Die Science: Diemaker or dieologist?

February 28, 2017 | By Art Hedrick

If you have ever attended one of my technical seminars, you know that I often use the word dieologist. Don’t waste any time trying to find it on the Internet, because you probably won’t. It’s a word that I made up and frequently use to define a diemaker who uses his or her knowledge of sheet...

Die Science: The basics of servo-drive presses

February 28, 2017 | By Art Hedrick

As materials change and the competition gets tougher, metal stampers must invest in technology that helps them to remain competitive. In stamping, efficiency is everything. Stampers must produce higher-quality parts in shorter cycle times using materials that often have poor formability. This is an...

Die Science: Opportunity knocks

February 24, 2017 | By Art Hedrick

When you think of the tool and die industry, you often think first of tool- and diemakers—people grinding die sections, reading engineered drawings, assembling dies, and trying out tooling. Although tool- and diemakers are critical to the diemaking process, many jobs are equally important to the...

Die Science: The influence of product design

February 24, 2017 | By Art Hedrick

I find it somewhat disheartening how often product designers fail to see the downstream effect of the decisions they make regarding the design of a stamped product. Poor tolerencing and part feature decisions cost the stampers and die builders any profit they may have realized. While I don’t want...

Die Science: Die costing and estimating

February 24, 2017 | By Art Hedrick

One of the common complaints I hear from stampers is that tooling cost estimates differ significantly when they are requesting quotes. One would think that if every shop were quoting to the same die design standards, the tooling cost would be similar from each shop quoting, but that’s not the...

Die Science: What makes a topnotch metal stamping plant?

January 11, 2017 | By Art Hedrick

Some stamping plants and die-building facilities are far more productive and efficient than others. Each shop typically has its own niche, as well as its own strengths and weaknesses. So what are the key decisions managers make that result in a successful stamping or die-building shop? Staffing...

Die Science: Estimating die cost

December 2, 2016 | By Art Hedrick

Before receiving a contract to design and build a die, the building shop must quote a price to the customer. Because every die usually is a one-of-a-kind tool, the process of quoting tooling cost is not always easy. The person estimating this cost must have a good understanding of sheet metal...

Die Science: How many hits does it take to get to the end of a tool’s life?

July 7, 2016 | By Art Hedrick

Recently I was asked at a training session to state the average life of a stamping die. The person asking was from the costing department of a large automotive firm. He said he needed to know because he was getting different answers from different individuals in the organization—anywhere from...

Reading progressive die strip — Part II

June 16, 2016 | By Art Hedrick

Editor's Note: This is the second part of a two-part article about reading progressive-die strips. Part I, which appeared in the May issue, covered the causes of pilot hole distortion and mismatched cuts. Hard marks, otherwise known as coin marks, occur when metal is severely squeezed between two...

Die Science: Solving punch breakage problems - Part III

June 16, 2016 | By Art Hedrick

Numerous factors contribute to the premature failure of piercing and cutting punches. In addition to problems with the punches, such as tool steel or problems caused by EDM and grinding, the press can cause problems through deflection, and bridge strippers also can cause punch breakage.

Die Science: Designing dies 2-D or 3-D?

June 16, 2016 | By Art Hedrick

Both 2-D and 3-D die design packages have advantages and disadvantages, which are discussed here, but true success lies in the designer's ability, not the software's.
