一、前言玻璃纤维强化塑料(GFRP)和碳纤维强化塑料(CFRP)已在各工业部门得到广泛应用,其需要量正在日益增长。作者用高速钢钻头和三种硬质合金钻头,对GFRP和CFRP进行钻削加工,研究钻头的磨损形态和磨损进展状态,将各种刀具材料加以比较,并探讨钻头的磨损机理。二、实验装置和实验方法实验使用机床为MH—20型高速立式铣床。刀具材料:高速钢钻头采用SKH9;硬质合金钻头采用K01、P10和FG三种。试验钻头的各种参数如表1所示。图1为硬质合金钻
I. Introduction Glass fiber reinforced plastic (GFRP) and carbon fiber reinforced plastic (CFRP) have been widely used in various industrial sectors and their requirements are growing. The authors used high-speed steel drill bits and three carbide drill bits to drill GFRP and CFRP. The wear status and wear status of the drill bits were studied. Various tool materials were compared and the wear mechanism of the drill bits was discussed. Second, the experimental setup and experimental methods Experimental machine using MH-20 high-speed vertical milling machine. Tool material: high-speed steel drill bit with SKH9; carbide drill with K01, P10 and FG three. Table 1 shows the various parameters of the test bit. Figure 1 for the carbide drill
