基于卷屑的球头立铣刀前刀面造型

Rake Face Construction for Ball-nose End Mills Based on Chip Curling

采用微分几何中的曲率分析方法对球头立铣刀前刀面上端刃法线方向和切屑流出方向的法曲率进行了详细的分析计算 ,并给出了切屑流经前刀面时卷曲半径的计算方法。

The rake face normal curvatures of a ball nose end mill in normal direction and chip flow direction are analyzed and calculated in detail in this paper.As a result,an approach for computing the radius of chip curling when the chip flows along the rake face is obtained.
