The core technology of 1 control system and honing of requirement of control analysis system and " protruding is nodded " detect undertake at the same time, the ply of honing basically controls detected grating and PLC to come true jointly by honing oilstone, oil pressure, because the stage amounts to 32EH00M servo to control special PLC series to be able to receive input of 2 channel differential, so need not other change-over circuit, grating feet signal can receive PLC directly, and input the scale down output of servo drive PLC directly at the same time, so that real time detects the absolutely position of machine stage. In actual honing process, because of the circle inside workpiece " protruding is nodded " existence, form a peak value of instant of electric current of motor of honing frequency conversion from this, use systematic core PLC to remember the position when peak value of this electric current is formed, control servo car next here " protruding is nodded " the frequency that honing swings, achieve expectant honing precision, at the same time OK also according to radius of the circle inside grating feet detect, automatic and abrade the ply to set. So this system uses frequency conversion load / correspondence of electric streamline sex concerns, completed pair of circles inside treatment workpiece " protruding is nodded " detect. The stage amounts to V series frequency conversion to measure high-powered drive for Quan Shi, can react accurately quickly the change that gives load current, and the stage amounts to PLC to use communication means electric current of fast sampling transducer is in for the key of this system.

Structure of control of design of 2 control structure refers to a graph 2. Graph 2 servo control a construction 3.
3 strong put oneself in another's position control plan PLC: DVP32EH00M stage amounts to servo special. Transducer: VFD075V43 stage amounts to complete vector control. Servo: 3000W/ stage is amounted to in inertia series. The system is electronic-controlled ark refers to a graph 3. Graph 3 servo are electronic-controlled ark 3.
If the control parameter with crucial design of 4 man-machine interface pursues 4, graph 5, the graph is shown 6 times. Graph Nextpage of homepage of 4 systems monitoring pursues picture of 5 servo parameter 1 setting pursues picture of 6 servo parameter 2 settings 3.
Standards of 5 main techniques (1) machine bore diameter: 3-250mm (2) length of the biggest treatment: 2500mm (3) main shaft rotate speed: 50-600 turns / cent, stepless speed regulation (4) honing speed: 1.
00m-22m/ divides (5) main shaft power: 7.
5KW (6) machine stage power: 3KW (7) oil pump power: Research and development of plan of 400W4 last word runs a result to explain, systematic design is achieved expect design result. This machine tool can process all sorts of data inside round workpiece, from quench cast-iron, hard alloy, pottery and porcelain goes to steel, boron the hard weak data such as aluminium alloy, bronze, organic glass, and of material of other difficult treatment inside round workpiece. Because the stage amounts to PLC/EH series to offer high capacity to drop report to maintain data register (8000) , so control system performance has beardless other peripheral to be able to realize the memory of user craft recipe, the attempers neatly characteristic that convenient spot produces.
