The term "INDUSTRY 4.0" or "fourth industrial revolution" was first introduced at the fair in 2011 in Hannover. It comes from the high-tech strategy of the German Federal Government that promotes automation-computerization to complete smart automation, meaning the introduction of a method of self-automation, self-configuration, self-diagnosing and fixing the problem, knowledge and intelligent decision-making. Any automation, including smart, cannot be imagined without industrial robots. Along with the fourth industrial revolution, ‘’robotic revolution’’ is taking place in Japan. Robotic revolution refers to the development and research of robotic technology with the aim of using robots in all production processes, and the use of robots in real life, to be of service to a man in daily life. Knowing these facts, an analysis was conducted of the representation of industrial robots in the production processes on the two continents of Europe and Asia /Australia, as well as research that industry is ready for the introduction of intelligent automation with the goal of establishing future smart factories. The paper gives a representation of the automation of production processes in Europe and Asia/Australia, with predictions for the future.

In 2010 German government continued with the strategic plan named „‟High-Tech Strategy 2020‟‟ with an emphasis on scientific and technological development. Under the title „‟Industry 4.0‟‟they are promoting reform and modernization of production in all industry branches by introducing digital technology, which depends on a number of new and innovative technological achievements. Their intention is to integrate production processes at all stages of formation and use of the product with the use and application of ICT and digital technology. The modernization and automation of production processes include advanced sensors and intelligent robots configured independently so as to monitor and participate in the development of products. In addition, technologically advanced countries like USA, UK, Japan, Sweden and others have accepted and introduced digital technology in production processes with the aim of creating intelligent automation, and intelligent factory of the future. China is faced with competition from ASEAN countries and Central Asia, which have cheap labour market. This weakens the export demand from China to the EU and USA, as evidenced by the „‟Report on the Global Innovation Index 2015‟‟.In response to the „‟Industry 4.0‟‟, the Government of China created the strategy „‟Made in China 2025‟‟, which promotes the relationship between information technology and industrial production, introduces the optimization of production processes, increases the ability to innovate in the industry including ICT, industrial and service robots, high technology machine tools, new materials, etc. China is relatively weak compared to the technologically developed countries in the world in regard to innovation and newer technologies, so it focused on industrial modernization in key sectors: telecommunications, production of commercial aircraft and helicopters, agricultural machinery, medical devices, alternative energy, electric vehicles and materials. The implementation of the adopted strategy in China is creating new opportunities for the promotion of successful innovative and creative economy, which enables the transition from „‟Great industrial economy‟‟ into „‟Powerful industrial economy‟‟.

The world’s largest user of industrial robots in production processes is automotive industry, because global competition in the market requires continuous automation and modernization of production processes in the automotive industry. The use of robots in the world is continuously increasing year by year, so it is expected that about 414.000 robot units will be used in 2019. China is the first country in the world in the application of industrial robots, and is increasing the use every year, so that we can say that the annual trend in the application of robots in China is exponential by function. The leading countries in the application of industrial robots, in addition to China, are: Republic of Korea, Japan, North America (USA) and Germany. The tendency of application of industrial robots in the automotive industry in the world is growing on annual and total level. High application of industrial robots in China has resulted in the development of the automotive industry. The estimate is that in the future China will become the largest user of industrial robots, meaning that China is planning to implement the modernization and automation of production processes in the automotive industry, but also in other industries including electronics industry, metal industry and plastics and rubber industry. The development of new technologies and innovations is leading to the development of robotic technology which has been increasingly used in the automation of production processes. This will, in return, lead to the development and application of "smart automation" or "smart factories" in the future that will, besides vehicles, also produce other high quality products in short time period and with large varieties.

The main goal of this paper is to get a mathema-tical model for the process of deep drawing force with the reduction of wall thickness. Mathematical model should have a correct analytic description of this deformation process and along with that a possibility to calculative deep drawing force and after that a possibility of optimization of the whole deformation process and force. In this paper experiment planning is presented, from defining significant factors (parameters), levels of variation, equipment for experiment performing, processing of receiving results with known analytic models and on the end structuring final mathematical model for deep drawing force.

