| Abstract: | Ultra-precision milling system is first presented in this paper. After that,it introduces the process of designing FIR low-pass digital filter by sptool toolbox in the MATLAB in detail,and analyzes the filtered result of the milling force curve. From the result,variety laws of frequency and amplitude parameters of the digital filter on filtered effect and design rules of the digital filter are presented. |
