IDEKO research centre, a member of the Basque Research and Technology Alliance (BRTA), will attend the 19th Conference on Modelling Machining Operations (CMMO), organized by the International Academy of Production Engineering (CIRP) in Karlsruhe, Germany, from Wednesday 31 May to Friday 2 June.
This event will bring together international experts from academia and industry with the aim of discussing the latest developments in the industrial machining operations modelling sector.
As a technological benchmark in the field of R & D for industrial processes, IDEKO will have a prominent role in this conference. In particular, two researchers from the research center, Ainhoa Robles and Iker Urresti, from the Manufacturing Process research group, will present two solutions to improve turning and milling operations.
Higher productivity
The first day of CMMO will feature a talk by researcher Ainhoa Robles who will explain the work done at IDEKO on “Deflection error modeling during thin-wall machining”. During her talk, she will show the capabilities of the model developed for predicting the forces and deformations during the milling of thin-walled components for aerospace indutry.
It is necessary to minimize the cutting forces of the machining process to avoid deformations. Their low stiffness generates the need to minimize the cutting forces to avoid deformations, inducing low Material Removal Rate (MRR) and low productivity values.
“To avoid deformation problems of thin-walled components, the aim of this work has been to develop a system for predicting forces and deformations generated during milling. In this way, we have developed a model that compensates the generated deformation without modifying the cutting conditions of the machining process, thus maintaining productivity”, explains the researcher.
The second talk, “Surface Integrity Modelling for Cryogenic-assisted Hard Turning: A hybrid approach,” will be given by the researcher Iker Urresti. Cryogenic-assisted hard turning emerges as sustainable machining process. Nonetheless, the control of surface integrity for avoidance of surface defects such as white layers and tensile residual stresses is still a challenge. During his presentation, scheduled for Friday, June 2, Urresti will delve into the challenges that arise in cryogenic-assisted turning operations on hard surface part and will present a hybrid surface integrity model developed in his work. The model is comprised by a 3D Finite-Difference Method (FDM) thermal model, which is able to simulate the cryogenic cooling conditions in addition to the tool flank wear effect. Afterwards surface hardness and material phase transformations (white & dark layers) are predicted using empirical models.
In order to deal with this problem, the researcher will present a hybrid system of surface integrity developed by IDEKO that can simulate in 3D the cryogenic cooling conditions during turning and the tool flank wear effect. “Thanks to the collection of these data, we can predict the hardness of the surface of the material being treated, as well as the possible transformations it may undergo and therefore analyze how tool wear and cryogenic cooling affect the quality and condition of the piece,” explains Urresti.
