The reasons for the divergence between the calculated results of the height of the microasperities of the kinematic and geometric representations of the formation of the surface with the edge tool and their values obtained during machining are studied. The analysis of the formation of microasperities in the area of chip formation is made, and the mechanism of increment of their height is considered, due to the fact that not all of the processed material allowance is removed during cutting. Most of the material is removed in the form of chips, and a smaller part of  it flows around the back surface of the tool and pressed out into the top of the asperity. The promissing directions of  microasperities height control on the treated surface are determined, and it is proposed to develop and apply tools that reduce the value of the end cutting edge angle and increase the radius at the top, as well as tools that minimize plastic deformation of the treated material in front of the front surface. The complex of studies on the processing of  parts from materials with heterogeneous structure showed that the features of the structure limit the possibility of  technological quality control of the treated surface of products.
