項(xiàng)目八橢圓蓋的編程與加工任務(wù)8.3

編寫零件加工程序項(xiàng)目八018.3.1數(shù)值計(jì)算根據(jù)已知條件M30×1.5㎜，計(jì)算可得：d外圓＝d－0.2＝30－0.2＝29.8㎜d1實(shí)際＝d－1.3P＝30－1.3×1.5＝28.05㎜（1）螺紋部分尺寸的計(jì)算（2）橢圓曲面尺寸的計(jì)算

該橢圓焦點(diǎn)在Z軸，用橢圓的標(biāo)準(zhǔn)方程編程，以z為自變量，x為應(yīng)變量，通過公式（8-1）可得：將a＝24,b＝40帶入，可得：粗車外輪廓精車外輪廓車螺紋切斷粗車橢圓曲面精車橢圓曲面熱處理后續(xù)工序橢圓蓋工序（3）橢圓蓋零件左端輪廓走刀路線與數(shù)值計(jì)算點(diǎn)位左端外輪廓走刀路線為：P1→A1→①→②→③→④→⑤→⑥→⑦→A1→H1編程原點(diǎn)O對(duì)刀點(diǎn)O安全點(diǎn)P1X坐標(biāo)值0.00.0100.0Z坐標(biāo)值0.00.0100.0換刀點(diǎn)H1循環(huán)起點(diǎn)A1X坐標(biāo)值100.052.0Z坐標(biāo)值100.02.0（3）橢圓蓋零件左端輪廓走刀路線與數(shù)值計(jì)算點(diǎn)位左端外輪廓走刀路線為：P1→A1→①→②→③→④→⑤→⑥→⑦→A1→H1①②③④X坐標(biāo)值26.029.829.834.98Z坐標(biāo)值0.0-2.0-16.5-16.5