Laser welding is becoming an essential procedure in Automobile industry. Compared to standard welding processes such as MIG/MAG and point welding, laser welding has distinct advantages, such as small strains, higher speed of welding, quality welds as well as high flexibility.These advantages are crucial in modern automo-bile industry since the quality and flawless accuracy of load bearing welds ensures safety and thus competitiveness of the final product. High welding speed and short cooling periods of the weld additionally increase productivityThis paper is a presentation of a simulation indus-trial robot laser welding of load bearing construction in automated production process. 3D simulation play very important role in robotics development. Today we can simulate every production process segment by using IT tools. This simulation process enables to develop new pro-duction processes with minimal costs.

Energy stability and security have become one of the most important issues in recent years on planet Earth. Nowadays, worldwide economic, industrial and social development is related to the energy and energy-system that provided great benefits to a society, but the society is paying a high price because of the production and emission of carbon dioxide and other greenhouse gases into the atmosphere. There are numerous climate changes, which pose a threat to each continent, disorder in agriculture, disorder in food production, floods and fires, as well as changes in the ecosystem. Energy stability and security have become one of the most important issues in recent years. Energy is essential for development of any country, notably when it comes to its industry and economy. Without adequate policy operations of the energy sector, it is not possible to achieve industrial or economic progress. Nevertheless, no matter how important energy is for the development, it is only a mechanism for achieving the ultimate goals – sustainable economy, clean environment, high standard of living, prosperity and health of the population. This paper elaborates on and outlines a strategy for energy development of renewable energy sources in the world, as well as in the European Union. It presents in great details the application of new technologies that have led to the development of renewable energy sources: wind-power, solar energy, small hydro power plants, biomass, and their increase in the overall participation of energy production and reduction of fossil fuels in energy production. Investing in new technologies which use renewable energy sources have led to the increase in employment in the world, so that about 6.5 million people in the world have been employed until today. This paper outlines the trend of increasing energy production from RES (renewable energy sources) by investing in any of the abovementioned energy sources, as well as employment for each energy source in the world and the EU-28. Also, the development of renewable energy sources in the future has been presented.

Planning of the modern manufacturing systems that would be suitable for the most demanding cutting processes requires analysis of all technical and technological process parameters by applying scientific methods, modeling and optimal conditions of machining process and systems defining. In order to secure the planned functioning of machine tools they need to be sufficiently resistant and stable at all influences which are exposed in the cutting process. Because high number of influence factors to the cutting process, it is very difficulty to determine most influence parameters of the cutting process by analytical model. For this reason it is necessary to apply the experimental measurements and analysis of the results which will be used for creating fudantion for cutting force identification and which is indispensable in the development of new machine tools and improving existing machining systems. Objective of this paper is to find mathematical algorithm of tool holder acceleration aNA = f(σz, v, δ) in function of machined material strength, cutting velocity and depth of cut. Experimental investigation of tool holder acceleration during turning process has done for three different types of steel: 9SMn28, S355JOG3 and C45E.

Industrial branches where the changes occur with the introduction of the new technologies in a very short period are automobile and aviation industries, because the securing and ergonomic criteria had to be achieved. These demands initialized setting of the new productive philoso-phy, which is based on a modern production like plastic forming and modelling with an incompressible fluid. A tube hydroforming got a significant role in the last five years and is considered as a technology of rapid development. This paper provides researches and analyses of hydroforming of thin-walled tube elements. A work-piece and die contact for hydroforming in a work process manifests with the friction force which has an influence on: axial force, axial punch feed and workpiece wall thick-ness. The stress-strain state and their disposition during the tube hydroforming are foundation where the friction influence in tube hydroforming is based on. It provides an analysis of deformation zones and friction in T shape tube hydroforming. An analytical model of friction coefficient change in hydroforming between a tube and die has been carried out. The main objective of this paper is to suggest new analytical model for friction coefficient determination in hydroforming of thin-walled tube elements which de-scribes process the most realistically. This paper provides an experimental way of needle sensor setting in measuring of the contact friction in T shape tube hydroforming. DOI: http://dx.doi.org/10.5755/j01.mech.19.6.6012
