METROLOGICAL PROVISION OF ACCURACY OF ACTIVE CONTROL DEVICES IN THE PROCESSING PROCESS

Abstract

The article considers the methods of increasing the accuracy of dimensional parameters of parts by identifying the mechanism of relationships of design and technological features of the parts being processed, and metrological accuracy of automatic control and monitoring of the metalworking process. The method of determining the error of readings and other accuracy characteristics of devices for grinding machines using a rigid rack provided with a support table and a bracket for mounting the measuring instrument under test and an exemplary digital indicator, which indicates the movement of the table. It is established that a significant reserve for improving the accuracy of machining on metalworking machines is the use of an automatic control system for the initial parameter with the use of an appropriate active control device. The device must have an analog or discrete output and certain dynamic properties that determine the dynamic properties of the entire system and the allowable error.
