Then the error sources of the reaction type and electron type electric energy mete were analyzed and the theory analysis result through the concrete test have been proved. At last, the main conclusion has been drawn. When the induction type electric energy meter measures harmonics energy, the negative error characteristic appears. The higher the frequency of harmonics is, the greater the error is. The electron type electric energy meter can measure harmonics energy accurately in general cases. Except thermo-electrical conversion type electron type power meter, reaction type and electron type electric energy meter can measure direct current power.

The outstanding feature of the new cutting dynamometer contrary to other type of dynamometer sensor is that it is more similar to general lathe tool. It can be installed on knife rest, so it is same wit practice state of cutting. Sensitivity of dynamometer is more high, especially main cutting force can attain 7.4pC/N. The calibration results show that it has high static linearity, and its natural frequency is greater than 5 kilohertz, so the cutting dynamometer has fully reached the dynamometer standard stipulated by CIRP-STCC.Finally, in order to measure the cutting force, the orthogonal experiment method in which the three factors are the diameter of cutting, feed and spindle speed is performed.
