Ring Rolling has been one of the most computationally demanding simulations in metal forming. Traditional metal forming codes, require days, weeks or months to simulate typical processes. Even with extremely fast hardware, the 'brute force' methods are impractical.
Cogging is an open die forging process used to convert a cast ingot into forged billet. A typical process involves hundreds of local reductions, along the length of the billet, spanning several heats. The workpiece is typically rotated between or during passes.
The ingot cross section is reduced as it changes shape to a round, hexagon or octagon. This thermo-mechanical processing refines the coarse ingot grain structure to homogenized, fine grained, recrystallized billet microstructure.
A Geometry Tool is available to supplement the capabilities of many CAD systems when producing STL files. While some systems produce water-tight STL models with no folds, cracks or illegal polygons, this is not always the case. The Geometry Tool is capable of automatically repairing a wide range of illegal STL geometry. For severe cases, a user can detect and repair geometry interactively.
Inverse Property Extraction (2D): Accurate definition of local heat transfer coefficients as a function of temperature is required to accurately model transient thermal processes.
DEFORM provides an optimization-based inverse module that extracts heat transfer coefficients from experimental manufacturer of thermocouple data. This user- friendly module professional guides the user through data preparation and post processing. Modeling results include a set of heat transfer coefficients and temperature validation plots.
