刀具研磨進退刀製程規劃

Approach Retraction Process Planning for Tool Grinding

高速銑削所使用的端銑刀價格相當昂貴，為降低端銑刀的生產成本，刀具製造廠大多以提昇刀具的產能因應。本研究結合CAD/CAM端銑刀研磨製造系統軟體及VERICUT切削模擬軟體，探討端銑刀研磨進退刀製程。文中著重在退刀量及提刀距離的演算，再配合進退刀順序通則，以改善端銑刀研磨進退刀製程。研究結果顯示，以本文所提出的端銑刀研磨進退刀順序通則能夠確實有效縮短端銑刀研磨時間，增進研磨效率。

The end mills used for high-speed milling processes are very expensive. Hence, most tool manufacturers strive to cut down on production cost by enhancing the corresponding production capacity. For this purpose, this study uses CAD/CAM software for a manufacturing system to grind end mills coupled with the VERICUT simulation software for cutting to investigate the approach and retraction processes for grinding end mills. Calculation of retraction value and retraction distance is the major task here. Furthermore, the general sequence of approach and retraction is further investigated for improvement. The results show that the optimal general sequence obtained in this study can effectively shorten the grinding time and also improve grinding efficiency.
