Projects Development of a Punching-Broaching Tool for the Manufacturing of Holes in Steel Plates (GEKATOOL)
Development of New Thread Geometries for Metal-Plastic Assemblies in the Automotive Industry (HARIA)
Partners: Geka and tecnun Start date: 2015 – End date: 2016 Objectives: Numerical modeling of punching process using Finite Element Method (FEM) Influence of punching process parameters on punched hole quality and on the stress and strain fields generated in the plate by the process. Design and manufacturing of a punching-broaching tool able to remove damaged areas generated by the punching process. Broaching tests with the designed punching-broaching tool in steel plates of 5-15 mm thickness.
Partners: Panelfisa and tecnun Start date: November 2015 – End date: February 2017 Objectives: Analysis of thread forming process and tightening in self-tapping screws Numerical modeling of self-tapping process using Finite Element Method (FEM) Development of new thread geometries improving the metal-plastic assembly performance: Self–tapping Optimization of Screw installation torque. Reduction of friction. Increase of clamping force. Boss Delay of thread failure. 10 mm
