镶硬质合金端铣刀的崩刃与龟裂的研究

Study on the Chipping and Cracking of End mill of Inserting Sintered Carbide

为了解决转位式端铣刀在铣削过程的崩刃问题,提出了银白屑切削法的刃口和最佳刃带宽度,使切削力减小18％～38％,功耗减小28％左右,刀具耐用度提高2倍以上,节约生产成本15％以上。并分析了4种切削的位置和直径大小的效果;给出推荐铣削用量,便于生产中应用。

To solve the breaking problem in milling process of throw-away insert milling cutter, this paper puts forward the cutting edge and promise edge width, de which decrease the cutting force by 18%-38%, power consumption by 28%, save production cost by 15% and enhance the tool life above two times. The paper also analyses the effect of four kinds of cutting position and diameter size and gives a reference cutting quantity for production application
