一、前言微电子技术及信息技术的飞速发展,使机床技术进入了自动化、集成化的阶段。加工中心、CNC机床的普及和应用,FMC、FMS的出现,使生产得到了大幅度提高。这就要求机床本身具有监控能力,能在不断变化的运行状态中,对刀具的磨损和破损,刀具的寿命进行监视,对工件的精度进行监视和适时测量补偿。要达到这一目的,就需要给机床配上接触传感器。这种 First, the preface The rapid development of microelectronics and information technology, machine tools technology has entered an automated, integrated stage. Machining centers, the popularity of CNC machine tools and applications, the emergence of FMC, FMS, so that production has been greatly improved. This requires the machine itself has the ability to monitor, in changing operating conditions, the tool wear and tear, the life of the tool to monitor the accuracy of the workpiece to monitor and timely measurement and compensation. To achieve this goal, we need to match the machine with touch sensors. This
