摘　　要：介绍一种汽车组合开关耐久性试验台的计算机数控（ＣＮＣ）系统。该试验台数控系统采用ＩＰＣ作为其控制主机，混合式步进电动机驱动，具有在线测量组合开关触点压降的功能。数控系统具有很高的柔性，组合开关中的各开关的检测档位的位置坐标可由用户以参数输入或以动作示教的方式给出。系统具有型号扩展功能，以方便用户对新型号开关进行检测。该试验台能够满足全系列的汽车组合开关的耐久性试验，并在线可打印统计结果。数控系统软件采用ＧＵＩ（ＧｒａｐｈｉｃＵｓｅｒＩｎｔｅｒｆａｃｅ）技术，人机界面新颖、操作方便。Computer Numerical Control(CNC) system of auto combined switch durability tester is introduced in this paper. The system adopts IPC as its main control computer and is driven by hybrid stepping motor. It has the function of measuring the contact pressure dropping in line. The system has high flexibility,the position coordinate can be given by users. The system enjoys the model extending function so as the users can test the new model switch. The tester can meet the durability test of all series combined switch and the result can be printed. The digital control system adopts GUI technique,its man computer interface is novel and the operation is convenient.
