Polzunov Altai State Technical University, 46 Lenina avenue, Barnaul, Altai region, 656038, Russian Federation Abstract Modern CNC equipment allows us to obtain a variety of complicated profile surface. Processing of complex profile surfaces is carried out by mills of different design. However, the creation of control programs for machining on the CNC machine is a time consuming process. The availability of modern CAD/CAM systems greatly facilitate the process of designing the part and the technology of its processing. The sequence of milling operations depends on the number of surfaces, the individual zones to be processed during this operation, the surface roughness requirements, and the machining accuracy. The choice of cutting tools for each operation is important and affects the processing performance. The paper presents a technique for designing milling operations for processing complex profile surfaces of a part. The initial data for the purpose of milling operations - the type of processing, cutting tool and cutting modes are: processed material; detail configuration; surface roughness; the accuracy on the treated surface; the range of radius of the surfaces. The type of treatment is assigned from the precision and roughness of the processed complex profile surface. Then, for all assigned treatments select the desired radius cutter from the cutting tool database. The choice of mill depends on the configuration details. In addition, recommendations are given for cutting parameters. Keywords Machining of complex profile surfaces, the method of designing the operations, the design of CAM systems.
