近年来，增强塑料（GFRP、CFRP等）广泛应用于制造业领域。随着对这种复合材料的需求的增加，对这些产品进行钻孔的需求迅速增加。本文研究了高速钢SKH 9和硬质合金KO1对玻璃钢和碳纤维复合材料的钻孔加工。PlO和超细晶粒）钻头。通过对刀具磨损形态、后刀面磨损宽度和切削力的研究，对四种钻头进行了比较。在碳纤维复合材料的钻削加工中，发现了一种新的刀具磨损形式，即“梳齿磨损”。另外，还发现，KO1的耐磨性最高，FG次之，高速钢钻头的磨损量明显大于硬质合金钻头。
In recent years, the reinforced plastics (GFRP, CFRP and others) are used in a wide field of manufacturing industry. With an increase of the demand for such composite materials, the need to drill these products is increasing rapidly. This paper deals with drilling of GFRP and CFRP, using high speed steel (SKH9) and cemented carbode (KOl. PlO and ultra-fine grain) drills. Comparison of four drills is done by investigating tool wear pattern, flank wear width and cutting forces. A new type of tool wear which should be referred to as "combing wear" was found in drilling of CFRP. In addition, it was found that KOl has the highest wear resistance, FG shows the second highest and the wear of high speed steel drill is remarkably larger than that of carbide drills.
