摘要

複雜或具多曲面的元件其在兩曲面交接處的倒圓角面切削(清角加工)經常是具有挑戰性的，例如葉輪葉片面與輪毂面間的倒圓角加工，通常必須以五軸加工來規劃。本文針對清角加工提出一套刀具路徑規劃法，建構單道次或多道次清角加工刀具路徑，並考量容許的扇形餘料高來設定清角的道次。本文方法透過相交曲面參數方程式資料，實例分析計算規劃出清角刀具路徑，並經CAD/CAM軟體模擬及在機台實際切削結果顯示，本文清角刀具路徑規劃法確實可行。

The blending surface machining or so called pencil-cut machining between two curved surfaces is not easy, especially for complex or multi-surface components such as the blending surface of the impeller blade surface and hub surface. Usually, they must be cutting by using five-axis machine tool. In this paper, we proposed a tool path planning method for the blending surface pencil-cut machining. With this method, the pencil-cut (clean-up) machining tool path and the clean-up stages required can be generated by considering the allowable residual scallop material of the machined blending surface. For verification, the proposed method the parametric equations information of the intersecting curved surfaces to plan and calculate the tool paths for blending surface clean-up machining. By means of CAD/CAM software simulations and the actual machining experiments, the results show the present clean-up tool path planning method is actually feasible.
