| 摘 要： | 可展曲面只有一族直母线，反之，只有一族直母线的直纹面是否可展尚未见文献提及，而工程中，尤其数控加工常遇到这一问题，本文在引用已有判据基础上，给出了只有一族直母线的不可展的多个工程常用直纹面，为数控加工方案选择提供了参考。

| Abstract: | Curve surface which can be expansed has only one group of generatrix. However, there is no any report about whether a curve surface with only one group of generatrix can be expansed. This problem often appears in digit control machining. A few ruled surfaces with only one group of generatrix, which can not be expansed and are often used in engineering, are given out in this paper. This can be used as an reference in selecting machining process. |
