A countersunk hole is a cone-shaped recess, and it is cut at the top of a drilled hole. It is primarily used to hold a screw and bolt with a tapered head. It allows the screw to sit flush with the ...

Dimensional metrology allows engineers to ensure fabricators meet precise line pipe specifications. The interplay between dimensional metrology and both fit-up and automated ultrasonics technology can ...

Offering both speed and strength, a new counterboring tool has what it takes to make the cut in a variety of challenging applications. So says the manufacturer, Heule Tool Corp. in Loveland, Ohio, ...

A containership’s propeller blade cracked leading to a loss of hydraulic oil and propulsion while transiting the Pacific Ocean, the National Transportation Safety Board (NTSB) said recently. The ...

Bridging changes to a direction that provides sub-optimal support with respect to the solid infill above it surrounding the inner hole. I think the bridging direction should remain perpendicular to ...

The AS5202-X series is a brand-new style of port tools by Scientific Cutting Tools that meets the requirements of AS5202, MS33649, and AND10050 port specifications. This tool offering is ideal for non ...

Abstract: As one of the most basic and most important processes of mechanical processing, counterbores often have defects such as skew corners and inconsistent dimensions. How to quickly detect the ...

The increase in injection pressure makes it more challenging to accurately control the injection quantity of the injector of a gasoline direct injection (GDI), thus necessitating the optimization of ...

Abstract: This paper proposed an algorithm to recognize intersection cylindrical feature, especially counterbore and countersink geometry. The proposed algorithm analyzes 3D solid drawing in term STEP ...
