Polarisation-mode coupling in (100)-cut Nd:YAG

Optics Express, 2006
We investigate the polarisation-mode dynamics and Lamb's mode coupling constant for orthogonally polarised laser states in a dual-mode (100)-cut Nd:YAG laser with feedback, and compare with an anisotropic rate equation model. The anisotropic (100)-cut Nd:YAG exhibits thermally-induced depolarisation and polarisation-mode coupling dependent on the pump ...

Assigning the turning mode based on assessment of the dynamic quality of machine tools

Известия высших учебных заведений. Поволжский регион:Технические науки, 2023
Background. Machining on lathe machines using automation means is a complex process that depends on the properties of the dynamic system (DS) of the machine, therefore, determining cutting modes based on the minimum value of the attenuation coefficient

Experimental study of coated carbide tools behaviour: application for Ti-5-5-5-3 turning [PDF]

, 2011
The goal of this paper is to study the relation between the input data (conditions and geometry of cut) and answers (wear of tool, forces and cutting temperatures) when machining the Ti-5-5-5-3 alloy treated. This study has shown that the cutting process

Predictive plots for conical pick performance using mechanical and elastoplastic properties of rocks

Journal of Rock Mechanics and Geotechnical Engineering, 2020
Conical picks are by far the most widely used drag type cutting tools employed on partial face rock excavation machines. The cutting force and specific energy are two important design parameters for the conical pick performance, and the rock cutting ...

Investigation of Cutting Tools and Working Conditions Effects when Cutting Ti-6al-4V using Vegetable Oil-Based Cutting Fluids

, 2015
Power consumed in metal cutting is typically converted into heat near the cutting tool edge. Cutting fluids are then provided to a cutting zone in order to improve the tribological characteristics of machining processes and to dissipate the generated ...
