摘　　要：小批量多品种的微波印制电路板(PCB)外形铣切加工,普遍采用“非叠版”方式进行,刀具局部区域切削刃的寿命到期,刀具就作报废处理。报废的刀具在其余的切削刃区域还存在着较大的利用空间。通过对常用微波印制电路板材料、酚醛树脂盖板材料铣切寿命的对比研究,提出了“深度递进铣切”的外形成型加工工艺。通过对刀具剩余切削刃的再利用,有效提升了刀具的整体使用寿命。该方法操作简便,与现有生产模式兼容良好,同时可降低铣刀消耗量30%~45%,经济效益显著。The shape milling of"small batches and varieties"microwave printed circuit boards(PCB)is generally carried out in a non-stacking mode.When the life of the cutting edge in the local area of the tool expires,the tool will be scrapped.These scrapped tools still have a large space for utilization in the remaining cutting recognition areas.In this paper,through the comparative study of the milling life of commonly used microwave circuit board materials and powdered aldehyde resin cover materials,the shape forming processing of"depth progressive milling"is proposed.Through the reuse of the remaining cutting edge life of the tools,the author effectively improves the overall service life of the tool.The method is easy to operate,well compatible with the existing production modes,and can reduce tool consumption by 30%to 45%,with significant economic benefits.
