A Review on Chatter Analysis in Cold Rolling process

common process of cold rolling operation known as chatter. This happened due to numerous discrepancies occurring during manufacturing process, such as roll vibration, variation in strip tension and negative damping [1]. Chatters lead to thickness variation (across the width), surface damage and undesirable noise at work place.

Sheet Camber and Cambering of Rolls | Metallurgy

During rolling the working roll ends would deflect towards backup roll, thus creating a camber on working roll surface which is in contact with the sheet. The method is highly useful in automatic control of camber. This type of control is easily adaptable in computer control of cold rolling mills. Rolling Practice V/S Anisotropy in Sheet Metal:

Rolling Process: Definition, Working Principle ...

Rolling Process Definition. The rolling process is a metalworking operation in which metal strips pass through a set of rollers to reduce sheet thickness and achieve uniform thickness throughout the sheet. The sheet is deformed along the linear axis. Typically after the rolling, metal sheets go through annealing which is done under a closed environment of nitrogen.
