INTELLIGENT ADAPTIVE PROCESS CONTROL SYSTEM FOR METAL CUTTING MACHINE C to spindle active magnetic bearings

摘要

The system includes an adjustable structure in a spindle carrier, the rotary spindle (RSH) 100 which is mounted on supports with active magnetic bearings (AMP) 97 and 98 to control its position through contours registration, control by system 108 NC, disposed in the zone RSH and 100, respectively, in its location area ILA 97 and 98 dual channel control and measuring structure in the form of two pairs of sensors 93 and 94, which is a circuit registration, which channels are organized to perform (interm COROLLARY analog-to-digital converter (ADC) 101 and digital controller 104) commutative communication system 108 NC. Commutative ADC 104 is connected via a digital to analog converter (DAC) 102 and a power amplifier 103 with the windings 97 and 98. The ILA Each pair of sensors 93 and 94 installed in a plane perpendicular to the axis of rotation 100 Pm, offset relative to one another by 90 ° in the circumferential direction. The system comprises a loading means RSH 100. At the end 100 Pm fixed tool holder. As RSH lower support 100 is used Angular AMP 97. The means of loading the rotary spindle 100 is tool holder. Control and measuring structure has two additional arranged in the end zone of the tool holder 96 by sensors installed in the respective plane similar to the sensors 93 and 94 and which are functionally and control means for recording position of the end of the mandrel. This means commutative connected through the ADC 109 to the subsystem 107 for measuring the position of the mandrel end. Commutative subsystem 107 is connected to the system 108 CNC. The system is provided with an electric motor 99. The digital controller 106 Controller 106 controls commutative connected (via ADC 105) with means for registering the speed and angular position Pm 100, made in the form of two sensors 95 mounted in the rear end zone 100 Pm in the corresponding plane, similar to sensors 93 and 94. Digital controller 106 commutative system 108 is connected with the CNC and electric winding 99. The motor 1 ZP f-ly, 21 yl., 1 tab.
