How part and die design go hand-in-handWhen engineers complete a part, then start on tooling design,
inefficiencies mount. Ideally, part and tooling design should go hand
in hand, and today a method exists that allows engineers to resolve
part and die forming problems before designers invest in a lot of
drafting.

Draw Forming, Part VIISetting the processing variables is different between the net shape and non-net shape processes. While non-net shape variables have to be programmed constantly to change the tool's position in space to follow the unique shape of the part being made, the shape of the part for the draw forming net...

Draw forming, Part VIEnergy input at one location in a part during forming is redistributed throughout the part as the forming process advances. The result must be an adequate force transmitted back to the location of target strains and displacements.

Draw forming, Part VThe remoteness of the energy-affecting elements contributes to the differences between the net shape and non-net shape processes. This additional difference helps drive the nature of the net-shape processing theory.

Draw forming, Part IVThe relationships among part geometry, tool geometry, and control of the processing inputs are significantly different between the net shape and non-net shape processes.

Draw forming, Part IIIThe connections between product conditions and product input variables for draw forming must be made through the intermediary transformation characteristics: plastic strains and displacements. So all product requirements must be redefined as the changes (or transformations) required of those two...

21st century stamping material specificationsAdvanced technology in the metal stamping industry has rendered obsolete traditional methods of selecting, specifying, and supplying material. Using modern technology to quantify materials can reduce the occurrence of material variation exceeding the die and process capabilities and make die...

Draw forming, Part IIIn draw forming, measurement and quantification are essential to ensuring part quality for the customer. However, the product requirements and the product input variables have different metrics and different conceptual meanings, which seems to defy direct engineering. Three processing variables...

Draw forming, Part IDraw forming is one of the net shape processes, and, as a result, many of the technology advances in the general field of manufacturing have not been as beneficial to draw forming as one would expect. All too often, such advancements as lean manufacturing, statistical process control,...
