About the book


The book is a compendium of engineering knowledge in the field of construction and operation of CNC machine tools, which are the basic production machines in the machine industry.
The author presents in it:

  • development trends of modern machine tools, foundations and examples of modular construction and basic properties of machine tools,
  • technical solutions and construction of the most important assemblies and components: bodies, guide connections, main and feed motion drives, sensory systems, pallet and tool coding systems,
  • structure and operation of modern numerical control systems in the function of performed tasks, architecture and topology of computer industrial networks, allowing to combine control systems,
  • characteristics of four basic groups of CNC machine tools: lathes and turning centers, milling machines and milling centers, grinding machines and machine tools implementing hybrid manufacturing technologies,
  • basic information on the automation of manufacturing and flexible machining systems,
  • research issues, methods of diagnostics, modernization and selection of machine tools.

    The manual allows you to familiarize yourself with technical solutions, construction and basic problems that determine the decision to invest in numerically controlled machine tools, their operation and possible modernization.
    The book is intended mainly for students of technical universities who study mechanics and machine building as well as automation and robotics, in specialties related to machine tools, machining technology and automation of production processes. It will also be useful for mechanical engineers and automation specialists who deal with the issues of technology implementation in the field of machining processes on machine tools and automation of manufacturing processes.
