分析了槽铣AL 2014-T6时切削条件和刀具几何形状对表面粗糙度的影响。所考虑的参数是切削速度、进给量、切削深度、铣刀端部切削刃的后角和轴向后角。采用响应曲面法（RSM）和实验结果建立了干切削和冷却液条件下的表面粗糙度模型。结果表明，添加切削液可以降低干切粗糙度。影响干切削模型的显著因素是切削速度、进给量、后角和轴向后角;而影响冷却液模型的显著因素是进给量和后角。表面粗糙度一般随进给角、后角和轴向后角的增大而增大，当后角大于2.5°时。
The aim of this work was to analyze the influence of cutting condition and tool geometry on surface roughness when slot end milling AL2014-T6. The parameters considered were the cutting speed, feed, depth of cut, concavity and axial relief angles of the end cutting edge of the end mill. Surface roughness models for both dry cutting and coolant conditions were built using the response surface methodology (RSM) and the experimental results. The results showed that the dry-cut roughness was reduced by applying cutting fluid. The significant factors affecting the dry-cut model were the cutting speed, feed, concavity and axial relief angles; while for the coolant model, they were the feed and concavity angle. Surface roughness generally increases with the increase of feed, concavity and axial relief angles, while concavity angle is more than 2.5°.
