摘要

CAM系統中，五軸工件輪廓曲面是高階多項式（自由曲面）構成，通常使用多直線短單節來逼近曲線，CAM所產生的不良加工路徑可能誘發機台共振，導致工件呈現不規則表面。本文針對國外三大商用控制器廠商（FANUC、SIEMENS、HEIDENHIAN）所推出的五軸控制器中的高階功能進行介紹，並將本次技術著重在控制器的轉角平滑化功能上，透過擬合平滑刀具路徑來改善不良的加工路徑。藉由與各位業界先進分享工研院對此功能的學理與應用之研究，期望可提供國內五軸加工使用者，對於控制器使用之相關資訊。

In the CAM system, the five-axis workpiece contour surface is composed of high-order polynomials (free-form surfaces). Usually, a multi-line short block is used to approximate the curve. The poor machining path generated by the CAM may induce machine resonance, resulting in the workpiece exhibiting an irregular surface. In this study, the high-level functions of the five-axis controllers introduced by three foreign commercial controller manufacturers (FANUC, SIEMENS, HEIDENHIAN) are explored. The technology development is focused on the corner smoothing function of the controller, and improvment of the poor machining path by fitting and smoothing the tool path. By sharing with the industry, the Industrial Technology Research Institute has studied the theory and application of this function aiming to be capable of providing relevant information for domestic users who are engaged in five-axis machining.
