Milling and Milling Cutter

铣削和铣刀

Milling is a machining process that is carried out by means of a multiedge rotating tool known asa milling cutter.

铣削是采用被称为铣刀的多刃旋转刀具完成的机加工作业。

In this proces*etal removal is achieved through combining the rotary motion of the millingcutter and linear moti* of the workpiece simultaneously. Milling operati* are employed inproducing flat, co*ured and helical surfaces as well as for thread- and gear-cuttingoperation.

在此工艺中金属去除是通过铣刀的旋转运动和工件的直线运动的组合实现的。铣削作业既可用于生成平面、轮廓面和螺旋面也可用于切削螺纹和齿轮。

Each of the cutting edges of a milling cutter acts as an individual single-point cutter when itengages with the workpiece metal. Therefore, each of those cutting edges has appropriaterake and relief angles.

在铣刀切削工件金属时铣刀的每条切削刃都象一单独的单刃刀具一样作用。所以每条切削刃都适当的前后角。
