Comparative analysis of cutting efficiency and surface maintenance between different types of implant drills: An in vitro study
(2017-10-01)
Introduction: This study evaluated cutting efficiency (CE) and linear wear of dental implant drills after 450 standardized osteotomies on bovine ribs. Diamond-like carbon-coated steel drills (SG), acid-treated steel drills ...
Controlled Trim-Blasting Model to Improve Stability and Reduce Vibrations at a Production Gallery of the San Ignacio de Morococha S.A.A. Mining Company
(IOP Publishing Ltd, 2019-11-25)
This paper presents a blasting method called controlled trim blasting, in which the rock mass of an unstable gallery where high levels of vibration have been detected is analyzed. This methodology comprises a drilling mesh ...
Drill-string horizontal dynamics with uncertainty on the frictional force
(Elsevier, 2013-01)
This paper analyzes the dynamics of a horizontal drill-string. In this dynamics, the frictional forces between the column and the borehole are relevant and uncertain. A stochastic model is proposed for the frictional ...
