摘要
采用正交实验测量不同刃口钻头钻通孔PCB板材的轴向力,分析了钻通孔切削力的特性,研究了顶角2φ、螺旋角β、横刃厚W刀具结构对切削性能的影响,并通过正交实验对钻通孔钻头刃口参数进行优化。
Forces of drilling PCB are measured with different tools by orthogonal test. The effects of point angle 2φ,helix angle β,web W on cutting on the drilling are analyzed. As a result,a new type of drill is designed.
