Threading is the process of creating a screw thread. There are many methods of generating threads, including subtractive methods, deformative or transformative methods, additive methods or combinations thereof.
Although there are many types, more common is thread cutting, it’s because this operation can be carried out at the same machine used to machining the part, lathe or milling machine, and for his high quality and accuracy. This operation is able to make internal and external threads. To internal threads usually are made by a tool called tap, thus this operation is called tapping. External threads are made with a die the operation is called threading.
