TL;DR: In this article, the experimental evidence for what is the nature of the friction contact between chip and tool during continuous chip formation and the historical development of friction models is reviewed, through numerical simulation of the turning process.
••
TL;DR: In this article, the authors extended Nayak's analysis of isotropic surface roughness as a random field to show that most summits are only mildly ell, the most common ratio of principal summit curvatures being near 2:1.
••
TL;DR: In this article, it was shown that the size effect in friction can be described by the general friction law developed by Wanheim/Bay, which can be explained by the model of open and closed lubricant pockets characterising the surface topography.
