Chip formation - Wikipedia
Chip formation is part of the process of cutting materials by mechanical means, using tools such as saws, lathes and milling cutters. An understanding of the theory and engineering of this formation is an important part of the development of such machines and their cutting tools.
Study on Grinding Technology for Seafloor Mineral ...
The measurement of particle size of samples from the experiments showed that water-filled grinding had comparable grinding performance to wet grinding while the suitable rotation rate for water-filled grinding shifted to higher than that for wet grinding. This result suggests the possibility of water-filled grinding for seafloor mineral processing.

Effects of Grain Size and Operating Parameters on the ...
An investigation is described of the effects of grain size and operating parameters on the mechanics of grinding. Results indicate that the specific cutting energy in grinding, which is the total specific grinding energy minus the specific energy due to sliding between the wear flats and the workpiece, is independent of grain size and decreases with increasing table speed and downfeed.
