摘　　要：研究的某火箭燃烧室壳体的结构复杂,精度要求高,由于其加工特征较多,数控程序复杂,无法人为判断程序的正确性,在加工中易出现碰撞、干涉和过(欠)切等问题,加工质量不易保证。针对该问题,基于VERICUT对壳体进行数控仿真加工,模拟实际加工过程。首先,根据壳体的结构特征制定加工方案,针对其复杂的型面特征采用四轴加工中心,并在UG中建立了加工中心的三维模型;其次,根据实际机床运动关系在VERICUT中搭建了四轴虚拟加工中心,配置相应参数,完成机床仿真系统建立;最后,对壳体进行仿真加工,验证了数控程序的正确性,并将验证的程序用于实际加工,加工结果充分验证了建立的四轴虚拟加工中心的正确性和有效性。The shell of the rocket combustion chamber is complicated in structure and high in precision requirements.It is impossible to judge the correctness of the program manually for its many machining features and complex NC program.Problems such as collision,interference and over/under cutting are easy to occur during machining,and the processing quality is not easy to guarantee.Aiming at the problem,the NC simulation machining of the shell is carried out based on VERICUT to simulate the actual machining process.Firstly,according to the structure characteristics of the shell,a four-axis machining center is adopted to solve the complex profile characteristics,and the 3D model of the machining center is established in UG.Secondly,a four-axis virtual machining center is established in VERICUT according to the actual machine tool motion relationship,and corresponding parameters are configured to complete the establishment of the simulation machining system.Finally,the machining of the shell is simulated to verify the correctness of the NC program.The verified program is applied to the actual machining,and the machining results fully verify the correctness and effectiveness of the four-axis virtual machining center established in this study.
