摘要

因應全球加工機市場講求高效率的生產加工、降低品質瑕疵、提升產品品質等需求，各大智能化加工業者如DMG MORI、MAZAK、FANUC 等已紛紛投入工業4.0智能化加工機的軟體技術與控制器開發，因此，本文將針對RAMI4.0架構之閉迴路誤差補償技術作開發，有效解決精密加工工件誤差造成之來源並將其修正，來因應傳統加工業者所面臨之經驗斷層與效率問題。透過工件誤差量測，搭配齊次轉換矩陣與治具、工件座標之關鍵尺寸與作動方式建立誤差轉換矩陣，使用非線性回歸逆推演算法判斷誤差值範圍，並將其結果直接修正於治具，供加工者迅速修正誤差。

In order to keep pace with the fourth industrial revolution, leading global manufacturers such as DMG MORI, MAZAK and FANUC have been involved in the development of controller and software to improve machine intelligence in order to achieve high-efficiency production, shorten time-to-market, and improve product quality. This paper discusses development of error compensation technique based on the closed loop of RAMI4.0 architecture. An algorithm of the stream of variation analysis (SOVA) is proposed to achieve robust design by identifying sources of error and hence remove the errors. The design focuses on the knowledge-based machining.
