Rolling torque is the process of applying a rotational force to a rotating object to create rotational motion. It is usually used in manufacturing processes such as forming, cutting and welding.
Rolling torque involves the application of an external force, usually by way of a motor or other machine, to cause rotation of an object. The applied force is usually in the form of a linear torque which is the product of the force and radius of rotation. This force is applied in order to shape materials into desired shapes through the process of metal rolling, which is the deformation of metal into a new shape using two opposing forces.
In metal rolling applications, the rolling torque is the force applied in order to deform the metal and is usually related to the size and thickness of the workpiece. The force required to deform the metal also depends on the size and hardness of the material being rolled. In order to ensure maximum material strength and durability, the applied force must be greater than the resistance of the metal.
Rolling torque is most often used to form circular or convoluted shapes in metalwork. The shape of the object is governed by the kind of rolling used, the speed of rotation, and the applied force.
In metal cutting applications, the rolling torque provides the impetus required to cut the metal through a die or rolling press. The cutting force applied to the cutting tool causes the metal to be deformed and, thus, is dependent upon the strength of the metal and the type of metal cutting tool used. In addition to cutting metal, rolling torque can also be used to stretch and shape metal in a process known as metal fabrication.
The force of rolling torque is also used in welding applications. The applied force heats the metal and, in turn, causes the metal to fuse together. This type of welding is called fusion welding and is used in the manufacture of parts such as pipes and tubing.
The importance of rolling torque lies in the fact that it is necessary to ensure the efficient and safe functioning of many machines and devices. Thus, understanding and controlling the rolling torque is an important part of any metalworking or manufacturing process. Rolling torque can also be used to measure the forces applied to rotating objects, allowing for the application of force in applications such as robotics and automotive manufacturing.
