Avaliação de indicadores técnicos de uma serraria no município de Xinguara-PA

Abstract

The objective of this study was to evaluate the technical indicators of a sawmill in the town of Xinguara - Para. In bandsaw was performed regression analysis in order to verify the correlation between the dependent variable (time) and the independent variable (diameter) . the primary and secondary machines, used during the sawing in the sawmill production line were evaluated. the service of the sawmill was accompanied by the end of the work shift, timing all the activities developed by the team recording the execution time of each element (log, board and board) of the operating cycle processing individually. Determined that the minimum number of operating cycles, mechanical availability, operational efficiency and effective productivity. The number of performed operating cycles was sufficient for sampling. The mechanical availability of bandsaw was on average 70.22%. In the circular saw and destopadeira pendulous mechanical availability was on average of 73.71% and 51.29%. In bandsaw it was observed that the variables are correlated, as it increases the diameter, requires more effective time for sawing the log in the vertical band saw. It was concluded that mechanical availability, operational efficiency and effective productivity were relatively good, showing that the sawmill has a good operational performance.
