Conventional Rule-of-Thumb Calculations Lead to Inaccurate Press Tonnage Predictions
The rule of thumb estimates used in 1989 during my internship with an automotive stamping supplier were simple calculations for the peak load. Tonnage for trim and pierce operations depended on the length of line of trim, material thickness and the shear strength of...
Servo Press Force and Energy Considerations When Working With AHSS
Advanced High-Strength Steel (AHSS) products have significantly different forming characteristics and these challenge conventional mechanical and hydraulic presses. Some examples include the dramatically higher strength of these new steels resulting in higher forming...
A New Global Formability Diagram
Bubble chart. Banana diagram. Steel strength ductility diagram—it’s been called a lot of things over the years. But the 2017 chart shown in Figure 1 is the subject of hundreds of requests for use we receive from engineers and students all over the world and appears in...
Additive Manufacturing
Additive Manufacturing (AM) has been associated with the future of manufacturing since its inception. While it does hold several advantages in complex geometries and low-volume production, modern AM systems have yet to make significant in-roads with direct-print parts...
Vision for Industry 4.0 in Sheet Metal Forming
There is interest in the sheet metal industry on how to adopt Industry 4.0 into their legacy forming practices to significantly improve productivity and product quality. Figure 1 illustrates four important variables influencing part quality: material properties, die...
Welcome to the All New AHSS Application Guidelines!
The leading source for technical best practices on the forming and joining of Advanced High-Strength Steels (AHSS) for vehicle manufacture is released today by WorldAutoSteel, the automotive group of the World Steel Association. The AHSS Application Guidelines Version...
