End mill design and machining via cutting simulation
TLDR
We use the cutting simulation method to obtain the machined shape of an end mill by using Boolean operations between grinding wheel and a cylindrical workpiece (raw stock). Expand

Mill-grinding with electroplated diamond abrasives for ceramic cutting
Ceramic materials are very hard and brittle and are not easily cut with typical methods, such as grinding or cutting. These materials are cut mostly using the grinding process, but the material… Expand

Elimination of Settling Error Due to Clamping Forces in On-Machine Measurement
When using OMM (on machine measurement), accuracy in the measurement of finished, machined parts is important; these parts are commonly measured by CMMs (coordinate measuring machines). This paper… Expand
