Abstract
In the 1st report, the dynamic influence of the dynamometer upon the grinding depth of cut and the fidelity of measurement considering it were analyzed, and from these analyses some fundamental formulae were introduced and enabled the design of the dynamometer with the specified allowable error and frequency range for the measurement. Furthermore, design procedures considering practical technical problems were set up.In the present paper, following these design procedures, the octahedral elastic ring dynamometer with the specifications of the allowable error 20% and the frequency ranges 01700 Hz (normal direction) and 01100 Hz (horizontal direction), and the two-force component piezoelectric dynamometer with the natural frequency as high as 180 kHz and the static rigidity more than 100 kg/μ have been experimentally produced. The former is an example in such a case where measuring frequencies are low and the additional damper can be easily equipped. The latter is an example in such a case where the natural frequency of the dynamometer is high and it is technically difficult to attach the damper.And expected results are obtained.
