Gheorghe, Ion Gheorghe ; Badea, Florentina

1. INTRODUCTION

The new concept of integrative mechatronic microengineering used in the intelligent manufacture and automation, refers to the synergistic integration of engineering / mechanical precision micro-engineering with other high-tech fields as electronics engineering and computer engineering in the design and manufacture of intelligent products and systems with self adaptability, flexibility, speed work and high decision-making mix with high intelligence and informatization.

The concept approached by the author addressed the use of systemic integration of systems / micro-systems, sensor architecture and actuators, controllers and processors, in the complex processes of programmability, interactive communication, self adjustment, self diagnosis and simulation.

New concept, created by the author, has as main objectives:

* improving and upgrading systems / products and processes;

* computerization and simulative guiding of system functions and communications and interactive dialogue;

* self diagnosis of states and functions in the complex matrix system and the intelligent and automated process;

* addressing system techniques in information processing and control decision;

* modular and integrated design of actuators, mechatronic technology devices, hardware system design, intelligent controller, sensor architecture, smart mobile effectors, intelligent electronic units, computer units and software process in an inclusive construction of the overall system structure and new generation on levels of processing and logical decision;

The new concept and systemic and synergistic vision regarding integrative mechatronic micro-engineering used in intelligent manufacturing and in automation, are exemplified in the paper, with practical applications in manufacturing processes and the processes of measuring, adjustment, control and monitoring, setting out the future of HIGH -TECH domain, for a new computerized and globalized industry.

2. CONCRETE APPLICATIONS OF INTEGRATIVE MECHATRONIC MICRO ENGINEERING IN INTELLIGENT MANUFACTURING AND AUTOMATION

2.1 INCDMTM Philosophy

(National Institute of Research and Development in Mechatronics and Measurement Technique from Bucharest Romania), identified in the mix of new adaptive and generative engineering concepts and techniques (Gheorghe, 2006).

The essence of "INCDMTM philosophy" synthesized in the Triad Research--Manufacturing--valorification is identified by:

* capacity, competitiveness and reliability;

* real innovative and effective contributions;

* high-tech mechatronic systems and equipments;

* maintenance, traceability and dependability;

* accuracy, reliability, and resolution;

* hardware, software and computerization;

* assessment, diagnosis, monitoring and decision;

The mix of new adaptive and generative engineering concepts and techniques (Bharat, 2007), (Gheorghe, 2005) is based on the accumulation of new knowledge and discoveries, interactive communication, organic and synergetic integration of components, products and systems, modeling and simulation, expertise and self diagnosis, self-adjustment, management and decision.

2.2 INCDMTM concept of intelligent integrated technology

Elaboration of integrated mechatronic intelligent technologies through the concept "philosophy INCDMTM" based on the mix of new engineering concepts and techniques and adaptive system, based on specialization "mechatronist engineer" now, and/or "integronist engineer" (Gheorghe, 2006) for the future, training started in Romania in the years 1996, although in the world market, it started in 1978 (in Japan).

Therefore, the concept of "INCDMTM philosophy" of making intelligent mechatronic technologies, involves in an engineering structure, synergistic combination and integration of engineering/precision mechanics micro-engineering, through mechanical/micro- mechanical systems/micro-systems, components and technological devices, the execution, elements, sensors/micro-sensors, transducers/micro-transducers, etc., electronics by integrated circuits/micro-circuits, electronic systems/micro-systems, etc., by electro-techniques by electric engines/micro-engines, actuators/micro-actuators, electrotechniques elements/micro-elements, circuits / and information systems/ computing microsystems, processors/ microprocessors, controllers/ microcontrollers, softwares, etc.

This complex structure (Gheorghe, 2005), is made logic and integrated depending on the type of technology/ micro-nanotechnology required by manufacturing processes and conceptual installed in real modulation schemes in accordance with fig.1 to be developed systems/ equipments and technologies/ mechatronic intelligent micro-nanotechnologies with concrete applications in industry.

The concept "philosophy INCDMTM" of making integronique intelligent technologies (Gheorghe, 2006), implies in a vision similar to mechatronics, a complete integronized engineering structure of several areas, both technical and scientific areas and exact sciences, social sciences and humanities, in a systemic integrated and synergetic apprehension, cumulating constructive and functional solutions.

Micro-Nanotechnologies for intelligent control of surface topography are developed through intelligent equipments type "Form Talysurf 120 Taylor Hobson" (Fig.2.), special software for ultraprecise determinations of the surfaces roughness (microgeometry), shape (macrogeometry) of revolution surfaces, of areas liniarity/ perpendicularity and parallelism and high metrological characteristics, such as high-resolution on Z axis (about 17 nm), detector high-resolution (about 8 nm/ 0.5 mm), areas of measurement [for x, z: 120/28 mm (for contour) for x, z; 120/1mm (for roughness)].

Maximum error of intelligent mechatronic equipment presented was metrologically determined in the following value matrix:

Maximum error: 0.05[micro]m Maximum uncertainty: [+ or -]0.025[micro]m

3. CONCLUSION

Mechatronics integrated microengineering used in the intelligent manufacture and in automation, is based on the mix of new engineering concepts and techniques adopted and generational, containing for each specific intelligent mechatronic equipment presented, intelligent systems and subsystems, with appropriate functions, as follows:

* systems / subsystems and components of high precision micro-nanomechanics microengineering [microconductors / microsensors / etc.];
