中文摘要 切削工序編排相關研究已發展多年,當中又以單一加工工序討論聲量較高,許多學者提出優良的研究結果,大致已有標準作業模式。而在完整的刀具路徑規劃中,普遍於精加工前會施加一工序去除零件表層多餘材料,藉此穩定精加工刀具負荷提升零件表面品質,但較少文獻以此加工道次之工序編排及餘量設定為主題進行討論,使路徑規劃方法選擇上仍有許多討論空間,可能會因為切削刀具選用、加工方法選擇或餘量設定不當,進而使生產效率大幅降低及加工失敗等狀況層出不窮。為改善當前仰賴人力的加工規劃作業方式,本研究以德國西門子公司提供之應用程式介面(Application Programming Interface,API)於NX電腦輔助製造軟體上進行自動刀具路徑規劃系統開發,並以2.5D工件之最佳切削方法組合選用與餘量設定為主要的研究主題,系統內整合了零件幾何辨識、切削刀具選用與加工工法選擇等多種功能,另以實際切削實驗取得多把刀具加工後產生的次表面破壞為依據,建立餘量設定演算區間,並使用動態規劃(Dynamic Programming,DP)與窮舉演算方法(Exhaustive Search)構築系統演算核心,逐一計算多種可能的切削方法組合與餘量設定之加工效能,從中挑選出最佳的加工規劃模式,藉此實現自動刀具路徑規劃及最佳化的目標,提供工程師加工路徑規劃樣板,減少人為疏失發生機率,提升產線整體生產效能。
英文摘要 This research developeds an automatic tool path planning system. The system integrates various functions such as geometry recognition, cutting tool selection, and milling strategies setting etc. Actual experiments were performed to obtain the sub-surface damage after milling for establishing standard allowance setting analysis method. The dynamic programming and exhaustive search were utilized to build the system’s calculation framework. The algorithm evaluates different machining methods and allowance setting to select the most efficient result to achieve the optimal automatic tool path planning. The method proposed in this research is implemented on the computer-aided manufacturing software NX. The method provides engineers with a standard tool path planning, reducing the occurrence of machining failures and improving the productivity.
