本研究旨在发展可行的碳纤维增强复合材料（CFRP）加工技术。对碳纤维复合材料的加工进行了基础研究，其中加工参数，即切削速度，进给量和切削深度，是不同的。三种类型的切削刀具刀片，即，未涂覆的碳化钨，陶瓷和立方氮化硼（CBN），被用来加工两种类型的标本，短（不连续）和长（连续）纤维碳环氧复合材料。对于短碳纤维复合材料，实验数据表明，刀具磨损，表面光洁度和切削力波动相对于切削深度，进给速度和切削速度。然而，对于长纤维碳复合材料，对于固定的材料去除率，当CFRP复合材料在较低的切削速度下加工时，刀具磨损最小。此外，CBN刀片显示出上级刀具磨损性能和更好的表面光洁度相比，碳化钨和陶瓷刀片。
This research aims to develop feasible techniques for machining Carbon Fiber Reinforced Composites (CFRP). Fundamental studies on the machining of CFRP were carried out, where the machining parameters namely cutting speed, feed rate and depth of cut, were varied. Three types of cutting tool inserts namely, uncoated tungsten carbides, ceramic and cubic boron nitride (CBN), were used to machine two types of specimens, short (discontinuous) and long (continuous) fiber carbon epoxy composites. For short carbon fiber composites, experimental data shows that the tool wear, the surface finish and the cutting force fluctuate with respect to the depth of cut, the feed rate and the cutting speed. However, for long fiber carbon composites, for a fixed material removal rate, the tool wear was minimum when the CFRP composites were machined at lower cutting speeds. In addition, CBN inserts showed superior tool wear properties and better surface finish as compared to tungsten carbide and ceramic inserts.
