IK4-IDEKO shares it knowledge on advanced robotics and dynamic machinery control in Tokyo

The technology centre had a notable presence in the conference programme of the CIRP General Assembly, held from 19 to 25 August in the Japanese capital.

The IK4-IDEKO researchers shared their knowledge on, among other scientific fields, the most innovative technologies for applying robotics to industrial milling and the most advanced techniques for eliminating vibrations in manufacturing processes, at the General Assembly of the International Academy for Production Engineering (CIRP) held from 19 to 25 August in Tokyo.

The specialists from the Elgoibar technology centre had a notable presence in the conference programme at the assembly, which was organised by the leading international entity in research applied to Advanced Manufacture.

The director of the Dynamic and Control research line at IK4-IDEKO, Jokin Muñoa, collaborated in a presentation on robotics within the COROMA project framework, an initiative coordinated by the Basque technology centre that seeks to develop a new modular and flexible robot concept capable of executing multiple industrial processes.

Titled “Robot assisted milling to increase productivity” and developed in collaboration with the AMRC group, the talk explained how the use of robotic solutions for assisting milling allows improvements to be obtained in the static and dynamic response of the process, which achieves an increase in surface quality of the machined parts and minimises the generation of dimensional errors.

Meanwhile, researchers Alex Iglesias and Zoltan Dombovari, in collaboration with the University of Budapest, participated in a presentation in which the advances achieved in the European MMTech project were detailed. This project seeks to develop new methods and technologies for the manufacture of components in titanium alloys for the aerospace industry.

Specifically, the experts addressed the impact of what are called stabilisation in the milling process diagrams when cutting tools with differential pitch are used, that is cutters that have a variable distance between teeth.

The use of differential pitch cutters is intended to improve the performance of the process, but the existing solutions on the market do not always achieve this. The research carried out by doctors Iglesias and Dombovari demonstrates that in order to optimise the results of these tools, the dynamic behaviour of the machine, the cutter and the process must be taken into consideration.

Lastly, the researcher David Barrenetxea, also an associate member of the CIRP, gave a talk on new devices for suppressing chatter in centreless grinders.

Specifically, the specialist presented an innovative active damping technique based on inertial actuators that make it possible to eliminate vibrations during the manufacturing process, guarantees the quality of the final part and increases grinding productivity.

Damping is a key property for the functioning of machine tools, since it contributes to stabilising processes with low vibration and noise levels. Therefore, it has a decisive influence on the useful life of the mechanical components and on the final quality of the parts.

The presentation, called “Productivity increase in centreless grinding through the use of active inertial dampers”, is a result of the collaboration of the Dynamic and Control research group and IK4-IDEKO's grinding processes specialist team. The research took place within the CIMEC project framework that seeks to develop cyber-physical systems for improving the efficiency of the energy industry.

CIRP's General Assembly has the aim of promoting R&D applied to manufacture through an international network of researchers who share their knowledge and analyse the future prospects in fields such as manufacturing processes and system automation and manufacture.
