摘　　要：L型相交槽毛刺是印制电路板制程中最常见的一个不良现象,也是机械钻孔加工中的一个技术难点。实验结果表明:钻槽路径由原来的顺时针方向优化为逆时针方向,再使用除毛刺刀具切除相交内角,从而达到改善毛刺效果。The burr of L-shaped intersecting groove is the most common bad phenomenon in the process of printed circuit board,and it is also a technical difficulty in the machining of mechanical drilling.The experimental results show that the drilling path is optimized from the original clockwise direction to the counterclockwise direction,and then the burr cutting tool is used to cut off the intersecting inner corners,thus achieves the effect of improving burrs.
