使用镶硬质合金刀片的端铣刀进行铣削时,实践证明,切削用量的选择必须注意一个特殊情况:在一定范围内(铣切碳钢时,切削速度v<180米/分,走刀量S_z<0.07毫米/齿),提高切削速度v、走刀量S_z以及不使用冷却液,反而能提高端铣刀的耐用度,且使加工后的表面质量得到改善。一、加工情况与效果用直径D=200毫米、盘形镶YT 5刀齿的标准端铣力, The use of cemented carbide insert end mill for milling, the practice proved that the choice of cutting dosage must pay attention to a special case: within a certain range (milling carbon steel, the cutting speed v <180 m / min, the amount of walking S_z <0.07 mm / tooth), increasing the cutting speed v, the amount of cutting S_z, and the absence of coolant, on the contrary, increase the durability of the end mill and improve the quality of the machined surface. First, the processing conditions and effects With a diameter of D = 200 mm, disc-shaped inserts YT 5 standard tooth milling force,
