Research on the High Efficiency Modular Programming for Typical Features of Shell Body

As the core component of aerospace products, the shell body has the characteristics of complex structure, high dimensional precision, large material removal rate, complicated process and long processing cycle. In the process of shell NC machining, there are many problems such as difficult programming, heavy repetitive work, low efficiency, and the programming quality which is closely related to the ability level of programmers. In order to meet the requirements of high efficiency and reliability, relying on mature commercial CAM software, through the analysis of typical features of shell body, the typical feature automatic programming module is developed which is based on the UG NX software platform. The module effectively improves the quality stability of the processing program, and greatly reduces the amount of programming operations of technicians, and improves the efficiency of the process design.
