| 摘 要： | 自由曲面用平头立铣刀五坐标数控加工可以明显地提高切削效率和零件表面质量，但无干涉刀位产生一直是个难以解决的问题，本文对其中的几个关键问题进行了研究，导出了平头立铣刀的有效切削半径的一种计算方法，给出了自适应走刀步长度算法和切削行距的计算公式，最后给出了无干涉刀位生成方法，并用实例验证了方法的可行性，为提高加工效率和精度提供了有效途径。

| Abstract: | The 5-axis machining of free curved surfaces with a flat end cutter can improve the material-removal rate and the surface quality,at the same time,the generation of gouge free cutter location is more complex.In the paper,several key problems are researched.The effective radius of a flat end cutter is defined.Methods of defining the step lengths and step intervals are presented.In the end,the producing of gouge free cutter location is put forward,the reliability of methods is verified by example.This provided an effective way for improving the machining efficiency and accuracy. |
