An impact of a machining method upon life of engineering parts made of dispersion-strengthened polymeric composites is analyzed. Comparative tests for cyclic strength of samples obtained in a common way of milling with a diamond tool and with the use of hydro-jet cutting (HJC) were carried out. The tests were based upon the assessment of the cycle amount before decomposition and an amplitude-frequency characteristic drift of a sample at vibration impact at its resonance frequency. The HJC outlook as an alternative of common machining methods of dispersion-strengthened polymeric composites (DSPC) is confirmed.
