DB4ISF: An incremental sheet forming database

DB4ISF

DB4ISF is an incremental sheet forming database consisting of 76 forming experiments executed by the Chair of Production Systems at Ruhr-Universität Bochum.

The database consists of the following data:• General process data (tool radii, sheet thickness, step depth, ...)• CAD files (stl, sldprt including CAMWorks toolpaths)• Toolpaths (surface points and normal vectors)• Robot programs used for forming (KRL)• Digitization (CDB)• Deviation of every toolpath point in normal direction• Precalculated surface representations for machine learning

Publication and reference

A publication that describes the methodical approach for building up the database and the experimental data inside it can be found here:Möllensiep, Dennis; Schäfer, Jan; Pasch, Felix, Kuhlenkötter Bernd. Cluster analysis for systematic database extension to improve machine learning performance in double-sided incremental sheet forming. International Journal of Advanced Manufacturing Technology (2024). https://doi.org/10.1007/s00170-024-14014-8.

Please cite the corresponding publication too if you are using the database for your own research.

ML4ISF

ML4ISF is a Matlab Framework with a GUI for the application of machine learning in incremental sheet forming and fully compatible with the database. 

The framework offers the following features:• Data management• Toolpath import with various presets• Calculation of surface representations utilized for machine learning• Generation of training data tables for machine learning in python• Prediction of the forming accuracy with several provided artificial networks• Toolpath adjustments based on the prediction and smoothing of the path• Generation of Kuka robot programs (other exporters could be implemented)• Various plotting functions

Prerequisites:• Surface toolpath with the corresponding normal vectors• STL file of the part

The framework was developed for the application of double sided incremental forming (DSIF) utilizing two industrial robots where the supporting robot applies a defined support force. Other methods such as SPIF with NC-machines can be implemented with slight modifications.
