Abstract:

In order to realize micro Electrical Discharge Mchining (EDM) surface roughness evaluation, a fast Gauss evaluation algorithm of surface roughness is proposed based on the results of scanning electron microscopy (SEM). First, the Gauss evaluation algorithm is described in detail, and the data to be evaluated are preprocessed. Then, according to the SEM data of the micro electrical discharge machining, a fast evaluation algorithm is designed based on a Gauss Evaluation benchmark. Finally, with the input of the results obtained from micro electrical discharge machining and SEM on actual samples, the simulation experiments of surface roughness evaluation are carried out using the proposed fast Gauss evaluation method, convolution algorithm and FFT algorithm respectively. Experimental results show that, compared with the other algorithms, the proposed fast Gauss evaluation method significantly improves the efficiency of evaluation. Estimated time for 512×512 sampling points can be shortened to 2 s from 6 s and 4s of the other two conventional methods respectively.
