Effect of Gangue Distributions on Cutting Force and Specific Energy in Coal Cutting
Strojniški vestnik – Journal of Mechanical Engineering, 2020 Coal consists of diverse materials, and gangue is one of the most common ones. At present, most mathematical models about cutting force and specific energy in the cutting process have not taken gangue minerals in coal seams into consideration. The gangue distribution function is proposed to simulate situations in which gangue minerals are in different ...

Influence of basic wood density on the specific cutting energy
Research, Society and Development, 2022 The density of the wood influences directly on the quality of the surface, on the resistance to cutting as well as on the energy required for processing. The aim of this study was to obtain the association between specific cutting energies and basic wood densities in peripheral milling with the use of a computer numerical control.
