Development of vibratory OD-blade slicing method with high efficiency and long tool life for composite materials

复合材料有望有效地用于机械和结构部件，如飞机部件。碳纤维增强塑料（CFRP）是常用的材料。当CFRP用于机械结构件时，不可避免地需要对其进行切片或钻孔；采用od刀的磨料加工方法对其进行切割已被广泛采用。然而，由于碳纤维的硬度，od刀片切片方法的一个缺点是刀具寿命低。本研究旨在建立并检验振动od叶片切片方法在CFRP等复合材料切片中的实际适用性。得到的结果如下：(1)与常规切削相比，振动切削的切削力和刀具磨损明显减小。(2)振动切片方法的表面粗糙度、波纹度、边缘切屑等切片精度与常规切片方法相似。

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.
