| Popis: | 1Conventional drilling of modern super alloys and composite material induces high stresses in the vicinity of drilled holes along with high thrust forces which lead to problems in terms of hole quality and accuracy as well as increased tool wear. A recent and promising technique to overcome these challenges is to introduce vibration assistance in the cutting zone by superimposing oscillating vibration in the feed direction of the tool. Two regimes of vibration excitation could be applied for this purpose: low frequency (100 μm) and high frequency ( ASME 2014 International Mechanical Engineering Congress and Exposition, IMECE 2014, 14 November 2014 through 20 November 2014 |
