Abstract

In this paper, authors take attempt to adapt the two-dimensional wavelet transform to assess the value of the minimum chip thickness for the face milling process of C45 steel. The images of surface layer from selected measuring devices were analyzed using a mother wavelet bior6.8. The analysis based on the wavelet transform revealed in signals three characteristics zones of the impact of cutting insert on the workpiece during initiation of the cutting process. The obtained values allowed to determine the relative method accuracy and to evaluate the possibility of application the particular measuring machines to assess the value of hmin parameter.
