the productivity of saw must be viewed through factors that influence it, namely characteristics logs and optimization stages activities carried out. Therefore, time consumption, structure working recovery rate sawing into lumber provide important information for users. The operation a work team made up an operator assistant was divided six stages. pattern used involves log to approximately half diameter, then rolling 180° continuing sawing, aiming obtain thickness 40 50 mm from central part log. 2.45 m3·h−1, 70.84% real-use coefficient 0.37. Research has highlighted positive correlation between middle diameter (R2 = 0.84). feeding speed also determined along quality cuts, which expressed by uniformity presence cutting teeth traces on newly created surfaces.
