Analyses of Shear Angle in Orthogonal Cutting of Pine Wood

The determination of energy effects for wood machining processes, such as cutting power and forces, is very useful in designing manufacture process wooden products. A more accurate prediction forces requires a correct the shear angle value, which can be determined using various models. In this article, values an orthogonal linear pine are determined. analysed was represented by two groups samples with different moisture content levels, 12 % 20 %. Three models were used to determine values: Merchant model, based on rake friction, model chip compression ratios Atkins material properties (elements fracture mechanics). obtained have been comparison. Results showed that shearing angles from turned out higher than equation. are, expected, lower those model. Furthermore,
