与传统砂轮相比，超硬磨料砂轮需要不同的修整策略。需要一种检测修整器和砂轮之间接触的方法。本文介绍了三种用于敷料接触检测的传感器。第一个传感器测量修整主轴的交流电机消耗的功率。第二个传感器是压电堆。压电元件的电压在外部修整力下发生变化。第三种是声发射传感器。本文介绍了传感器的原理和设计，比较了传感器信号，并评估了三种工业方法在超硬磨料磨削中的适用性。

SUPERABRASIVE GRINDING WHEELS REQUIRE DIFFERENT DRESSING STRATEGIES COMPARED TO CONVENTIONAL WHEELS. A METHOD FOR THE DETECTION OF THE CONTACT BETWEEN DRESSER AND GRINDING WHEEL IS NECESSARY. THREE SENSORS FOR CONTACT DETECTION AT DRESSING ARE DESCRIBED. THE FIRST SENSOR MEASURES THE POWER WHICH IS CONSUMED BY THE AC-MOTOR OF THE DRESSING SPINDLE. THE SECOND SENSOR IS A PIEZOELECTRIC STACK. THE VOLTAGE OF THE PIEZO ELEMENT CHANGES UNDER EXTERNAL DRESSING FORCES. THE THIRD IS AN ACOUSTIC EMISSION SENSOR. THIS PAPER DESCRIBES PRINCIPLE AND DESIGN OF THE SENSORS, COMPARES THE SENSOR SIGNALS, AND EVALUATES THE APPLICABILITY OF THE THREE METHODS FOR INDUSTRIAL USE IN SUPERABRASIVE GRINDING.
