组合机床小型机械动力头的进给运动是由凸轮推动滚子、拨叉,进而使主轴套筒根据加工零件的工艺要求作前后运动来实现的。而对每个小型机械动力头来说,由于被加工对象的不同,其相应的工艺参数(切削速度、走刀量)也是不一样的。所以对于每个小型机械动力头的凸轮都要根据具体的工艺参数要求重新进行设计和制造相应的凸轮曲线。这些工作以往是采用人工的方法进行,这样不但效率低,而且精度差。随着电子计算机应用技术的发展,
The combined machine tool small mechanical power head feed motion is driven by the cam rollers, fork, and then make the spindle sleeve according to the processing requirements of the parts for movement back and forth to achieve. For each small mechanical power head, due to the different objects to be processed, the corresponding process parameters (cutting speed, walking amount) is not the same. Therefore, for each small mechanical power head cam must be based on the specific process parameters required to design and manufacture of the corresponding cam curve. In the past, these efforts were conducted manually, which was not only inefficient but also poor in accuracy. With the development of computer application technology,
