1、加工中心刀具切削參數(shù)CNC加工應(yīng)分為低速加工和高速加工兩大類，普通機(jī)是指機(jī)床轉(zhuǎn)數(shù)8000轉(zhuǎn)以內(nèi)的機(jī)床，高速機(jī)是指轉(zhuǎn)數(shù)能超過12000轉(zhuǎn)的機(jī)床，介于8000—12000之間的機(jī)床叫準(zhǔn)高速機(jī)，此參數(shù)只針對普通機(jī)。CNC加工工藝習(xí)慣上分三類，開粗，中光(半精)，光刀(精銑)，一般以為開粗宜用較大刀具(飛刀和端銑刀)并用較大的切削深度和步距(重切削)，以求快速大量的去除材料。光刀則以輕切削(小切深,，小步距)配合較高轉(zhuǎn)數(shù)和進(jìn)給運(yùn)行，以求得完美的表面精度。光平面用端銑刀(或圓角刀)和飛刀，光垂直壁用端銑刀，光曲面用球刀(或圓角刀)。在加工過程中，應(yīng)根據(jù)被加工零件的
2、材料硬度，選用適當(dāng)?shù)牡毒撸缢苣z，木料等可選用國產(chǎn)的白鋼刀。銅，鋁材以及硬度在洛氏38度以內(nèi)的鋼材(如45號鋼,王牌料)應(yīng)選用進(jìn)口的鋼刀及國產(chǎn)優(yōu)質(zhì)的鋼刀。硬度較大的材料(如淬硬模具鋼)應(yīng)優(yōu)先選用合金刀，鍍鈦刀或鎢鋼刀。本參數(shù)針對普通CNC機(jī)床，針對開粗和光刀分別對各種刀具加以說明(飛刀，白鋼，端銑刀，鎢鋼平銑刀，白鋼球刀，鎢鋼球刀)。因加工素材繁多，本表僅以富有代表性的鋁合金，45號鋼，不銹鋼加以說明。表一（飛刀開粗以45號鋼為例）刀具種類深度（毫米）步距F（進(jìn)給）S（轉(zhuǎn)速）￠40R6￠30R51128201200150015001700￠25R50.8
