The geometry of non-circular surfaces allows for multiple profiling schemes. This allows to choose rational one when designing of machine tools and equipment depending on the shape surface and conditions of production. Based on the theory of surfaces formed a method of analysis of non-circular surfaces grading schemes. This allows to carry out a systematic analysis of the methods of profiling non-circular surfaces and develop innovative ways of processing. The essential features of the profiling schemes were established which are important for comparison and implementation on machine tools. These features are shape-producing elements, the result of their interaction with the nominal surface of the product, the type of formation (full, partial), and others. The structure of the executive movements for profiling schemes was examined. Circuit forming non-circular surfaces with the combined movements of the profiling and cutting are preferred. This allows to proceed with non-circular surfaces on universal machine tools with simple kinematics. Rational schemes of profiling non- circular surfaces in the processing of various disk and cylindrical cutters, cutter heads, round and non-round cutters are presented as a result of research.
