| Outline of Final Research Achievements |
In the micro deep drilling process, for example, whose diameter is less than 0.2mm or the length diameter ratio is over 20, both high productivity and high preciseness are strongly needed. We conducted to develop a low-frequency vibration (several hundred Hz) excitation method for worikpiece towards any optimal direction in order to minimize the tool breakage or to realize long tool life for the heat resistant alloy.
We developed a new fixing system which can hold the nozzle parts by 3-jaw chuck and apply controlled elliptical vibration generated by the spring system in arbitrary direction. In the verification results of the developed system, by the low-frequency vibration conditions of optimal 150 Hz to chip cutting, the elliptical vibration of the major axis 10μm and minor 3μm is accurately applied and it can achieve a fine deep-hole drilling on the nozzle shaped test piece.
