With the aim of developing a cleaner and more environmentally-friendly aerospace industry, the Basque technological centre IK4-IDEKO presents the progress made in the manufacture of lightweight materials for the aerospace industry achieved in MMTech.

IK4-IDEKO hosted the sixth general meeting of the initiative presenting the progress achieved so far. The Elgoibar company presented the result of the new adaptive control system for the machining gamma-titanium aluminides (y-TiAl), some very light and resistant alloys which are considered the next generation of materials in the aerospace industry.

"y-TiAl alloys have enormous potential to displace other types of materials commonly used in the aviation industry, due to its extraordinary specific resistance. However, the drawback of these solutions is the high cost and processing difficulty. The purpose of MMTech is to overcome these obstacles in order to be able to manufacture these materials efficiently and more economically," says the project coordinator of IK4-IDEKO, Alex Iglesias.

IK4-IDEKO have succeeded in developing a revolutionary adaptive control system of vibrations during the machining process. "The system is based on an algorithm to detect vibration on the machine using built-in sensors. Based on the measured signal, an automatic variation is applied to the cutting conditions and active damping to stabilise the process", Iglesias explained. In addition, IK4-IDEKO also worked on the design of cutting tools specifically designed for stable machining under fixed conditions. Finally, the technological centre is involved in the development of active solutions such as machining with variable dynamic tools or robot-assisted machining.
