Abstract

Abstract: To overcome the problems in rough machining of casing parts such as multiple bosses, large machining allowance, low machinability of materials, fast tool wear and long process cycle, a tool-path planning method for the trochoidal milling of the aeroengine casing is proposed, with which the change of the tool load can be controlled effectively, the heating-cooling cycle is improved, the tool wear is retarded, and the machining efficiency can be increased in the rough machining process of casing. First of all, through an analysis of two trochoidal models, a mathematical model for the trochoidal milling is developed, and the advantages as well as the disadvantages of the trochoidal milling are discussed. Then, based on the characteristics of the casing parts, the model is discretized into a point model in the accuracy range. The model is unfolded by using the cone, and the mapping relationship between the unfolded model and the original one is established. According to the division and plane approximation of the machining area, the tool path of trochoidal rough machining for casing parts is generated. Finally, experiments on the trochoidal milling of tool wear, planar cavity and casing show that the trochoidal milling is effective in reducing the tool wear and prolonging the tool life. The validity and high efficiency of the proposed trajectory generation algorithm in the actual processing of the aeroengine casing are verified. The research achievements can effectively shorten the processing cycle, reduce the machining costs and improve the rough machining efficiency of casing parts.
