PC机能按照梯形图或工艺流程图来编制程序,并把程序存入贮存器中,对开关量进行往复自动控制。它把继电器控制的简单易懂、操作简便及价格便宜等优点,同计算机的功能完备、灵活性和通用性强等优点有机地结合起来,得到了广泛的应用,并取得了显著的经济效益。以下介绍我们采用了日本三菱电机公司的FI-40MR型PC机控制一台曲轴钻中心孔铣两端画专用机床(简称曲轴专机)。曲轴专机是我厂自制的一台机床,它用来加工195s
PC function in accordance with the ladder or process flow chart to program, and the program stored in the memory, the switch to the reciprocating automatic control. It relays the control easy to understand, easy to operate and cheap, and other advantages, with the full-featured computer, flexibility and versatility and other advantages of organic combination, has been widely used, and achieved significant economic benefits. The following describes the use of Japan’s Mitsubishi Electric Corporation’s FI-40MR-type PC control of a crankshaft center hole drilling both ends of the painting machine (referred to as crankshaft plane). Crankshaft plane is a machine made by our factory, which is used to process 195s
