Opis:
One of the basic trends in the automotive industry today is to achieve the most acceptable ratio between the total weight of the car to its overall performance and utility properties. Reducing the weight of cars is largely due to the use of new materials, where composite materials offer a wide space for their application. Composite materials have their specific properties which is very beneficial in reducing the total weight. Another advantages is strength, stiffness, low fiber density, the ability to form them into any shape based on the required applications. One of the challenges associated with the use of composite materials is the search for new technological possibilities of joining composite materials with metals. These include technologies as for example riveting, ultrasonic welding, but especially gluing. Bonding is currently one of the most preferred ways of joining composite materials. The paper deals with testing of technology of bonding composite materials with metals used in the manufacture of automobiles and a comparison of individual results obtained from the experiment.

Opis:
This paper deals with the design of an automatic robotic assembly station with the aim of creating a new and more efficient working environment in the production process on the assembly line and thus contributing to meeting customer requirements. The paper presents theoretical knowledge on innovations and on the innovation process. The introduction of an automated workplace will lead to a higher production line than it follows from evaluation of data collected over time. The result of the work is a proposal to create a new and more efficient work environment

Opis:
During mechanical disintegration of the rock, for mining works are used also roadheaders. Roadheaders, in comparison with disintegration by blasting operations can without interuption, and works changes with one machine, dissolve, load and at the same time mine disintegrated rock. These electro-hydraulic machines cause no harmful vibrations and are ideal for mining coal and other soft rock minerals. Mechanical mining is safer, protects the rock environment, allows mining without further breaks, allows you to achieve a higher level of daily progress and also saves work. The analysis of occupational accidents in the Slovak Republic shows that it is necessary require from employees increased attention in any work activity and attention in the work performed (mainly work in handling material, objects and burdens). In the underground coal mines further attention needs to be paid to securing hazardous areas, it is necessary to proceed in such a way as to prevent as much as possible the fall of rock as much as possible Underground roads require modification and equipment in accordance with regulations. It is necessary to follow health and safety instructions mentioned in operating and maintenance documentation. Correction of some deficiencies is ordered by a decision of the Mining Office. Most measures are aimed at adhering to technological discipline, to complement operating documentation, to prevent rock falls, to equip some machinery and transport equipment, to work procedures for handling loads, to maintenance of mining works and for explosion and anti-vapor prevention. In this article, we assess the safety risks of two roadheaders for coal mining works in Slovak conditions. Pairwise comparisons of the criteria of selected roadheaders were used to determine the safety risks, as well as taking into account the risks and safety measures according to the mixed methods following to the standard.
