Influence of Varying Energy Consumption With Different Grain Orientation

Popis výsledku v původním jazyce

Due to the energy consumption during machining, it is important to know cutting resistance, which is a very significant property of the material machined. In the conventional methods, energetic effects (cutting forces, cutting power and cutting resistance) 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 many factors. This paper presents new calculating model using the application of fracture mechanics. New model is based on the application of the Ernst-Merchant theory in the conditions of circular-saw blade cutting. It includes the prediction of the shear plane angle, fracture toughness, shear yield stress, coefficient of friction and shear strain along the shear plane. It provides a possibility of modelling energetic effects of the sawing process even for small values of the chip thickness.
