Fatigue performance is a serious concern for mechanical components subject to cyclical
stresses, particularly where safety is paramount. The fatigue performance of components …

A correlation between machining process and fatigue strength of machined components
clearly exists. However, a complete picture of the knowledge on this is not readily available …

In recent years, the production of renewable energy has increased continuously to reduce
fossil fuel consumption and CO 2 emissions and to increase energy efficiency. The …

A 2 2 full factorial design of experiment is used to investigate the effects of two machining
platforms (5-axis elevated gantry versus 6-axis articulated robotic system) and two cutting …

Drill-pipe tool joints in extended reach wells often suffer a shear failure. In view of this, an
ultra-high torque double-shoulder pipe joint was designed according to the deformation …

Thread connection is one of the main unions for oil tubing and casing and its failure leads to
deterioration of seal performance and connection strength. The machining process that …

In this study, the influence of non-metallic inclusions on the fatigue behavior of 30MnVS6
steel containing different inclusion sizes and surface roughness has been investigated …

The main difficulties of shaping of internal treads with the required accuracy in aluminium
alloys caused by a built-up edge were studied in this paper. A new design of deforming …

The strain hardening and the formation of the residual stresses at the roots of threaded joints
produced by machining according to American Petroleum Institute (API) standards was …

External thread cutting is a complex 3-D process in which the cutting conditions vary over
the thread cutter profile. It is accepted as a mature technology. However, thread machining is …
