【正文】 創(chuàng)建刀具 生成加工軌跡在加工中我們一般用到的加工方法有四種：mill planar（一般平面銑） 、mill contour（型腔銑） 、fixed contour（固定軸銑） 、drill（鉆、鏜孔） 。在該零件的加工中，我們也用到上述四種加工方法。在這里我們例舉件一薄壁a 的加工進(jìn)行說(shuō)明，薄壁 a 分為內(nèi)型腔和外輪廓，其加工路線是粗加工、半精加工、精加工。內(nèi)型腔加工粗加工時(shí)選擇并輸入圖 4圖 4圖 45 的內(nèi)容，選用一般平面銑，刀具選擇 φ16 的。 圖 43 確定加工內(nèi)容圖 44 進(jìn)給和速度 該零件所有加工軌跡完成后如圖 45 所示，并要對(duì)其軌跡進(jìn)行 3D 仿真加工，看看還有哪些地方未加工到。是否產(chǎn)生刀具干涉，軌跡是否需要編輯，最后確定后即完成加工軌跡生成。圖 45 刀軌 生成部分程序 所有加工軌跡完成后，要對(duì)其進(jìn)行后置處理，生成加工程序。首先選擇要輸出程序的項(xiàng)，再點(diǎn)擊“輸出CLSF” ，設(shè)置好參數(shù)如圖46自動(dòng)即生成程序。圖 46 后處理 例舉自動(dòng)生成的程序 本節(jié)只例舉圓弧曲面的自動(dòng)加工程序，其他程序見(jiàn)附錄。如圖 47 圖 47 圓弧曲面加工自動(dòng)生成程序如下：N0010 G40 G17 G90 G70N0020 G91 G28 :0030 T00 M06N0040 G0 G90 S800 M03N0050 G43 H00N0060 G1 M08N0070 N0080 N0090 N0100 N0110 N0120 Z.3426N0130 Z.3278N0140 Z.3077N0150 Z.2942N0160 N0170 N0180 N0190 N0200 N0210 Z.2749N0220 N0230 Z.2848N0240 Z.2942N0250 Z.3078N0260 Z.3279N0270 Z.3428N0280 Z.3669N0290 Y N0300 Y N0310 Z.3358N0320 Z.3174N0330 Z.2922N0340 Z.2745N0350 Z.2614 N0360 Z.2442N0370 Z.2362N0380 Z.2351N0390 N0400 N0410 N0420 Z.2614N0430 Z.2745N0440 Z.2922N0450 Z.3174N0460 Z.3357N0470 Z.3664N0480 N0490 N0500 N0510 Z.3117N0520 Z.2838N0530 Z.2633N0540 Z.2472N0550 Z.2245N0560 N0570 N0580 N0590 Z.2117N0600 Z.2245N0610 Z.2472N0620 Z.2633N0630 Z.2838N0640 Z.3117N0650 Z.3319N0660 Z.3663N0670 YN0680 Z.3296N0690 Z.3064N0700 Z.2728N0710 Z.2485N0720 Z.2301N0730 Z.2156N0740 Z.2041N0750 Z.1888N0760 Z.1819N0770 Z.1813N0780 N0790 N0800 N0810 N0820 Z.2041N0830 Z.2156N0840 Z.2301N0850 Z.2485N0860 Z.2728N0870 Z.3064N0880 Z.3297N0890 Z.3664N0900 N0910 N0920 N0930 Z.3615N0940 N0950 Z.3353N0960 N0970 Z.2795N0980 Z.2469N0990 Z.2231N1000 Z.2052N1010 Z.1911N1020 Z.1799N1030 N1040 N1050 N1060 N1070 Z.1577N1080 Z.1583N1090 N1100 Z.1799N1110 Z.1911N1120 Z.2052N1130 Z.2231N1140 Z.2469N1150 Z.2795N1160 Z.302N1170 Z.3353N1180 Z.3171N1190 Y N1200 N1210 Y N1220 Y N1230 Z.3101N1240 N1250 N1260 Z.2775N1270 Z.2554N1280 Z.2236N1290 Z.2022N1300 Z.1825N1310 Z.1687N1320 Z.1578N1330 