铣刀是机械加工应用很广泛的一种刀具。在铣刀设计和使用中有时需要计算它的实际前角,即在铣削过程中真实起作用的前角,是在切屑排出平面(即切屑沿前倾面排出方向与铣削速度向量组成的平面)内测量的前角。目前
Milling cutter is a tool widely used in machining. It is sometimes necessary to calculate its actual rake angle during milling cutter design and use. That is, the actual rake angle during milling is at the chip discharge plane (ie, the plane along which the chips are discharged along the rake face and the milling speed vector) Inside the measurement of the angle. Currently
