油膜附水滴润滑技术下进给量和进给速度对车削不锈钢的影响

摘要

使用油膜附水滴切削液(oil-on-water,OoW)对不锈钢进行连续切削试验.研究不同进给量和进给速度下,工件表面粗糙度和刀具寿命变化规律.对试验数据进行回归分析,建立有关刀具寿命和工件表面粗糙度的经验公式.根据所得到的经验公式针对刀具寿命进行优化.试验结果表明,刀具寿命随着进给量和进给速度的增大而减小,表面粗糙度随着进给量的增大而增大,随着进给速度的增大而减小.%Oil-on-water cutting fluid was used to turning hardened stainless steel continuously .Tool life and surface toughness are investigated under various feed and cutting speed .Regression analysis is used to develop em-pirical model for tool life and surface roughness .Tool life is optimized according to the equation .The experiment shows that tool life is inversely proportional to feed and cutting speed , surface roughness is inversely proportional to feed whereas proportional to cutting speed .
