研磨端銑刀精度補正系統開發

近年來，切削加工技術在高速銑削、硬材切削、微細形狀切削等領域有快速發展，而隨著新型工程材料的開發應用以及零件的小型化與精密化，使用者對於刀具產品的需求以及具有高附加價值與高生產效率刀具的日趨增長，故刀具製造商正積極開發適用於各種加工用途的高效能刀具並在國內外紛紛擴大其產能。本論文是以五軸工具磨床建構出研磨端銑刀精度補正系統，刀具研磨時砂輪會產生磨耗，因而造成研磨刀具尺寸與幾何精度產生誤差，因此在研磨過程中需適當的調整研磨參數與補正砂輪參數，將刀具影像量測結果做為輸入值並經過一系列詳細數學模組的推導以及縝密的研磨製程分析，可輸出刀具研磨時因砂輪磨耗所造成研磨點的偏移值，此為提昇刀具研磨時的刀具尺寸與幾何角度精度的關鍵性技術。由實驗結果顯示，本研究所開發的系統能夠在最少的時間與成本條件下，達到刀具研磨的精度，提升刀具的生產效率，降低生產成本並提升刀具研磨品質與技術，並達到標準化的研磨端銑刀製程。

In recent years, the machining technology in high speed milling and cutting for hard materials or fine shapes develops fast. Due to the development of new engineering materials and components miniaturization and precision, there is a great demand for high value-added and high productivity cutting tools. Therefore, manufacturers are actively developing high-performance cutting tools for a variety of processing applications and expand their production capacity. This thesis establishes a precision compensation system for grinding end mills based on a five-axis tool grinder. Owing to the wear of grinding wheels, this leads to the geometric error of cutting tools. Thus, it needs to adjust the grinding parameters to compensate the parameters of grinding wheels. We measured the tool images as input values, and derived mathematical modules and analyzed the grinding processes. Then the offset of grinding point can be obtained for the wear of grinding wheel. The experimental results show that the developed system in this study can improve the geometric accuracy, quality, production efficiency of cutting tools and reduce production costs. Furthermore, it also can achieve the standard processes for grinding end mills.
