在切削加工中,切削液主要起冷却、润滑、清洗排屑以及防锈作用,还能提高加工效率和加工质量。但随着经济的发展,人们环保意识的增强,切削液的负面效应正逐步被重视。从经济环保等角度看,不使用切削液的干切削加工才是理想的绿色制造工艺方法。但干切削加工时摩擦力大,切削力大,切削温度高,完全的干切削对刀具的材料、结构、几何角度等工艺条件要求极为苛刻,使它的应用范围受到了很大限制。目前对刀具的冷却仍是最常用、最有效的方法。从刀具的磨损机理上分析,切削时产生的摩擦高温是造成刀具磨损的主要原因。切削液的主要作用也是通过液体气… 相似文献

In spite of their environmental and human health problems, the cutting fluids still have been used widely in industry due to cutting fluid application can increase cutting performance in metal cutting. In this article, the effect of the cutting fluid on surface roughness in boring of AISI 1030 low carbon steel was investigated depending on BUE and chip formations and other cutting parameters, such as cutting speed, feed rate and tool nose radius. In most of boring experiments, the wet cutting did not show more preferable results than dry cutting. However, cutting fluid application with big nose radius and small feed rate improved the surface roughness up to 80%. This progress was attributed to a favorable chip formation as much as effective cooling. 相似文献
