Factors Affecting Plunge Grinding Force [PDF]

open access: yes, 1980
Grinding force has a close relation to grinding inputs such as grinding wheel, work material, interference condition, grinding speed, grinding fluid and machine condition, and therefore varies widely with grinding inputs.

Determination of micro-scale plastic strain caused by orthogonal cutting [PDF]

open access: yes, 2008
An electron beam lithography technique has been used to produce microgrids in order to measure local plastic strains, induced during an orthogonal cutting process, at the microscopic scale in the shear zone and under the machined surface. Microgrids with

Scaling properties of a low-actuation pressure microfluidic valve [PDF]

open access: yes, 2004
Using basic physical arguments, we present a design and method for the fabrication of microfluidic valves using multilayer soft lithography. These on-off valves have extremely low actuation pressures and can be used to fabricate active functions, such as

Simulation of a finishing operation : milling of a turbine blade and influence of damping [PDF]

open access: yes, 2012
Milling is used to create very complex geometries and thin parts, such as turbine blades. Irreversible geometric defects may appear during finishing operations when a high surface quality is expected.

An investigation on the mechanics of nanometric cutting and the development of its test-bed [PDF]

open access: yes, 2003
The mechanics of machining at a very small depth of cut (100 nm or less) is not well understood. The chip formation physics, cutting forces generation, resulting temperatures and the size effects significantly affect the efficiency of the process and ...
