This paper describes a novel quartz crystal sensor for measurement of the density-viscosity product of Newtonian liquids. The sensor element consists of two piano-convex AT-cut quartz crystals vibrating in a thickness-shear mode with the liquid sample in between. This special set-up allows suppression of disturbing resonances in the liquid layer. Such resonances are generated in the common single-plate arrangements due to compressional waves caused by spurious out-of-plane displacements of the shear vibrating finite plate. The primary measurands of the sensor are the fundamental resonance frequency and the associated resonance Q-value, which are influenced by the viscously entrained liquid contacting the quartz surface. The sensor allows the measurement of samples with viscosities from almost zero (air!) up to 200 cP with a sample volume of 130 microl.

Over the years, the world of manufacturing has witnessed significant work in the area of Intelligent Manufacturing. Special efforts have been made in the implementation of new technologies, management and control systems, among many others which have all evolved the field. Closely following all this and due to the scope of new projects and the need of turning the existing flexible ideas into more autonomous and intelligent ones, i.e.: Intelligent Manufacturing, the present paper emerges with the main aim of contributing under a this new intelligent denomination to the design and analysis of the material flow in either systems, cells or workstations. For this, besides offering a conceptual basis in some of the key points to be taken into account and some general principles to consider in the design and analysis of the material flow, also some tips on how to define other possible alternative material flow scenarios and a classification of the states a system, cell or workstation are offered as well. All this is done with the intentions of relating it with the use of simulation tools, for which these have been briefly addressed with a special focus on the Witness simulation package. For a better comprehension, the previous elements are supported by a detailed layout, other figures and a few expressions which could help obtaining necessary data. Such data and others will be used in the future, when simulating the scenarios in the search of the best material flow configurations.

Abstract. The contribution is focused on the creation of an idea proposal and simulation of the assembly system in cooperation of the human and the industrial robot. The aim of the research is to verify the feasibility of this cooperation between the human and the industrial robot on the basis of the created simulation in the assembly process. The important step of the design this collaboration is the determination of rules and safety of this cooperation. The paper also presents the method of working with the selected software and its functionalities and sequence of steps at the simulation creation. The objective of the research is the evaluation of the idea proposal of the collaborative assembly system on the basis of the created simulation. The analysis and evaluation of the simulation confirm the feasibility and safety of the cooperation of the man and robot and also verified the possibility of assembly made by man and robot from the disposition and dimension on point of view of the proposed workplace.

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 tools integration of the virtual CAD models into programming environment. Offline programming carries a lot of advantages for example 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.

Abstract. Nowadays the trends in manufacturing are aimed at exploding and using the full potential of production devices and systems. In this context, Simulation and VR tools play a key role in the evolution of such systems specially if used in conjunction. By using these tools, the present paper focused on the analyses of an iCIM 3000 system. The main goal of the paper lied on studying the possibilities of increasing the efficiency and effectivity of whole system and its individual devices. This was achieved by means of the creation of simulations and their comparison to the real system. At the same time, the results of the simulations themselves also became the basis for further and richer analyses by means of the use of VR tools that allowed a much deeper and detailed take of the whole system. The use of VR tools offered a better assessment and comprehension of the system under study what at the same time also worked as a feedback for the improvement of the initial simulations, and this by eliminating and/or improving unnecessary movements and collisions. The results of this study have a positive significance in the improvement of the system once these are implemented.

Flexible manufacturing systems enable rapid changes in production. These changes may be due to changes in the product itself, such as different variations of the product or changes in conditions in the production itself. Currently, most products are designed on a computer using a variety of CAD software. Using sophisticated CAD tools, the resulting 3D product model can include not only the geometric product data but the process plan and technology data. Group technology is very often used to quickly create a technological process. Where, based on similarity, parts are assigned to individual groups and each group has the same basis for the technological process.
