The Possibilities of Increasing the Flexibility of Intelligent Assembly Cell

In relation to how the complexity of modern assembly technology increases, requirements for precise, fast and relevant information specifically for the assemble process also increase. Automation allows the fast and precise measurement of various parameters, assessment of the values obtained and the implementation of the required measures in real time. Automation tools allow evaluation, parameter measurement, comparison and application via computer technology and various software resources. One of the aims of the VEGA 1/0206/09 Intelligent assembly cell project solution as per our institute is the creation of a means of forming assembly cells, their duly defined critical placements, verification of the assembly process as a dynamic system of consistency from a technological, handling and control sub-system point of view via means of 3D models in CATIA environment software. Authors of this paper are members and experts of project group (VEGA 1/0206/09) interested in robotics, manipulators and technological devices. Whereas mechanical production trends in the 21st century tend to focus more on resilience and flexibility, the authors of this article have taken into consideration the possibility of re-evaluating the above-mentioned data — which is an essential element in terms of raising flexibility, thus definitively contributing to increased competitiveness.Copyright

Intelligent Clamping Fixture in General

The majority of actual production are small or middle batch character. Thence, using of flexible production systems has lot of advantages. Their new generation fixture devices different from classical fixtures not only by design but also by its properties. One from the ways of supplementary time reducing is an suitable fixture using and supplementary operations automation. Using of proper fixture will increase the production quality, the productivity and reduce the production costs. The fixture provide clamping of workpiece on machine desk, so as the workpiece have the right position toward tool. This position must be retain in machining time too. The fixture design are dependent on the batches of production. In small batches we use the fixtures designed from modular system and in large batches we can use the dedicated fixtures. Their new generation fixture devices different from classical fixtures not only by design but also by its properties. In standard production are mechanical peripheries (for example fixtures) controlled and monitored by operators. In automated production must these mechanical peripheries working in automated mode too. In time of work cycle these devices works automatically, without operator intervention and cooperate with other devices of production system.

On the possibilities and the advantages of robot off-line programming Teaching of off-line programming methods as a tool to further industrial implementation utilization

Current trend in automation area is focused to the innovation in all fields of the technologies and technological devices. Probably industrial robots and manipulators belong to development too. Industrial robots and manipulators belong to progressive elements of automation. Modern concept uses the offline programming as a tool integration of the virtual CAD models into programming environment and implementation to the education process. Offline programming carries a lot of advantages such as possibility of the programming without real robot system, possibility of the collision state debugging. Implementation of CAD models in virtual environment of Robot studio achieves better workplace station of creating robotic system and also it generates rather trajectories of the robot path in this system.

Incorporation, Programming and Use of an ABB Robot for the Operations of Palletizing and Depalletizing at an Academic Research Oriented to Intelligent Manufacturing Cell

The current trend of the final product quality increasing is affected by time analysis of the entire manufacturing process The primary requirement of manufacturing is to produce as many products as soon as possible, at the lowest possible cost, but of course with the highest quality. Such requirements may be satisfied only if all the elements entering and affecting the production cycle are in a fully functional condition. These elements consist of sensory equipment and intelligent control elements that are essential for building intelligent manufacturing systems. Intelligent manufacturing system itself should be a system that can flexibly respond to changes in entering and exiting the process in interaction with the surroundings. Philosophy that we apply to solve the problem rise from intelligent assembly cell by building on our institute of manufacturing systems and applied mechanics Essential philosophy is integrate of interconnection between palletizing- depalletizing robot and Intelligent assembly system by the means mobile robot Robotino.

Selection of the Appropriate Type of Sensory Equipment

In this contribution is presented the method of choice of the right sensor. The selection of appropriate sensory equipment means a completion of requirements. Unfortunately, very often these requirements are not exactly known or detail. The first issue of designer is to get the most information about future applications of measuring device, all appropriate conditions of operations, etc. The short list of requirements should be the most detailed.

Virtual Laboratory of Pneumatics Systems Building

Virtual laboratory of pneumatic and electro pneumatic systems will be used for learning of pneumatic and electro pneumatic schemes design principles. Rapid changeable conditions on labour market are on one side connected with international countries integration and on the other side the conditions are connected with rapid technological development. These changeable conditions are so creating new pressure to the employee competitions. Labour power is an important development aspect of present day informatics society. This importance can be found on firm level as well as in global economic development use. Labours which are suitable and high qualified for these conditions can be found in groups of university educated graduates. Especially we are talking about graduates of economy and technical universities. This kind of graduates is very required on the labour market. Researches operating about employers requirements and also operating about student opinions to the university training are indicating that teaching schedules and education process are not creating for praxis requirements. That mean, that universities have to teach special practical knowledge and skills re-bound to the praxis and its needs.Copyright
