The Department carries out scientific and research work in the field of manufacturing techniques (mainly cutting), machine tools and systems, and production automation. At present, scientific and research work is directed towards computer integration of all activities in the technological process of a product in the following areas: computer-aided selection of tools and cutting conditions, optimisation of machining processes, diagnostics of the surface layer of workpieces and the condition of tools, programming of computer-controlled machines, construction of special tools, development of unconventional technologies, measurements of geometric values.
Since its inception, the Department has undergone comprehensive development. The Department's equipment was expanded to include modern research devices. The Department's scientific profile was adjusted to the implementation of new research directions and to the needs of industry.
The scientific and research work of the DMTA focuses on the following areas:
1. Studies of physical phenomena accompanying the cutting process (forces, vibrations, acoustic emission, temperature in the cutting zone).
2. Surface engineering (modelling, manufacturing, measurements and evaluation of shape, topography and physical properties of surface layers of shaped products).
3. Tools and tooling systems (design, FEM analysis, machining programming and manufacture of special tools)
4. Machining of hard-to-machine materials (turning, milling, electrical discharge machining, machining process optimization)
5. Metrology (measurements of geometric quantities including coordinate measuring techniques, and research on computer aided measurement and automation of measurements)
6. Mathematical and numerical modeling of phenomena occurring in machine elements and technological processes.
7. CAD/CAM systems integration (modelling, simulation and optimization of production processes with respect to machining stability, cost and production time)
8. Machine control (applications of PLC and CNC controllers in technological machines and manufacturing equipment)
9. Modelling, programming machining and manufacturing of components on 5-axis machine tools, especially for the aerospace industry (complex surfaces, hard-to-machine materials, geometrically complicated machine parts).
