Whether you're using a high-speed stamping press to make simple parts at breakneck speeds or doing something really tricky, like deep drawing a material that puts up a lot of resistance, the information in this technology area is sure to help. The articles, case studies, and press releases cover stamping presses, lubricants, and materials.

Modern toolmaking methods and materials have reduced production time, cost, and headaches significantly over the last 20 years. But the rapid pace of the tooling revolution, coupled with extremely complex manufacturing technology, has left many people confused and misinformed.

Editor's Note: This article is Part III of a four-part series covering flatness and stability in cut-to-length, slitting, and tension leveling operations. This article discusses how coil processors can make metal flat so it stays that way. Part I, which appeared in the October issue of The FABRICATOR®, discussed how flat-rolled metal gets unflat; Part II in the November issue covered flattening solutions and the anatomy of a bend; and Part IV in the January 2003 issue will discuss new applications and options in leveling equipment.

Not all coil handling equipment is created equal. At first glance, conventional coil lines and straighteners-feeders seem to perform the same task, but when they are examined throoughly, these units are very different.

One of the most valuable high-tech tools introduced in the last decade has been finite element analysis (FEA) simulation software that stamping tool makers can use to test forming conditions and design dies in the virtual world. This reduces tooling and product design time and saves costs of prototyping and experimentation to find the right design. Training the tool designer or process engineer how to use simulation software can provide a quick ROI and improve the bottom line.

This is article is part 1 of a four-part series covering flatness and stability in cut-to-length, slitting, and tension leveling operations. This article covers how flat rolled metal gets unflattened, including the 3 categories of defects, how defects are created at hot and cold mills, and how coil processors also create defects.

Most metal forming operations use lubricants to protect the tooling and part from excessive wear caused by scuffing, scratching, scoring, welding, and galling. Four lubricant families are commonly used in pressworking, and thousands of formulations are available within each chemical family. The physical characteristics of the lubricant and metal forming operation involved determine the application method to be used.

Designing finger tooling that will work effectively with a transfer press die is now easier with the advent of modular, off-the-shelf finger tooling components. Through computer-aided design, stampers can minimize trail-and-error adjustments and reconfigure finger tools or modify die components to make part transfer possible.

For large volume parts runs, problems such as misfeeds, off-center hits and inadequate transfer webbing can cause slitting-induced strip camber. The production of camber-free slitting requires proper material selection, tooling, techniques and inspection practices.
