The role of tool geometry in process damped milling [PDF]

, 2010
The complex interaction between machining structural systems and the cutting process results in machining instability, so called chatter. In some milling scenarios, process damping is a useful phenomenon that can be exploited to mitigate chatter and ...

Surface Roughness Modelling in Face Milling

Procedia CIRP, 2015
AbstractThe ability to plan the quality of surfaces is very important in manufacturing due to the fulfillment of requirements for parts machined by different methods. A method and a modelling procedure are introduced in the paper based on the definition of the relations between the calculated theoretical and the measured real roughness values of ...

Associations of Sleep and Shift Work with Osteoarthritis Risk

Arthritis Care &Research, Accepted Article.
Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships between circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000‐person cohort, we evaluated associations between sleep duration, sleeplessness/insomnia, and ...
