Figure 3
Fourier-transform power spectra of the JX130 (left Y axis) and the ROD800 (right Y axis) errors shown in Fig. 2. The sharp peaks in the spectrum of the JX130 located at 22.7592, 45.5239, 68.2887 and 91.0534 deg−1 correspond to the systematic characteristic error of the JX130. The sharp peaks in both spectra located at 20.0, 10.0 and 5.0 deg−1, and other integer positions correspond to the characteristic error of the rotary table. |
