TECHNOLOGICAL METHODS TO FORM HIGH-QUALITY SURFACE OF PARTS MADE OF ALUMINUM AND COPPER ALLOYS

The surface quality of aluminum and copper alloy parts is studied when they are formed, which is important for transport engineering. The main task is to determine the conditions conducive to the formation of specified criteria for surface quality and to find out the dependencies of various factors when applying edge cutting machining and electrochemical processes. The research includes experimental and analytical parts, which are presented as conclusions, including the most optimal modes and conditions in terms of quality formation. The research methods are of an experimental and practical nature with the comparison and evaluation of the results obtained, in which the features of porous metal ceramics machining and methods for improving the efficiency of surface forming while maintaining the functional physical parameters of the part surfaces are considered. The novelty of the study is in finding dependencies of the obtained quality on the machining conditions and the comparative characteristics of the obtained surfaces not only in terms of changes in roughness, but also in surface porosity. As a result, recommendations are made for machining such materials, which minimize the effect of pore tightening and reduce deformation phenomena in the material.
