Composite materials are expected to be effective for use in mechanical and structural parts, such as airplane parts. Carbon Fiber Reinforced Plastics (CFRP) are frequently used. When CFRP are used for mechanical structural parts, the need to slice or drill them is inevitable ; an abrasive machining method by OD-blade has been widely used to slice them. However, one drawback of the OD-blade slicing method is low tool life due to the hardness of carbon fiber. This study was performed to establish and examine the practical applicability of the vibratory OD-blade slicing method to slice composite materials, such as CFRP. The obtained results are follows. (1) The slicing force and tool wear in vibratory slicing remarkably decreases compared with in the conventional slicing. (2) The slicing accuracy such as the surface roughness, waviness and edge chipping in the vibratory slicing method is similar to them in the conventional slicing method.

预计复合材料可有效用于机械和结构部件，例如飞机部件。碳纤维增强塑料（CFRP）是常用的材料。碳纤维复合材料用于机械结构件时，不可避免地需要对其进行切片或钻孔加工，采用OD刀片的研磨加工方法已被广泛应用。然而，OD-刀片切片方法的一个缺点是由于碳纤维的硬度导致的低工具寿命。本研究旨在建立和检查振动OD-刀片切片方法对复合材料（如CFRP）切片的实用性。所得结果如下。(1)与常规切削相比，振动切削的切削力和刀具磨损显著减小。(2)振动切片法的表面粗糙度、波纹度、崩边等切片精度与常规切片法相近。
