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.
