... to the drill body. The response measurements are conducted in a noncontact manner using a laser Doppler vibrometer system. In addition, to perform the comparison on a complete frequency response function, rather than on only natural frequencies and mode shapes, an impact hammer test with a miniature hammer...

..., a bandwidth criterion based on cutting parameters is defined in order to permit clear observation of the mean oscillation of the cutting force. The frequency response of a dynamometer is then analyzed over a wide frequency range. A 2 kHz bandwidth can be defined for an efficient correction of cutting force...

... to mathematically couple the spindle/micromachine and arbitrary microtools with different geometries. The frequency response functions (FRFs) of the spindle/micromachine tool are measured experimentally through impact hammer testing, utilizing laser displacement and capacitance sensors. The dynamics of an arbitrary...

... at t = t * = 0.003   s , drilling depth ξ t = 0 + . This time is that of the microdrill going into the workpiece. After the drill is in the workpiece, the amplitude response of the drill becomes depressed. Figure 6 ( b ) shows the dynamic frequency response...

... of the tool point dynamic response by combining frequency response measurements of individual components through appropriate connections. Experimental verification of the receptance coupling method for various tool geometries (e.g., diameter and length) and holders (HSK 63A collet and shrink fit) is given...

... of the torsional-axial coupling is opposite that of traditional cutting in that an increase in cutting forces leads to axial extension and greater chip load. Because of this sign difference, the limiting depth of cut is governed by the positive real part of the frequency response function, which explains...
