ADAPTIVE CONTROL SYSTEM FOR PROCESS OF MONITORING OF OPERATION OF METAL CUTTING MACHINE TOOL Russian patent published in 1995 - IPC

FIELD: machine tool building. SUBSTANCE: system, including three meters 1,2,3, three memory units 4,5,6, three comparators 8, 9,10, three scaling units 12,13,14, two setters 16,17, two adders 19, 20, two delay unit 21, 22, two units 23,24 for determining module, two comparators 25,26, two switches 28,29, the arithmetical unit 32, the extrapolator 23, a differentiator 36, the low-frequency filter 37, the timer 38 and the switching-over unit 39, also has the dispersion meter 41, the identifying unit 40, second and third extrapolators 34, 35, third and fourth setters 18,42, third comparator 27, third and fourth switching 30, 31, fourth comparator 11, fourth scaling unit 15 and fourth memory unit 7. Such structure allows to take into account statistical interconnections between the meters upon monitoring a cutting process by different ways. EFFECT: enhanced accuracy of controlling a process of monitoring cutting operations. 1 cl, 7 dwg
