提高可转位球头立铣刀加工表面质量研究

Study on the Method for Improving the Surface Quality Machined by An Inserted Ball-nose End Mill

建立了可转位球头立铣刀周刃与端刀搭接方法的数学模型 ,利用该模型可计算出搭接处附近所加工出的表面的几何形状误差、周刃修型的控制参数 ,提出了减少加工误差的措施 ,并给出了计算实例。

A mathematical model for overlapping between the major cutting edge and the circumferential cutting edge of an inserted ball-nose end mill is developed,with which the profile errors of cutting surface,the controllable parameters for the circumferential cutting edge shape modification can be obtained.The measures for reducing the profile errors are proposed and the calculating example is also presented.
