Abstract

Ultra-precision raster milling (UPRM) is an advanced manufacturing process for machining non-rotational symmetric freeform surfaces with nanometric surface roughness without the need for any subsequent polishing. Due to different cutting mechanics, the UPRM process is very dependent on cutting strategies (up-cutting and down-cutting) as compared with ultra-precision diamond turning and conventional milling. In this paper, the power spectral density (PSD) are used to analyze the characteristics of the cutting forces with different cutting depths. The effect of the high frequencies changes, and the contribution rate is gradually reducing with the increment of depth of cut, which means that the cutting chips will become softer based on the temperature increment from cutting forces, due to soft phase absorbs one part of imposed strain.
