PT Journal AU Palascakova, D Demec, P TI Working Precision of the Machining Centre SO Acta Mechanica Slovaca PY 2018 BP 54 EP 59 VL 22 IS 2 DI 10.21496/ams.2018.018 DE Virtual reality; FEM; parallel milling; opposed milling. AB The aim of the article is to analyse the precision of the machining centre using numerical and experimental quantification. The identification of the effects of the machining process itself as well as the impact of machine design features will allow it to predict and subsequently optimize its construction in terms of its working accuracy. Measurement of dynamic forces and geometric tolerances was also carried out. The practical importance of virtual machining is primarily the reduction of financial costs and acceleration of machine design without the need to produce a physical prototype. Using simulation models, it is possible to repeatedly analyse the weaknesses of the machine design, to determine the effects of each machine component on its properties and to optimize them, but also to take account of ergonomic and other requirements.
