加工中心刀具切削參數(shù)CNC加工應分為低速加工和高速加工兩大類，普通機是指機床轉(zhuǎn)數(shù)8000轉(zhuǎn)以內(nèi)的機床，高速機是指轉(zhuǎn)數(shù)能超過12000轉(zhuǎn)的機床，介于8000—12000之間的機床叫準高速機，此參數(shù)只針對普通機。CNC加工工藝習慣上分三類，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)和進給運行，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，應根據(jù)被加工零件的材料硬度，選用適當?shù)牡毒?，如塑膠，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）應選用進口的鋼刀及國產(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（進給）S（轉(zhuǎn)速）040R612812001500030R512015001700025R50.81515001700020R40.61216001800025R10.81814001600020R0.80.61515001700016R0.40.51214001700012R0.40.5913001800表二（進口白鋼平刀開粗鋁合金45號鋼）刀具深度步距FS鋁鋼鋁鋼鋁鋼02520.818180012002000150002020.81517001100200015000161.50.71217001100220016000121.50.6916001000220016000101.20.571500900230017000810.561500900240017000610.54150080024001700050.80.43120070025001800040.80.42.5100060026001800030.50.3280050028001900020.30.2160040029002000010.20.10.550030030002200表三（白鋼球刀光刀鋁合金45號鋼）刀具加工前留量步距SF鋁鋼鋁鋼鋁鋼020R100.250.150.32200180023001500016R80.250.150.32200180023001500012R60.20.120.252500200026001800010R50.20.120.25250020002600180008R40.20.120.2260023002400160006R30.150.10.15280024002300150004R20.120.080.12300025001800120003R1.50.10.060.0832002600160090002R10.080.050.0635002700130060001R0.50.060.040.04380028001200500表四（鎢鋼球刀光面45號鋼不銹鋼）4/5刀具加工前留量步距SF45號鋼不銹鋼45號鋼不銹鋼45號鋼不銹鋼020R100.20.150.252400240020001800016R80.20.120.252400240020001800012R60.150.10.22600270022002000010R50.150.10.2260027002200200008R40.150.10.15280028002000160006R30.120.080.12300030001800150004R20.10.060.08320032001300100003R1.50.080.050.0635003500100070002R10.070.040.053800380060050001R0.50.050.030.0340004000500400表五（鎢鋼平刀光刀45號鋼不銹鋼）刀具最大切削量最大切深SF45號鋼不銹鋼45號鋼不銹鋼45號鋼不銹鋼45號鋼不銹鋼0160.30.254030160016008007000120.250.23525170017008007000100.20.15302017001700750650080.150.1252018001800650600060.150.1201520002000600500050.10.08151022002200500400040.080.0610723002300400300030.060.055325002500400300020.20.151130003000700500010.150.10.50.535003500600400表六（白鋼平刀光刀鋁合金45號鋼）刀具最大切削量最大切削深度SF鋁合金45號鋼鋁合金45號鋼鋁合金45號鋼鋁合金45號鋼0160.40.2550351700160012008000120.350.240301700160010007000100.30.15352018001700900600080.250.1301520001800900550060.20.1251022001900800500050.150.082082300
