本研究探討單點鑽石切削對不鏽鋼加工時不同刀具形狀對材料移除機制,刀具磨 耗,及加工後之表面性狀的影響。圓弧刀、圓椎刀及金字塔型刀三種不同刀具, 配合以不同的加工參數,來比較加工後的表面品質與刀具的磨耗情形。實驗結果 發現在適當的加工參數控制下,使用圓錐刀可以降低刀刃的磨耗得到鏡面的加工 表面,節省加工成本與加工的時間。 This study investigates the influence of tool geometries on the material removal mechanisms, tool wear and surface characteristics involved in and after machining stainless steel using single-point diamond turning technique. The surface finish and tool wear were compared after diamond-turning using different machining conditions with diamond tools of three different tool geometries (round-, cone- and pyramid-shaped). The experimental results show that under some adequately chosen machining conditions, it is possible to obtain a mirror-like surface finish with low tool wear as well as low machining cost and time using the cone-shaped diamond tool.
