ADAPTIVE CONTROL FOR ACTIVE MANAGEMENT WORKING CYCLE IN infeed plunge grinding

摘要

Adaptive active control for controlling the duty cycle of the cross-feed with the plunge grinding on circular grinding and intragrinding CNC by size commands PAK, comprising the steps of rough and finish grinding and nursing, comprises a PAA comprising a measuring device with inductive transducers, the electronic control unit having a unit supply, a microprocessor, a device for measuring the removal rate allowance, software device for inductive transducers lianerizatsii signals until yvayuschee device with digital display, a device for delivery of information via interface RS-232 or USB from PAK unit in the NC machine tool on the magnitude of the remaining allowance and commands to change the feed of the grinding wheel speed, and characterized in that at all stages of the processing cycle PAK measures the stock removal rate or the stock removal of one or more rotations of the workpiece, compares the obtained value with the value of feed rate of the grinding wheel, and predetermined NC entering the electronic unit PAA via stroystva for subtracting (comparison) feed rate of the grinding wheel and the removal rate of allowance, which is provided with an electronic unit PAC, and if the value of the velocity difference flow range and speed values ​​stock removal exceeds a predetermined PAK value PAK outputs information (the command) in the NC machine tool to increase or reduction in feeding speed of the grinding wheel.
