摘要
整体叶轮型面的复杂性,导致造型和数控编程都有一定的难度。基于UG和VC++开发平台,采用等残留高度法,结合全局干涉和局部干涉刀位的修正原理,编制了无干涉刀位轨迹算法。开发出干涉较严重的微型叶轮类零件的五坐标加工程序。通过实验证明,无干涉刀位轨迹算法是可行的,提高了UG生成整体叶轮刀路的效率,减少了操作,从而提高编程效率,同时可以有效地减少冗余刀具轨迹,提高加工效率和表面质量。
The complex surface of the integral impeller leads to the difficuhies of modeling and NC programming. Based on UG and VC ＋＋ development platform, adopting the iso-scallop method, with the correcting principle in the global and local interference,developed the five-axis processing program with non-interference in micro-impeller. Experiments show that tool-path algorithm with non-interference is feasible to raise the UG generation efficiency of the integral impeller＇s tool-path and to reduce the operation, thereby enhancing the efficiency of the program, meanwhile effectively reduces redundant too-path, improves processing efficiency and quality of the surface.
