In the machining of fiber reinforced composite materials with cuttin tool, smooth surface without subsurface cracks can be obtained only under limited combination of cutting conditions. In this study, the mechanism of surface generation in the machining was observed, and, based on this observation, the conditions to get good surface were found. A relatively simple method for the measurement of cutting edge sharpness was developed and used in this study.The importance of the sharpness to get good surface was indicated quantitatively by using this method.Main results obtained are as follows: (1) Three types of surface generation exist in the machinig of GFRP. Good quality of surface is obtained when fibers are cut at the contact with the cutting edge of tool. (2) Good surface can be obtained by (a) decreasing the undercformed chip thickness , (b) increasing the rake angle and inclination angle of cutting tool, and (c) sharpening the cutting edge of tool. (3) Peripheral milling is preferable to get good surface. (4) In the machining of FRM with short fibers of whisker, fibers could not be cutoff.

在纤维增强复合材料的切削加工中，只有在有限的切削条件组合下才能获得无亚表面裂纹的光滑表面。本文对切削加工中的表面生成机理进行了观察，并在此基础上找到了获得良好表面的条件。本文提出了一种比较简单的测量切削刃锋利度的方法，并将其应用于本研究中。用这种方法定量地表明了锋利度对获得良好表面的重要性。主要结果如下：（1）玻璃钢加工中存在三种表面生成方式。当纤维在与刀具的切削刃接触处被切削时，获得了良好的表面质量。(2)通过减小欠形切屑厚度、增大刀具前角和倾角、刃磨刀具刃口等措施，可以获得良好的表面质量。(3)为了获得良好的表面，优选周边铣削。(4)在晶须短纤维的FRM加工中，纤维不能切断。
