The maximal depth model for single-pass milling process, the depth and surface roughness for plane surface are established. The milled profile of a single-pass milling of the jet can be modeled as a cosine curve of the form. Therefore, the maximal depth model for single-pass milling is established which indicates the quantitative relationship between the AWJ single-pass milling depth and the milling parameters.
