摘要

通过引入工件倾角的定义，采用PCD 立铣刀对CFRP 层压板材料进行切边试验，并对加工过程中的铣削力进行测量，对加工表层不同缺陷形式进行观察分类。研究了不同表层纤维方向、工件倾角和刀具进给量对CFRP 表层的缺陷形式和演化规律。结果表明：CFRP 层压板铣削表层缺陷主要可以分为崩边、毛刺、撕裂和分层缺陷，其中表层撕裂缺陷是最主要的缺陷形式；刀具进给量是影响表层缺陷，尤其是撕裂缺陷形成和发展的最主要的因素；垂直于铺层平面的切削分力直接影响表层缺陷演变与转化。

Abstract

Polycrystalline diamond (PCD) end mill was applied during the trimming experiment of CFRP by introducing the definition of workpiece inclined angle. The milling forces were recoded and different types of machining defects were observed at the same time. The influences of carbon fiber angle

workpiece inclined angle and feed rate on the types and evolution of machining defects were analyzed. The results show that the main machining defect is avulsion of carbon fiber bundles with small amount of chipping

burrs and delamination. The feed rate of cutter is the most significant factor on the occurrence of machining defects especially on the avulsion of fiber bundles. The cutting force perpendicular to the laminate panel has the direct influence on the occurrence and evolution of defects.
