ELLIPTIC VIBRATION CUTTING PROCESSING METHOD

PROBLEM TO BE SOLVED: To provide a processing method for cutting a ferrous material into a mirror surface with elliptic vibration cutting processing, especially ultrasonic elliptic vibration cutting processing.SOLUTION: An elliptic vibration cutting processing method for processing a flat surface or free-form surface on a cutting object material 11 by elliptically vibrating a tip 14 of a cutting tool 10 relatively to the cutting object material 11 performs the elliptic vibration cutting processing by making the cutting direction of the cutting tool 10 and the rolling direction of the cutting object material 11 substantially vertical to each other. As the cutting tool 10, any cutting tool among a single crystal diamond coated tool, a nano-polycrystalline diamond coated tool and a polycrystalline diamond coated tool can be used.SELECTED DRAWING: Figure 5 【課題】楕円振動切削加工、特に超音波楕円振動切削加工により鉄鋼材料を鏡面に切削加工する加工方法を提供することを課題とする。【解決手段】本発明の楕円振動切削加工方法は、切削工具１０の刃先１４を被削材１１に対して相対的に楕円振動させながら被削材１１に平面又は自由曲面を加工する楕円振動切削加工方法であって、切削工具１０の切削方向と被削材１１の圧延方向とを略垂直にして楕円振動切削加工を行う。また、切削工具１０は、単結晶ダイヤモンド被覆工具、ナノ多結晶ダイヤモンド被覆工具、多結晶ダイヤモンド被覆工具のうちのいずれかの切削工具を用いることができる。【選択図】図５
