Abstract

Increased quality requirements by rolling mills in recent years have resulted in a need for both manufacturers and users to understand the basic form characteristics of roundness and runout. These characteristics help determine how rolls interact with strip to provide smooth, chatter-free surfaces to the final product. Roundness and runout as well as the related characteristics of concentricity and eccentricity are common requirements on drawings but are often misunderstood and misapplied. The purpose of this paper is to clarify what each of these characteristics represents and to offer some suggestions in resolving common problems related to attaining customer requirements.
