A special thread form keeps bolts and nuts tight under vibration by attacking the problem from a different angle. Two conventional methods for securing threaded fasteners against preload loss include ...

Historically, hole threading has primarily been done using cutting taps, typically made from high-speed steel (HSS). These taps remain widely used in high-volume production where many identical holes ...

There are many elements to consider when threading a workpiece. When is a solid carbide thread mill better than an indexable? How does the workpiece material behavior impact thread milling?

Abstract: This paper presents a detection method of thread image based on support vector machine. This method is to obtain a training sample set by collecting every concrete sub-image of thread form ...
