Recent developments in grinding have opened up new avenues for finishingof hard and brittle materials with Nano-surface finish, high tolerance and accuracy.Grinding with super abrasive diamond wheels is an excellent way to produce ultraprecision surface finish. However, super abrasive diamond grits need higher bondingstrength while grinding, which metal-bonded grinding wheels ca...

A on-line monitoring new method for grinding quality is presented based on theory analysis and test study, which collects the information of grinding quality from the AE signals produced by friction and grinding process to realize the on-line intelligent detection and prediction of grinding quality by A wavelet neural network & Fuzzy BP algorithm based network. The reliability and feasibility o...

The majority of semiconductor devices are built on silicon wafers. Manufacturing of high quality silicon wafers involves several machining processes including grinding. This review paper discusses historical perspectives on grinding of silicon wafers, impacts of wafer size progression on applications of grinding in silicon wafer manufacturing, and interrelationships between grinding and two oth...

Surface roughness is a variable often used to describe the quality of ground surfaces as well as to evaluate the competitiveness of the overall grinding system. The subject of this paper is a grinding process performed on P20 tool steel by changing the grinding conditions, including the depth of cut, the grinding passes, the type of wheel, and the cutting fluid supply in the experiment. The mai...

The quality and economy of grinding depend on proper selection of grinding conditions for the materials to be ground. In order to evaluate the effect of heavy-duty grinding, a new performance index, which includes specific material removal rate, size accuracy, and grinding forces, was proposed. Robust design of experiment, including orthogonal arrays, the signal-to-noise ratio (SNR) method, and...

A simple and effective solution to the robot grinding problem is introduced, which significantly reduces vibrations during grinding without additional actuators or active control. The objective is to determine the optimal compliance design for grinding robot tool holders. Specifically, the tool holder design should improve accuracy and productivity while protecting the robot arm from the large ...

The formation of diastereomeric cocrystals of malic acid and tartaric acid was investigated by liquid-assisted grinding in the solid state. We demonstrate that racemic malic acid can be converted into two distinct diastereomeric cocrystal phases by grinding with a single enantiomer of tartaric acid.

In this investigation, experiments were carried out to understand the influence of various grinding parameters like wheel speed, workspeed and depth of cut on the grinding temperature at the surface of the Al-SiCP composite workpiece with different grinding wheels. The temperature distribution within the workpiece was studied by simulating the grinding process and using finite element analysis ...
