The thread pitch is generated by inclining the roller axes by the pitch angle The workpiece is given an axial thrust and moves by one thread pitch in an axial direction with a full rotation Overlength threads can be made in this way Thread cutting In this procedure the thread is made by means of a tap or a screw stock

Screw thread Wikipedia

A screw thread often shortened to thread is a helical structure used to convert between rotational and linear movement or force A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix with the former being called a straight thread and the latter called a tapered thread A screw thread is the essential feature of the screw as a simple machine and

Screw simple machine Wikipedia

The thread angle is the included angle measured at a section parallel to the axis between the two bearing faces of the thread The angle between the axial load force and the normal to the bearing surface is approximately equal to half the thread angle so the thread angle has a great effect on the friction and efficiency of a screw as well as the wear rate and the strength
