FEM analysis of ultrasonic-vibration-assisted turning and the vibratory tool

Analysis of ultrasonic assisted machining (UAM) on regenerative chatter in turning

“…Based on the structure of the fixture, two nodes are available for holding the tool. To obtain the mentioned characteristics, the tool was designed and analyzed using finite element modal analysis inspired from the work of Amini et al (2008). After delicate design, the length of the cutting tool was calculated 122 mm, and its cross section was 30 mm × 30 mm.…”

Thermomechanical analysis of multi-bead pulsed laser powder deposition of a nickel-based superalloy

“…The lateral overlap between beads is 25%. Physical and thermomechanical properties of IN738 (Sciti et al, 2001;Aminia et al, 2008;Quested et al, 2009). …”

Micro-cutting of single-crystal metal: Finite-element analysis of deformation and material removal

“…To our knowledge, three main modelling techniques are usually employed to simulate material removal: element deletion [29,38], arbitrary Lagrangian-Eulerian adaptive remeshing (ALE) [18,20,39] and smooth particle hydrodynamics (SPH) [27,40,41]. Our studies indicated that the three modelling techniques produce almost identical results for the cutting forces, however, the element deletion technique was the most computationally efficient [42].…”
