THREADING

Threading is a process wherein a screw thread is used to swap between a rational movement and a linear movement of force. The screw thread is a slanting plain that is circled around a conic or cylindrical shape. The threading fastener is like driving a wedge into a particular gap till it is attached to it with the friction and a small amount of plastic dis-formation as well. The pitch of the thread screw will be chosen in a manner so as to provide sufficient amount of friction to keep the linear motion from changing into a rotation. In this way, the threading screw stays in place even if the linear force is continued and the rotation is stopped. This feature is a very essential component of all threading operations.

Threading screws are applied in various systems, some of which are: in fastening for wooden screws and nut-bolt combinations; to connect threading pipes with hoses or the caps in fixtures; to reduce the gearing of worm driven systems; to move objects in a linear form like in screw jacks; to integrate linear and rotational motion; in a lead-screw to combine linear motion and measure it at the same time. In the above applications, the threading screw has 2 major functions, to convert from rotation to linear motion and to stop linear motion without affecting rotational motions.

In threading, every single thread screw has a pair, which is segregated into male and female counterparts. Like a thread screw has male threads, and the hole with it, which may be a nut or a bolt, will have female threads. This phenomenon in threading is known as the gender system. The helix system of threading has the ability to twist itself in tow different directions which is known as its handedness property. This follows the rule called as a right hand thumb rule, which means that when the thread screw is turned, it moves clockwise, and when it is reversed it moves anti-clockwise.
