加工中心刀具切削参数CNC加工应分为低速加工和高速加工两大类，普通机是指机床转数8000转以内的机床，高速机是指转数能超过12000转的机床，介于8000—12000之间的机床叫准高速机，此参数只针对普通机CNC加工工艺习惯上分三类，开粗，中光（半精），光刀（精铣），一般以为开粗宜用较大刀具（飞刀和端铣刀）并用较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则以轻切削（小切深,，小步距）配合较高转数和进给运行，以求得完美的表面精度光平面用端铣刀（或圆角刀）和飞刀，光垂直壁用端铣刀，光曲面用球刀（或圆角刀）在加工过程中，应根据被加工零件的材料硬度，选用适当的刀具，如塑胶，木料等可选用国产的白钢刀铜，铝材以及硬度在洛氏38度以内的钢材（如45号钢,王牌料）应选用进口的钢刀及国产优质的钢刀硬度较大的材料（如淬硬模具钢）应优先选用合金刀，镀钛刀或钨钢刀本参数针对普通CNC机床，针对开粗和光刀分别对各种刀具加以说明（飞刀，白钢，端铣刀，钨钢平铣刀，白钢球刀，钨钢球刀）因加工素材繁多，本表仅以富有代表性的铝合金，45号钢，不锈钢加以说明表一（飞刀开粗以45号钢为例）刀具种类深度（毫米）步距F（进给）S（转速）04OR61281200150003OR512015001700025R50.8151500170002OR40.61216001800025R10.8181400160002ORO.80.61515001700C16R0.40.51214001700C12R0.40.5913001800表二（进口白钢平刀开粗铝合金45号钢）刀具深度步距FS铝钢铝钢铝钢C2520.8181800120020001500C2020.8151700110020001500C161.50.7121700110022001600C121.50.691600100022001600CIO1.20.57150090023001700C810.56150090024001700C610.54150080024001700C50.80.43120070025001800C40.80.42.5100060026001800C30.50.3280050028001900C20.30.2160040029002000C10.20.10.550030030002200表三（白钢球刀光刀铝合金45号钢）刀具加工前留量步距SF铝钢铝钢铝钢C20R100.250.150.32200180023001500C16R80.250.150.32200180023001500C12R60.20.120.252500200026001800C10R50.20.120.252500200026001800C8R40.20.120.22600230024001600C6R30.150.10.152800240023001500C4R20.120.080.123000250018001200C3R1.50.10.060.08320026001600900C2R10.080.050.06350027001300600C1R0.50.060.040.04380028001200500表四（钨钢球刀光面45号钢不锈钢）刀具加工前留量步距SF45号钢不锈钢45号钢不锈钢45号钢不锈钢02OR1O0.20.150.252400240020001800016R80.20.120.252400240020001800012R60.150.10.2260027002200200001OR50.150.10.2260027002200200008R40.150.10.152800280020001600C6R30.120.080.123000300018001500C4R20.10.060.08320032001300100003R1.50.080.050.0635003500100070002R10.070.040.0538003800600500C1R0.50.050.030.0340004000500400表五（钨钢平刀光刀45号钢不锈钢）刀具最大切削量最大切深SF45号钢不锈钢45号钢不锈钢45号钢不锈钢45号钢不锈钢C160.30.25403016001600800700C120.250.2352517001700800700C100.20.15302017001700750650C80.150.1252018001800650600C60.150.1201520002000600500C50.10.08151022002200500400C40.080.0610723002300400300C30.060.055325002500400300C20.20.151130003000700500C10.150.10.50.535003500600400表六（白钢平刀光刀铝合金45号钢）刀具最大切削量最大切削深度SF铝合金45号钢铝合金45号钢铝合金45号钢铝合金45号钢C160.40.255035170016001200800C120.350.24030170016001000700C100.30.15352018001700900600C80.250.1301520001800900550C60.20.1251022001900800500C50.150.0820823002000700450C40.50.321.22600220012001100C30.30.21.51270024001000800C20.250.210.528002500800500C10.20.150.80.330002600600400。
