在電路板產業，「成形繪製」指的是工程師在將電路板設計圖送交至機 台切割前，利用 CAD 軟體在設計圖上描繪機台切割的路徑及修正。非常耗費時間及人力，重複性高且單調的工作且高度仰賴工程師多年經驗的累積以及對機台的了解。 使用傳統 CAD 軟體，要做到某些特定的功能還必須要使用其他多種功 能交互搭配才能完成，沒有聰明且自動的方式，每一筆描繪都必須由使用 者手動完成，導致整體編輯時間被大大拉長。 一般的最短路徑演算法並無法滿足解決此類問題的條件，在一個有大 量元件及複雜結構的設計圖中，預測使用者想要繪製的路徑是非常困難且 耗時的，演算法所提供的最短路徑往往不是使用者所想要的，若可以自動 計算路徑且融合使用者經驗，便能自動方便且準確的繪製路徑。 為了達成這個目的，本實驗室開發了一套針對成形繪製的 CAD 軟體— CoolPCB，融合了 CAD 軟體能夠處理大量物件且精準繪製的特性及 RPA 軟體所帶來自動化功能的優點，CoolPCB 引入了一套有別於傳統 CAD軟體的繪製方式，本論文將針對成形繪製提出創新的自動化路徑規劃方法，該方法結合路徑計算及使用者可控物件，以解決電路板生產廠商多年來的痛點。;To cut the PCB (Printed Circuit Board), engineers will use CAD (Computer Aided Design) software to design the path for CNC (Computer Numerical Control) machine and correct any error in the original design. This procedure is very time-consuming, repetitive and heavily depend on the experience of engineers. Using traditional CAD software is hard to complete the task in a smart and simple way since it requires user to combine many tools to perform specific functionality. User have to draw every path step by step and by themselves. Editing time is greatly grown and the company even need to hire more employee just to compensate the cost of time. Speaking of paths, a path finding algorithm may solve this situation. However, the shortest path that algorithm give is not applicable for every situation. If we can create a method that is flexible and automatic, it can be widely used and have a great success in PCB industry. In order to achieve this goal, our lab developed a tool that combine the advantage from normal CAD software which can handle massive amount of object in the file and RPA (Robotic Process Automation) software which provide automatic functionality to eliminate the repetition—CoolPCB. This paper also proposes a method with automatic path calculation and user-controllable object. It is fast, reliable and can solve the problem of PCB industry have for a long time.
