CUTTING POWER FORECASTING WHILE WOOD SAWING: FRACTURE MECHANICS APPROACH AND AXELSSON’S MODEL COMPARISON

Abstract

In the classical approach, energetic effects (cutting forces and cutting power) of wood sawing process are generally calculated on the basis of the specific cutting resistance, which is in the case of wood cutting the function of more or less important factors. On the other hand, cutting forces (power) could be considered from a point of view of modern fracture mechanics. Another way is to forecast cutting power consumption on the basis of existing in the literature empirical models. The prognostication of energetic effects has been done for a real sawing pattern applied in a sawmill, in which mainly pine wood is sawn into lumber. The goal of this study was to compare predictions of cutting powers for the circular sawing machine with one circular saw blade with the use of models which base on modern fracture mechanics and a predictive empirical model proposed by Axelssons.
