Advanced computer aided design simulation of gear hobbing by means of three-dimensional kinematics modeling [PDF]

, 2006
Summarization: Gear hobbing, as any cutting process based on the rolling principle, is a signally multiparametric and complicated gear fabrication method. Although a variety of simulating methods has been proposed, each of them somehow reduces the actual

CAD-based calculation of cutting force components in gear hobbing [PDF]

, 2012
Summarization: Gear hobbing is a common method of manufacturing high precision involute gears. The thorough knowledge of the developed cutting forces and the wear of the cutting tool are of great importance in order to produce helical and spur gears as ...

Heat Flux and Temperature Distribution in Gear Hobbing Operations [PDF]

, 2013
Thermal deviations in gear hobbing are one of the main reasons for wet machining. To reduce lubricant, especially for dry machin- ing of large modulus, it is necessary to compensate these thermal deviations.Gear hobbing is a very complex technology ...

Fatigue fracture investigation of cemented carbide tools in gear hobbing, part 1: FEM modeling of fly hobbing and computational interpretation of experimental results [PDF]

, 2002
Summarization: Gear hobbing is a highly utilized flexible manufacturing process for massive production of external gears. However, the complex geometry of cutting hobs is responsible for the almost exclusive utilization of high-speed steel (HSS) as ...

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Vegetative Propagation Preserves Genomic Diversity and Informs Translocation Strategies in a Rare Clonal Plant

Evolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Conservation translocations are widely used to increase population size and redundancy, yet their genetic consequences are often uncertain, particularly for clonal species with unknown rates of sexual reproduction. Propagation through asexual reproduction is frequently employed in these systems, but its effectiveness for preserving genomic ...
