Due to its good cutting performance in titanium alloy machining, integral end mills are more and used machining aero-engine impeller blades. The tool spiral groove plays the role of chip acceptor removal, accuracy parameters has an important effect on performance. In grinding process groove, wheel’s external is mainly involved task. wear degree related time times wheel, wheel will lead change g...

This paper establishes a granular mechanics model for the stable movement of material particle group in vertical screw unloader with mechanics, continuum and theory innovatively proposed hypothesis that speed changes radially spiral groove. Through analysis movement, characteristic parameters are determined. The study found free surface type longitudinal section conveyor its identification solu...

Medical microrobots have been widely used in clinical applications, particularly the spiral type locomotion mechanism, which was recently considered one of the main self-propelling mechanisms for the next medical microrobot to perform tasks such as capsule endoscopy and drug delivery. However, limits in clinical applications still exist. The spiral action of the microrobot while being used for ...

The humeral head articulates with the glenoid fossa of the scapula. The anatomical neck separates the greater and lesser tuberosities from the humeral head. The long head of biceps runs between the tuberosities in the bicipital groove, and the surgical neck is just below the greater and lesser tuberosities. The radial nerve runs posteriorly around the middle third of the humeral shaft in the sp...
