STS 316L 스테인리스강의 미세 드릴가공 특성에 관한 연구

In this research, to the effort reaching the needed processing shape and preciseness, I suggest cutting feature data about STS 316L stainless steel, when you perform micro-drilling with machining center, using solid tungsten carbide drill(∅0.15). There are the cutting conditions, which I found the changes of Thrust and Torque in accordance with, to restrain the built-up edge occurrence when you process micro drilling, to maintain the shape of optimize chip, and to get a fine surface roughness inside of drill hole. I also try applying them in a real spinneret processing to see possibilities to make them better.
