Mechanism of Unstable Material Removal Modes in Micro Cutting of Silicon Carbide
Micromachines, 2019 This study conducts large-scale molecular dynamics (MD) simulations of micro cutting of single crystal 6H silicon carbide (SiC) with up to 19 million atoms to investigate the mechanism of unstable material removal modes within the transitional range of ...

Simulasi Komputer Untuk Memprediksi Besarnya Daya Pemotongan Pada Proses Cylindrical Turning Berdasarkan Parameter Undeformed Chip Thickness [PDF]
, 2002 In metal cutting using machine tool, the power required to perform machining operation is influenced by cutting parameters. Some of these parameters are feed, depth of cut, cutting speed and metal removal rate. Undeformed chip thickness is the thickness

Cad Based Predictive Models Of The Undeformed Chip Geometry In Drilling
, 2009 Twist drills are geometrical complex tools and thus various researchers have adopted different mathematical and experimental approaches for their simulation. The present paper acknowledges the increasing use of modern CAD systems and using the API (Application Programming Interface) of a CAD system, drilling simulations are carried out.

The Anatomical Record, EarlyView.Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Bubbles dynamics in microchannels: inertial and capillary migration forces
, 2017 This work focuses on the dynamics of a train of unconfined bubbles flowing in microchan- nels. We investigate the transverse position of a train of bubbles, its velocity and the associated pressure drop when flowing in a microchannel depending on the ...
