Mecatrónica And processes centred/centered the days during two days

Ideko IK4 organises/organizes some technical days to celebrate his anniversary

Ibon Linacisoro11/11/2011

With reason of his 25 anniversary Ideko IK4 prescindió of superficialidades to celebrate the ephemeris with what better knows, the technology. During two days (27 and 28 October) invited to experts of diverse countries to speak in front of some 100 people on diverse subjects related with the machine-tool. During the first day had more weight the mecatrónica, while the segundó centred/centered in the processes of manufacture.

The attendant of the first presentation was Edorta Larrauri, Director of Technology of the Basque Government, the one who established the aim for the year 2015 of 3% of the GDP of investment in R&D. It affirmed that “Euskadi has to advance putting in value his capacities; it is necessary to motivate the private investment and Euskadi has to give a qualitative jump from the capacities of the system to the exploitation of these capacities to obtain results in shape of companies, patents and impact on the economy”. It added: “it is not true that the emergent countries are remaining with the production of low cost. Besides, they are betting by the R&D and in this terrain have to compete”.

Followed him, opening the technical reports Christian Brecher of the WZL RWTH Aachen, that spoke of the machines-virtual tool. Regarding the mechanical behaviour/behavior of the MH, spoke of the current situation of the simulation of the static behaviour/behavior (importance of the rigidity), the dynamic (importance of the mass and the damping) and the thermal (importance of the conductivity). “If we comprise the static behaviour/behavior, dynamic and the thermal can advances in subjects related with the interaction of the structure and the control”.

Also referred to the importance of the behaviours/behaviors in process electro-mechanical and process of court and of the importance to be able to attain some virtual studies the most next to the possible reality. It said, for example, that regarding the statics nowadays can hit with little margin of error the robustness of schemes it, but no so much the one of some components.

Affirmed that they exist still uncertainties in the modelado FEM of the behaviour/behavior of the exact dynamics of a machine and that is advancing a lot in the simulation of the behaviour/behavior of the husillos to balls. Likewise, reflexionó around how much it is necessary to deepen in the software of simulation and asked if in occasions suits to analyse/analyze a physical model.

The chatter can solve from the process, from the design or from solutions of control

In his intervention, Jokin Muñoa (Ideko IK4) spoke of the chatter in the operations of mechanised/mechanized, a “almost only vibration, a real problem that can limit a lot of processes of mechanised/mechanized”. The majority of the cases of chatter produce because of the effect regenerativo. The chatter can solve from the process (for example by means of the selection of conditions by means of lobules of stability in which they influence the dynamics, the geometry of the tool), from the design (devices of amortiguamiento, for example in the tool, or by means of an amortiguador passive external, or increasing the dynamic rigidity) and from solutions of control. The greater part of his presentation treated on this last possibility. It concluded signalling that, depending of the process of mechanised/mechanized, a solution can be better that another.

general Sight of the inaugural day.

Pat McKeown (Cranfield Precision) Centred/Centered his presentation in the engineering of ultra precision, a discipline based in the application of the metrology (dimensional and thermal) to the production, and that refers to materials, mechanised/mechanized and processes of manufacture, design of machines of precision and mecatrónica, servomotores and actuators. As it said, the start in machines of ultra precision bases in the cut in the field of the nanotechnology, a field in which in United Kingdom presented does already years the machine Nanocentre, “the most precise in this field and still current although it was developed in 1990”.

Good part of his conference devoted it to the manufacture of optical systems of ultra precision, and mentioned like different examples telescopes of last generation of spectacular dimensions composed by more than 900 segments that have to be ultra precise, as well as the paper in his manufacture of the rectificadora Cranfield University BoX Machine.

José Ramón Rivero, of BTI Biotechnology Institute, spoke of the manufacture of equipment and medical devices and exposed three real cases in which the technologies of Ideko have served to BTI, a company with diverse activities, between which finds the manufacture of dental implants, prothetic components, instrumental surgical, teams electromédicos and software medico. The three cases were: thermography (for predecir better the fatigue of the implants), photogrammetry (to measure the position of the implants and reduce the steps until the final solution of the patient, deleting the posicionadores physical) and the capacity of prototipaje.

Alberto Mendikute (Ideko IK4) – exposed the advantages of the optical technicians for the measurement, adjust and placing of pieces in machine and the reduction of the time of alineación of a piece of big dimensions.

The presentation of Jorge Posed, director attach of Vicomtec IK4 turned around the virtual reality and increased in the industrial surroundings. It explained how at present the maintenance and the conceptual design take advantage of of these technicians and presented examples the aesthetic visual configuration of cabins of elevator and the visualisation/visualization of a plant of enormous dimensions, obtained so alone from data of CAD.

The improvement of the processes of manufacture, the tendencies in the aeolian energy (Gamesa), the optimisation/optimization of processes of rectified, the mechanised/mechanized of titanium, the materials used in aeronautical (ITP), the laser cladding and the manufacture of pieces of composite completed the day.
