Summary

Cílem předmětu je seznámit studenty s teoretickými i experimentálními způsoby popisu typických rysů zanechaných stopami flexibilních paprsků na materiálu, se způsoby kompenzací a simulacemi těchto kompenzací. Hlavním přínosem by mělo být praktické seznámení se studentů s negativními rysy práce flexibilních nástrojů, naučit se předpovídat jejich velikost podle typu materiálu, jeho rozměrů, rychlosti opracovávání materiálu a dalších faktorů. Student by se měl naučit posoudit, zda bude pro řešení problému vhodný teoretický nebo experimentální přístup, zda je možno potřebnou přesnost dosáhnout použitím kompenzací, nebo je daný flexibilní nástroj pro aplikaci nevhodný z důvodu nemožnosti realizovat požadované zadání, z důvodu enormních nákladů, ekologické zátěže, apod.

Subject syllabus:

1. Analysis of physical reasons for changes of flexible tool trajectory direction during penetration through material. 2. Physical description of jet trajectory using material and tool properties. 3. Determination of the key parameters influencing trajectory of the given tool type (laser, plasma, liquid jet). 4. Determination of the two basic deviations of the trajectory by penetration of the tool through material – divergence and delay. 5. Determination of the necessary compensations from theoretical models of tool operation. 6. Determination of compensations according to experimental results, determination of typical shapes for calculations of compensations. 7. Analysis of the relation of compensations on machining factors - dynamic modes of changes.
