ickel-based superalloys can be characterized by resistance to high-
temperature corrosion and high-temperature creep resistance. For this
reason, they are widely used in the production of jet engine critical parts. One
of the commonly used materials is Inconel 625, which will be the subject of
this research. For Inconel 625 processing, rotary forming can be applied, which
results in axially symmetrical elements. An important property of Inconel 625
is strong strain hardening effect. To improve formability, variety of methods
can be applied, including heating of the material. The purpose of the research
was optimization of rotary forming process parameters of Inconel 625 to
produce jet engine critical parts with high quality requirements. Scans data
were processed in GOM Inspect software. For further analysis, thickness and
surface deviations for all points and zones of interest were needed, as well
as various statistics as extrema, standard deviation, deviation distribution,
and tolerance tests. As obtaining this data manually would be extremely time
consuming, Python scripting GOM API was utilized. With created scripts we
automated loading, aligning, comparing of scans and CAD model, calculating
measures and required statistics. Generated data was then used in multivariate
optimisation for selecting optimal process parameters. Deviation statistics
were modelled with regression models, predicting selected quality measures
depending on trials parameters. Based on thesemodels, overall quality function
was maximised with GridSearch approach, yielding optimal parameter for the
process.
