| Summary |
|---|
| The main goal of the subject is to present students three basic progressive technological tools for material disintegration. These tools are used for machining of materials resistant to machining by conventional tools, penetration to great depths in materials and further special operations on materials. These tools are laser beam, plasma jet and liquid jet. Beside these three technological tools students are acquainted with other machining tools. This subject introduces students into problems of improvement of progressive technological tools for materials disintegration and diversification of their application possibilities. Students are acquainted with principles of tools generation, their basic characteristics, physical base of impact on matter regarding its state, basic principles of power and efficiency determination. |
