Journal ArticleDOI
Profile error compensation in ultra-precision grinding of aspheric surfaces with on-machine measurement
TL;DR: In this paper, a compensation approach based on the on-machine measurement was developed for the grinding of tungsten carbide aspheric molds, which was employed to eliminate the profile error caused by the re-installation of the workpiece.
Journal ArticleDOI
Brittle-Ductile Transition Phenomena in Microindentation and Micromachining
TL;DR: In this article, a generalized hypothesis for the brittle to ductile transition in micromachining and microindentation of brittle materials is proposed, which explains complicated transition phenomena observed in practical machining processes.