Z.1432N1340 Z.1367N1350 Z.1361N1360 N1370 N1380 N1390 N1400 Z.1578N1410 Z.1687N1420 Z.1825N1430 Z.2022N1440 Z.2236N1450 Z.2554N1460 Z.2775N1470 Z.3103N1480 Z.2867N1490 Z.2546N1500 Z.2331N1510 Z.2021N1520 Z.1794N1530 Z.1619N1540 Z.1482N1550 Z.1375N1560 N1570 N1580 N1590 N1600 Z.1163N1610 Z.1168N1620 Z.1232N1630 Z.1374N1640 Z.1481N1650 Z.1618N1660 Z.1792N1670 Z.2022N1680 Z.2327N1690 Z.2541N1700 Z.2857N1710 Z.2803N1720 Y N1730 Z.2337N1740 Z.2127N1750 Z.1824N1760 Z.1603N1770 Z.1432N1780 Z.1297N1790 Z.1191 N1800 Z.1049N1810 Z.0986N1820 Z.0981N1830 N1840 N1850 N1860 Z.1192N1870 Z.1298N1880 Z.1433N1890 Z.1604N1900 Z.1825N1910 Z.2129N1920 N1930 Z.2654N1940 Z.2462N1950 Z.2155N1960 Z.1946N1970 Z.1649N1980 Z.1432N1990 Z.1264N2022 Z.1027N2022 N2020 N2030 N2040 N2050 Z.0824N2060 Z.0887N2070 Z.1027N2080 Z.1264N2090 Z.1432N2100 Z.1649N2110 Z.1946N2120 Z.2155N2130 Z.2462N2140 N2150 Z.199N2160 Z.1784N2170 Z.1489N2180 Z.1276N2190 Z.1111N2200 Z.0879N2210 Z.0741N2220 Z.0679N2230 Z.0674N2240 N2250 N2260 N2270 Z.0879N2280 Z.1111N2290 Z.1276N2300 Z.1489N2310 Z.1784N2320 N2330 N2340 Z.2137N2350 Z.1842N2360 N2370 Z.1348N2380 Z.1136N2390 Z.0973N2400 Z.0745N2410 N2420 N2430 N2440 N2450 Z.0548N2460 Z.0609N2470 Z.0745N2480 Z.0973N2490 Z.1136N2500 Z.1348N2510 Z.164N2520 Z.1842N2530 Z.2137N2540 Z.2022 N2550 Z.1711N2560 Z.1512N2570 Z.1224N2580 Z.1015N2590 Z.0852N2600 Z.0625N2610 Z.0491N2620 Z.0431N2630 Z.0426N2640 N2650 N2660 N2670 Z.0625N2680 Z.0852N2690 Z.1015N2700 Z.1224N2710 Z.1512N2720 Z.1711N2730 Z.2022N2740 Z.1884N2750 Z.1597N2760 N2770 Z.1116N2780 Z.0909N2790 Z.0749N2800 Z.0523N2810 N2820 N2830 N2840 N2850 Z.0329N2860 Z.0389N2870 Z.0523N2880 Z.0749N2890 Z.0909N2900 Z.1116N2910 N2920 Z.1597N2930 Z.1884N2940 Z.1782N2950 Z.1498N2960 Z.1304N2970 Z.1023N2980 Z.0818N2990 Z.0659N3000 Z.0436N3010 Z.0303N3020 Z.0244N3030 Z.0239N3040 N3050 N3060 N3070 N3080 Z.0436N3090 Z.0659N3100 Z.0818N3110 Z.1023N3120 Z.1304N3130 Z.1498N3140 Z.1782N3150 Z.1699N3160 Z.1415N3170 Z.1222N3180 Z.0943N3190 N
