The article considers the problems of manufacturing blades with high precision profile geometry. It analyzes existing processes of making precision blades and illustrates the blade basing systems that are used in the manufacturing process. Their advantages and disadvantages are marked.  The article offers the option to install the blade preform, the main advantage of which is simplicity of the base forms. The special attention is paid to the difficulties with control of the geometric parameters of blades airfoil. A represented technology under development excludes the use of mechanical methods for processing the blades airfoil. Based on this analysis, the author argues that the application of the proposed process to manufacture precision compressor blades ensures producing the items that meet the requirements of the drawing.
