Prediction of Grinding Force by an Electroplated Grinding Wheel with Orderly-Micro-Grooves

open access: yesChinese Journal of Mechanical Engineering, 2023
The ability to predict a grinding force is important to control, monitor, and optimize the grinding process. Few theoretical models were developed to predict grinding forces when a structured wheel was used in a grinding process.

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

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 ...
