与传统划槽法相比,激光划槽有很多优点。
Comparing with the traditional slotting, the laser slotting has a lot of advantages.
由于激光对划槽材料几乎不产生机械冲力和压力,加上激光光斑小、划缝窄。
Because the laser process has no machine momentum and pressure, and has a small facula and a narrow slot material.
本课题对划槽宽度与扫描速度,电流,脉宽等关系做了深入的研究,总结出各个参数与宽度的经验关系式。
The paper also research on the relation between width and velocity, current, pulse width, and summarize the formulae between width and other parameters.
