Meet the editors

Ľubomír Šooš is currently the Dean of the Faculty of Mechanical Engineering at the Slovak University of Technology in Bratislava. His professional background is in the theory and design, especially of machine tools and equipment for machinery production. Until now he has published more than 295 scientific articles in journals and is the author of 52 national and international patents. As a leader he participated on 49 international and

national research projects. He is a member of several editorial boards of the international scientific journal "Manufacturing Technology", "Praise Worthy Prize", "MM Science", "Waste Management Forum" and others. Professor Šooš has achieved very good collaboration with the industry. He is also Vice-President of the Automotive Industry Association of the Slovak Republic. For his excellent cooperation he received the "Award of Rector TU" Novi Sad (Srb), Award of FME CVUT(CZ), Medal of Georgia Agricoly in Ostrava (CZ), "Professor of the year 2015" (SK) and his Doctor honoris causa on TU Ostrava (CZ).

Professor Marek worked as a Technical Director at TOSHULIN and TOS Kuřim - OS company from 2000 to 2016. Now he is a lecturer at the Technical University in Brno, Faculty of Mechanical Engineering, Institute of Production Machines, Systems and Robotics of Engineering. In his practical and pedagogical activities, he aims especially at design of machine tools and machining centres for rotary and non-rotary workpieces, at theory of the

designing process and of the product life cycle, and last but not least, at system methodology. He is a member of many professional institutions and works as a member of the managing committee in the scientific section of the magazine MM Science Journal.

Preface

You have just opened the book "Machine tools - design, research and applications". Machine tools are systems designed to create workpieces of a particular shape, dimension and machining quality. For this purpose machine tools have to create cutting motions that consist of the mutual coupling of vectors of rotary motion and translational motion. Today, we encounter machine tools everywhere and we

An important role in the development of today's type of machine tools was played by the rolling bearing patent obtained by the Englishman Philip Vaughan in 1794 and, three years later, by the rediscovery of the lathe by his compatriot Henry

The development and application of new, highly productive cutting tools made of cutting ceramics, natural or synthetic diamonds and other synthetic super hard materials allowed a significant increase in the values of cutting speeds. The pioneer of high-speed machining is considered to be the German researcher Carl Salamon, who in 1920 milled steel at the cutting speed of 440 m.min−1, and aluminium at up to 16 500 m.min−1. This significantly reduced overall machining times, increased

The productivity of the machine tool is characterized by the number of manufactured parts along with the size of the machined area and the volume of material used. Productivity is limited by the mean thickness of the chips and it depends on cutting and feed speeds. Moreover, the cutting speed depends mostly on the frequency of rotation of the headstock of the machine tool. This is the reason for the ongoing increase in mean revolution frequencies, the ever more frequent application of headstocks with integrated drive, the so-called "Electro-spindle"

In proportion to the growth of living standards, the speed, quantity and variety of requirements for the quality and accuracy of manufactured products have increased. The means to achieve the required accuracy of the machine tool is by

Therefore, in addition to increasing the productivity of machine tools, it is of the utmost importance to pay special attention to optimizing the design of the machine in terms of rigidity, thermal expansion, variability and chip removal at large volumes of machined material. Therefore, when designing and optimizing the construction of machines, we increasingly resort to virtual prototyping and computer analysis of the functional properties of the proposed machine.

The basic condition for achieving the required machine tool accuracy, as well as that of the machined parts, is the rigidity of the "machine - tool - preparation workpiece" system. Apart from rigidity, this system is influenced by the geometric
