METHOD AND DEVICE FOR PREVENTING THERMAL DAMAGE OF WORKPIECES DURING GRINDING

摘要

A method and a device for preventing thermal damage of workpieces during grinding are provided. According to the inventive method a two-flank rolling test is performed via a master pinion before the grinding process. The result of this two-flank rolling test is then used to calculate an effective maximum amount of material to be removed. Based on a permissible amount of material to be removed per time unit for the respective grinding tool a permissible rate of advancement of the grinding tool is calculated with the determined effective maximum amount of material to be removed. The calculated rate of advancement is then fed into the machine control unit. The device is provided with a master pinion for performing the two-flank rolling test, a rotatory measuring device connected to the master pinion for measuring rotatory deviations, and a translatory measuring device connected to the master pinion for measuring translatory deviations, whereby rotatory and translatory deviations are used to determine an effective maximum amount of material to be removed during grinding. Light-emitting diodes are visually indicating the respective maximum effective amounts to be removed may also be provided.
