孔: Φ10|9.985|9.970|-0.015|-0.030|0.015|Φ10|
孔: Φ18|18.017|18|+0.017|00.017|Φ18|
孔: Φ30|30.012|29.991|+0.012|-0.009|0.021|Φ30|
轴: Φ40|39.95|39.888|-0.050|-0.112|0.062|Φ40|
轴: Φ60|60.041|60.011|+0.041|+0.011|0.030|Φ60|

2. 1) Xmax= 0.033- (-0.098) =0.131mm
Xmin= 0 - (-0.065) =0.065mm
Tf= | 0.131-0.065 | =0.066mm
2) Ymax= 0 – 0.060 =-0.060mm
Ymin= 0.030 – 0.041 =-0.011mm
Tf= | -0.060+0.011 | =0.049mm
3) Xmax= 0.007- (-0.016) =0.023mm
Ymax= -0.018 – 0 =-0.018mm
Tf= | 0.023 – (-0.018)| =0.041mm
4) Xmax= 0.039 - 0.002 =0.037mm
Ymax= 0 – 0.027 =-0.027mm
Tf=|0.037 – (-0.027)| =0.064mm
5) Xmax= 0.074 – (-0.140) =0.214mm
Xmin= 0 - (-0.030) = +0.030mm
Tf=| 0.214 – 0.030 | =0.184mm
6) Xmax=0.009 – (-0.019) =0.028mm
Ymax= -0.021 – 0 =-0.021mm
Tf=| 0.028 – (-0.021) | =0.049mm
3. (1) Φ50Xmax =0.089mmXmin =0.025mm基孔制、间隙配合
(2)Φ80Xmax =0.250m
