Helix Angle: When you have a straight thread, the helix angle is that which the helix makes in relation to the thread axis. The pitch diameter is the diameter of the theoretical cone or cylinder. Pitch: This is the distance a parallel area measured between corresponding areas on adjacent threads. It is the immediate adjacent area to the cone or cylinder where the thread projects. Root: The root is the thread surface joining the flanks of adjacent thread forms. Theoretically, the intersection of a flank surface with an axial plane is a straight line. That is, it is the top of threads.įlank: A thread’s flank connects the crest with the root. The crest is the farthest area from the cone or cylinder where the thread projects. The following terms will help you better understand machining threads:Ĭrest: This is the surface of the thread that joins the flanks. Consequently, the motion can help obtain mechanical advantages. There’s the transmission of motion as a result of the coupling. The cap and the bottle top couple to give a tight water seal. You’ll get a great picture of threads when you think of your water bottle cap. It can form on the nut (internal) or on the screw/bolt (external) surface.Ī thread’s primary function is to act as a coupling between two mechanisms. The helical ridge comes with a uniform section on different surfaces of a cylinder or cone. What Is A Machining Thread in Manufacturing?Ī thread refers to a continuous helical ridge. Read on to find out important information about machining threading. For the sake of your profit margins, it is important to explore the different threading technologies available. However, these processes remain among the most efficient ways of producing screw threads. The thread cutting processes also seem to have several shortcomings. Therefore, it becomes increasingly challenging to identify the right threads for your applications. The global marketplace now contains a wide range of connectors and fittings. No manufacturer should ever take machining thread for granted. Order by 5pm EST and we will ship out the same day.Threading parts is a fundamental metalwork process.
