The effect of ball mill on the morphological and structural features of cellulose has been described by Okajima and coworkers. 20 They treated microcrystalline cellulose derived from cotton linters in a planetary ball mill at 200 rpm for 48 hours in dry and wet conditions with three solvents (water, toluene, 1butanol). They observed that ...

Ti2AlNb has much application potential in the aerospace sector thanks to its outstanding material characteristics. Poor wear resistance, however, blocks its development. This study used LTUAM (longitudinaltorsional ultrasonicassisted milling) to get the surface microtexture of Ti2AlNb in order to address the issue. By comparing traditional milling (CM), the surface microtexture and ...

Deburring and smooth finishing processes for milled workpieces are well known in macro mould and die manufacturing. These processes are not directly transferable to micro parts and must be modified for this purpose. Therefore, deburring and surface conditioning by micro peening and ultrasonic wet peening of structures made by micro milling of quenched and tempered tool steel are investigated ...
