As the core component of power machinery,the machining quality and efficiency of blade parts have been widely concerned by the industry,and the realization of efficient NC machining of blade parts is the research focus in this field.Tool selection is an important part to realize efficient NC milling of blade parts,which plays an important role in improving the quality and efficiency of blade processing and reducing cost.In this paper,the optimization technology of NC tool is studied for efficient NC milling of blade parts.The main research contents of this paper are as follows :1)Taking into account the structure,types and process characteristics of blade parts,the characteristics of tool requirements for NC milling of blade parts are analyzed.By analyzing the machining characteristics of blade parts,the shape,geometric size and structural characteristics of the tool are matched.Finally,the selection method of machining tools based on the machining characteristics of blade parts is summarized.2)The problem of tool structure optimization in blade NC milling is summarized,and a comprehensive evaluation system of multi-objective blade NC machining tool optimization with two-level structure is constructed.The processing time,cost and quality are taken as the optimization objectives of tool optimization.The CAM software simulation results of tool path trajectory,residual volume,cutting force and tool path trajectory time in machining are used as evaluation indexes.It is proposed to use gray correlation analysis and analytic hierarchy process to solve the comprehensive evaluation system of blade parts tool optimization.It lays a foundation for the optimization of cutting tools for efficient NC machining of blade parts.3)In the NC machining process of blade parts,the processing time and machining amount of blade body rough machining are large.UG NX and VERICUT software are used to compile and simulate the tool path of blade body rough machining tool,and the simulation evaluation index is processed.Finally,it is calculated that the insert milling cutter is the optimal tool for blade body rough machining.In order to solve the problem of cumbersome and complex data processing of evaluation index in the process of tool optimization,the GUI design tool of MATLAB software is used to design the human-computer interaction interface of gray correlation analysis and analytic hierarchy process.At the same time,the usability of the interface is verified,so as to provide a method for efficient NC machining tool optimization of blade parts.
