The article deals with the assessment of the suitability of the manufacturing process and the analysis of the gear runout. The measurements were carried out using the 3D measuring device Wenzel WGT 280. The Palstat CAQ software was used to evaluate the process, while control charts for individual values and the sliding range were applied. The average value of the process reached 0.1460 and the sliding range was 0.00409. The suitability of the process was assessed using the Cp and Cpk indices with a required value ≥ 1.33, while the calculated values were 1.47 and 1.34. The results confirm that the monitored process is suitable. Subsequently, a comparison of the runout before and after heat treatment – nitriding was performed. The specified tolerance limits (0 μm to 0.0320 μm) were not exceeded, which confirmed the satisfactory state of the process even after the treatment.

In the industry, the concept of “production quality” means a very important and inseparable role, which has a large share in the final quality of the product. Various factors affect product quality. Above all, state-of-the-art technologies are used in every industry, which helps to adapt quickly and efficiently to changes in market conditions, which has a significant impact on the competitiveness of manufacturers to become market leaders. The manufacturers ‘efforts are made to produce a flawless product that will excessively meet customers’ requirements for the perfect product. An integral part of the production process is the quality control of products at certain stages of production. Measurement requirements are defined by satisfactory accuracy, variability, total cost and speed. An important factor in product inspection is currently the creation of a three-dimensional virtual model of a real product, where you can easily compare the created 3D model with the original CAD model and display dimensional deviations.

In the last ten years, the development and implementation of robotics, sensor and digital technology in the world from introduced us the third industrial revolution to the fourth industrial revolution. In its development strategy, Germany introduces digital technologies in production processes called “Industry 4.0” in 2011. The German example is followed by the following countries: USA, Great Britain, Sweden, Japan and other. Almost all technologically developed countries strive to introduce advanced technologies into production processes in order to maintain their competitive positions in the market. The implementation of the fourth technological revolution depends on a number of new and innovative technological achievements, i.e., the implementation of patents for the basic technologies of Industry 4.0. It is necessary to integrate production processes in all phases of product development, as well as monitoring during its working life through the use of advanced technologies. When automating production processes, we must include intelligent sensors, intelligent robots and connect everything to the Internet using digital technologies that closely monitor the product development process. It is also required to collect large amounts of data through network communication used during the production process. The paper presents a structural network with all levels for the implementation of Industry 4.0 in the production process of the metal industry.

The purpose of this publication is to elucidate the nature of radical innovations as drives of various industrial revolutions, as well as the conditions that led to their emergence. They incorporate substantially different technologies from existing ones and meet the needs of consumers in a new way and better than the current ones.
This article will discuss factors that can be used to evaluate an innovation as radical. A new view of Industrial Revolution will be presented, explaining critical factors and their relation to sectors of production. An invention may lead to the production of a new, unknown product at a certain time or to the provision of an unknown service. The use of these unfamiliar products or services on the market is characterized as a radical innovation. Relevant radical innovations in turn lead to industrial revolutions. It is argued that a paradigm shift takes place and we call it Industrial Revolution.

Risk management constitutes currently one of the most important elements of the management of an enterprise, which is crucial to its security and continuous improvement. This is a several-stage process, and its implementation should systematic and principled in character. The article sets out the risk assessment for activities performed in conjunction with individual operations of a manufacturing process, and specifically, the book production process. The risk assessment was preceded by the identification of hazards to technological, transport and control operations, followed by their analysis using an indicator method. Operations have been identified, which are characterized by the highest risk, and preventive and prophylactic actions using various control measures (technical, organizational, legal, individual and collective) have been proposed. Risk assessment for a task is a primary outline for the use and implementation of risk management issues that go beyond the commercial risk assessment in an enterprise.

This article is related about contemporary concepts applied in automation machinery’s design and its ability to be implemented in production process. In this direction meaning of automation has been expanded, a new concepts and connections have been defined. Entire technical equipment in automation system is defined, and arise the chance for widening of this process.

There are a few examples of author’s design and implementation of automation machinery and how they participate in the system “automation”
