%X 基于交流电机驱动器,开发了一种数控加工切削参数优化软件及实时监控系统。它主要是由计算机、交流电机驱动器、加工主电机三部分组成。首先,将工件和刀具材料、机床型号等相关信息输入计算机,得到优化的切削参数,并确定电机转速、电流和功率的合理波动范围。在进行切削加工时,该系统可实时地采集主电机的电流数据等进行分析处理。当电机工作电流、功率超出设置的波动范围时(如发生刀具损坏等情况),控制程序会将有关控制指令(如暂停等)发送给交流电机驱动器,使主电机暂停工作。因此,该系统既可优化切削参数,又可实时监控加工主电机的工作电流、转速等信号,确保加工过程稳定、可靠。<br>A real-time monitoring system and corresponding software for optimizing the cutting parameters in CNC machining have been developed by using alternating-current motor driver. This system mainly consists of a computer, an alternating-current motor driver, a prime motor of machining and so on. First the related information including the materials of the work-piece and cutter, the type of machine tool, etc. is input into the computer for optimizing the cutting parameters and determining the reasonable fluctuation range of the motor's rotational speed, current and power. In cutting process, this system can acquire the current/voltage values of the prime motor in real-time for processing and analyzing. When the motor's rotational speed, current and power beyond the predetermined fluctuation range(e.g., tool damage occurrence, etc.); the controlling programs would give the control orders(e.g. pausing, etc.) to the alternating-current motor drive to stop the working of the prime motor. Therefore this system not only can optimize the selection of cutting parameters, and but also can real-time monitor the working currents, rotational speeds, and so on to guarantee a stable and reliable machining process
