IDEKO showcases its latest advances in machining processes at CIRP CMMO 2025

IDEKO participated in the 20th edition of the CIRP Conference on Modeling of Machining Operations (CMMO), held on May 22 and 23 in Mons, Belgium. This internationally renowned event brings together experts from around the world to share the latest developments in machining operations modeling, a key area for high value-added manufacturing.

During this edition, two IDEKO researchers presented their scientific advancements in grinding and drilling processes applied to demanding sectors such as aerospace.

María García presented the work titled "New Geometric Stability Maps for Predicting Unstable Lobe Regeneration During Shoe-Type Centerless Grinding with Tilting Shoes".

This study addresses improvements in the shoe-type centerless grinding process, widely used for finishing bearing rings and known for its high precision and productivity. The research focuses on the geometric regeneration of unstable lobes, a critical phenomenon that directly affects surface quality and the service life of the component. The IDEKO team developed new geometric stability maps capable of predicting workpiece behavior based on the angular configuration of the support shoes, enabling process optimization and reduced setup times.

Iker Urresti, on the other hand, presented the study "Exit delamination failure modelling during drilling of CFRP laminates". 

The research focuses on the drilling of CFRP (carbon fiber reinforced polymer) laminates, a key process in the assembly of aerospace structures. It introduces a predictive model to estimate exit delamination and thrust force evolution during drilling — a critical defect that can compromise structural integrity. Compared with experimental data, the proposed model offers a valuable tool to progress toward delamination-free drilling processes, enhancing the reliability and efficiency of aerospace component manufacturing.

Through its participation in CIRP CMMO 2025, IDEKO reaffirms its commitment to applied scientific research aimed at improving machining processes, a crucial driver of technological transformation in the industrial sector.
