Setting mode for precision systems of impact and laser engraving under conditions of uncertainty of characteristics
The Hertz impact interaction formula is extended to rigid bodies, the real physical characteristics of which a priori have a significant scatter and cannot be specified exactly. Fuzzy-functions are determined that characterize a micro-impact under conditions of indistinctly specified strength properties of the material of the processed halfspace and the geometry of the impact tool. It is shown that an effective solution of applied problems of precision engraving in conditions of this kind of uncertainty of parameters is the use of adaptive IT-technology based on the interactive pre-launch setting of the system. Keywords; impact engraving technology, micro impact, fuzzy parameters, critical parameters, fuzzy surfaces, gradation scale of shades.
