There are many methods of generating threads, including subtractive methods (many kinds of thread cutting and grinding, as detailed below); deformative or … Ver mais There are various methods for generating screw threads. The method for any one application is chosen based on constraints—time, money, degree of precision needed (or not needed), what equipment is … Ver mais Thread forming and rolling Thread forming and thread rolling are processes for forming, rather than cutting, screw threads, with … Ver mais Often subtractive, additive, deformative, or transformative methods are combined in whatever ways are advantageous. Such multidisciplinary … Ver mais Inspection of the finished screw threads can be achieved in various ways, with the expense of the method tailored to the requirements of the product application. Shop-floor inspection of a thread is often as simple as running a nut onto it (for male threads) or a bolt … Ver mais Thread cutting Thread cutting, as compared to thread forming and rolling, is used when full thread depth is required, when the quantity is small, when the blank is not very accurate, when threading up to a shoulder is required, when … Ver mais Many, perhaps most, threaded parts have potential to be generated via additive manufacturing (3D printing), of which there are many variants, including fused deposition modeling, selective laser sintering, direct metal laser sintering, selective laser melting Ver mais Each method of thread generation has its own detailed history. Therefore, a comprehensive discussion is beyond the scope of this article; but much historical information is available in related articles, including: • Ver mais
