标题：Investigation of vibration assisted drilling prospects for improving machining characteristics of hard to machine materials at high and low frequency ranges
摘要：The article investigates applicability of vibration assistance based methods for improvement of machining capabilities of hard to machine materials at low and high frequency ranges. The literature overview of hard to machine materials was performed and two distinct cases were distinguished – machining of hard, brittle materials and machining of human bone tissue. Experimental studies of vibration assisted drilling application for the two cases at high and low frequency ranges were conducted. Experimental results showed improvements of selected criteria in both cases of vibration assisted drilling.
