AutoForm launches its new software AutoForm-ToolDeflect

AutoForm Engineering GmbH, cutting-edge supplier of software solutions for stamping and BiW assembly processes, presents its newly developed software AutoForm-ToolDeflect. The software allows for the efficient analysis and compensation of elastic tool deflection, a process known as over-crowning. The software can be easily applied in the early process design phase as well as in the final validation phase, enabling users to avoid unnecessary tryout loops and thereby improve production efficiency.

Tool deflection is an important issue in the manufacturing of dies and stampings, as it leads to an
increased number of tryout loops, rejects and press downtime in production. In order to ensure
efficient production, deflection has to be compensated. AutoForm-ToolDeflect enables users to
compensate for elastic tool deflection by automatically over-crowning tool surfaces.

AutoForm-ToolDeflect can be applied in the early process design phase when the final tool
geometry is not yet available in CAD. The newly developed “substructure generator” enables users
to create a draft tool substructure, so that initial tool design concepts can be quickly created based
on part geometry only. By analyzing various alternative concept designs, users can select the most
effective design with minimal elastic tool deflection.

The software can also be applied in the final validation phase by using already existing final tool

geometry data in CAD. When the tool deflection has been calculated, users can carry out an over-
crowning. The over-crowning results can then be used for the milling preparation. In this way,

AutoForm-ToolDeflect enables users to avoid unnecessary tryout loops and thus improve
production efficiency.

Dr. Markus Thomma, CMO of the AutoForm Group, stated: “Reducing tryout loops has always
been an important topic in tool shop departments, since each correction loop that can be avoided
provides an immediate advantage in terms of time and costs savings. Our newly developed
software AutoForm-ToolDeflect greatly supports customers facing such issues.”
