Abstract
水刀由於具有冷切削、切削力小、適於自動化及具有高切削能力等優點，在國外工業界已廣被使用於切削非傳統難切材料, 如陶瓷、複合材料等等。自１９８０年代以降，水刀對各種不同材料切削性研究大量出現，不同切削操作形式（線切割、鑽孔、銑面、車圓）可行性紛被檢討的今日，吾人認為水刀綜合切削系統將是下一階段之研發重點。本研究建構了一個水刀ＣＮＣ圖型切削之原型系統。實作主要分三部份：建立水刀ＣＮＣ加工機硬體，對材料銑削性進行實驗分析，開發水刀之路徑規劃及評價程式。藉由原型系統的建立，吾人將可確實掌握水刀自動化之研究主題及方向。A prototype of abrasive waterjet (AWJ) machining system hasbeen established. There are three topics have been discussed:machining parameter selection, path generation and pathevalution. In consideration of the geometric result ofmachining, a series of experiments have been designed todetermine traverse rate, stand-off distance and lateral feedincrement. The experiments show that machine with three axes isnecessary for AWJ milling operation. Water-on-number, uncut-length, unstable-length, cross-number and NC- code-step aredefined to evaluate the machining path. With the above indexes,linear and cicling mode of path generation algorithm based onbitmap data are investigated.
