摘要
本文针对金刚石砂轮磨削印刷线路板(PCB)铣刀过程中铣刀切削刃产生的锯齿现象进行了分析,研究了砂轮粒度、砂轮转速以及切沟速度对铣刀切削刃锯齿的影响。研究结果表明,随着砂轮粒度的减小,切削刃质量得到提高,砂轮转速和切沟速度对切削刃质量都有影响,其中砂轮粒度对切削刃质量的影响最为重要。
The edge aliasing phenomenon on the cutter used for printed circuit board（PCB） milling often occur during the grinding with diamond wheel.In this paper,the effects of wheel diamond grit size,wheel speed and feed rate on the edge aliasing were studied.The results showed that the quality of cutting edge of milling cutter was improved with the decrease of wheel diamond grit size.The wheel speed and feed rate also had influence on the quality of the cutting edge.The wheel diamond grit size was the most important influencing factor on the cutting edge.
