Publisher's Synopsis
Excerpt from Process Planning for Metal Forming Operations: An Integrated Engineering-Operations Perspective
This paper addresses planning and process improvement issues in metal forming Operations. Although metal forming has a broad interpretation, for the purposes of our discussions we exclude discrete Operations such as stamping, forging, cutting, drilling, welding, and machining operations. Thus, we are concerned mainly with operations such as hot and cold rolling, extrusion, and drawing.
The metal forming industry is characterized by large investments in plant and equipment, a wide range of product offerings, the strategic importance of process technology, and universal standards for specifying, measuring, and testing product quality. Because of the significant economies of scale, installing machines with large capacities, maintaining high levels of utilization for prime equipment, and improving process yield or recovery are important strategic objectives for the industry. In turn, these objectives of improving recovery and utilization have led metal forming companies to continually upgrade their equipment to handle larger ingot and lot sizes. In contrast, customers are placing smaller, more frequent orders as they move towards just-in-time procurement and production. The industry also faces increasing pressures to improve quality, reduce cost and lead times, and meet more stringent specifications. These trends make the planning and process engineering functions critical for competitive survival.
