| 摘 要： | 准确判断刀具的切入和切出状态是自动化加工系统的迫切要求,而用加速度计来传感这种信息是一种有益的尝试。本文分析了切削振动信号在此过渡过程中的变化规律以及带通滤波器对信号传输过程的影响。根据状态变化时出现的两种信号特征,微机系统能够实现可靠的检测。

| Abstract: | There is an urgent requirement to identify the entry and exit states of the turning tool correctly in automatic machining system,and it is a useful attempt to use accelerometer as sensor for this job. In this paper, the change pattern of the cutting vibration signal during the transient processes and the effect of the parameters of band pass filter on the signal transmission are analyzed. In accordence with two kinds of signal characteristics appearing before, at and after the state transition, the reliable in-process detecting can be realized in the microcomputer-based system. |
