New methods to improve efficiency of grinding processes

New methods to improve efficiency of grinding processes
IK4-IDEKO will participate in the upcoming Advanced Manufacturing and Machine Tools Congress with presentations on the optimisation of machining operations. The event will take place between 25 and 27 October in the Scientific and Technological Park of Gipuzkoa

The use of technologically advanced techniques to optimise grinding operations helps boost competitiveness of industrial manufacturing processes.

The technology centre IK4-IDEKO, specialised in advanced manufacturing, is strongly committed to searching new methods to increase productivity and efficiency in machining processes. The result of this research will be presented at the upcoming Advanced Manufacturing and Machine Tools Congress.

The entity will present two technical papers at the 21st edition of the event organised by the Spanish Association of Manufacturers of Machine Tools (AFM) held between 25 and 27 October in the Scientific and Technological Park of Gipuzkoa.

More specifically, the researchers of IK4-IDEKO's manufacturing processes unit will read a paper describing a new kinematic model for the diamond-dressing process with a rotary disc.

This work, developed in collaboration with the Department of Mechanical Engineering of the University of the Basque Country, studies the implementation of a system that predicts the grinding wheel topography after a dressing operation with a rotating dresser.

Aitzol Galletebeitia, head of research in the technology centre explains: "Based on the geometry of the diamonds and the input parameters for the diamond dressing process, the model yields the resulting 3D topography of the grinding wheel, the approximate roughness profiles and a quantification of the volume of removed material in the process."

 The participation of IK4-IDEKO at the congress is completed with a conference on the "state of the art of the different approaches to grinding surfaces", presented by the researcher Lander Urgoiti. This is a study focused on the classification of different strategies used in grinding of surfaces, as well as on a compilation of the superficial analysis of the kinematics and on a research of the necessary technological requirements.

Grinding surfaces is a critical process in the manufacture of parts for strategic sectors such as the automotive, aeronautics and energy producing sectors.

Urgoiti further specifies: "This process can be approached in different ways, but there is a large gap of specific information concerning the kinematics of each method, as well as of the most suitable formulas in each case: this work is a first step toward a more in-depth analysis for the definition of the method and the optimal cutting parameters."

The Advanced Manufacturing and Machine Tools Congress organised by AFM- the Spanish Association of Manufacturers of Machine Tools, seeks to disseminate the main developments and trends in the manufacturing sector from a scientific-technical perspective, complemented with innovative processes or talent management.
