文摘

3D finite element simulation of ultrasonically-assisted drilling is represented. Influence of harmonic movement of drill bit on built-up edge formation is evaluated. Analysis of heat generation affected by ultrasonic vibrations is carried out. Forces are smaller in ultrasonic assisted drilling compared to the conventional one. Modification of continuous chip to segmented chip in UAD is happened by increase of deformed chip curling.
