To adopt pneumatic feeding mechanism to substitute traditional CAM intermittence drive feeding mechanism are widely applied in press machine.
采用气动技术驱动的送料机构代替传统的凸轮驱动间歇送料机构，在冲压机床中得到了广泛的应用。

In addition, the conception of press Angle of spatial CAM mechanism is discussed and its mathematics model and self-adaptive arithmetic are given also.
另外，利用等距曲面的概念讨论了空间凸轮机构压力角的概念及其自适应求解模型。
