One, SINUMERIK840D of performance of system of SINUMERIK840D numerical control is 20 centuries of Xi Menzi company the system of high-powered numerical control that 90 time roll out. It holds the 3 CPU construction of SINUMERIK880 of before Xi Menzi two acting systems and 840C: Man-machine communication CPU (MMC-CPU) , the number controls CPU (NC-CPU) and but CPU of controller of process designing logic (PLC-CPU) . 3 parts divide the work each other already on the function, each other is support. On physical structure, NC-CPU and PLC-CPU close for an organic whole, synthesis is in NCU (NumericalControlUnit) in, but mutual on logistic function independence. Opposite at before a few acting systems, SINUMERIK840D has the following characteristics: (1) digitlization drive is in SINUMERIK840D, the interface signal of numerical control and drive is digital amount, pass interface of drive bus line, hang receive module of each axis drive. (2) the axis accuses dimensions to be able to match 31 axes at most greatly, can match 10 main shaft among them. (3) the linkage treatment that can realize SINUMERIK840D of 5 axes linkage to be able to realize axis of X, Y, Z, A, B5, curved surface of any three dimensional space can be machined. (4) operating system window changes SINUMERIK840D to use Windows95 to regard an operation as platform, make an operation simple, agile, easy control. (5) software content abounds a function powerful SINUMERIK840D can realize treatment (Machine) , parameter is installed (Parameter) , service (Services) , diagnose (Diagnosis) reach installation to start (Start-up) wait for function of a few old software. (6) have if the spot uses card of PC adapter, MODEM,diagnose a function remotely, realize SINUMERIK840D and communication of different region PC through line, finish modification PLC to diagnose a function remotely program and condition of monitoring machine tool. (7) software of perfect SINUMERIK840D system divides protective function to serve manufactory of class, machine tool for Xi Menzi 7 software such as domestic class, final user class protect grade, make a system more safe but * . (8) hardware height is compositive changed system of SINUMERIK840D numerical control to use a large number of super large-scale integrated circuit, those who improved hardware system but * sex. (9) modular the soft hardware system that designs SINUMERIK840D differentiates according to function and action for different functional module, make systematic join more simple. (10) inside PLC of the outfit inside the system of numerical control of PLC system SINUMERIK840D that installs high capacity is the biggest can match 2048 inputs and 2048 output, and used agreement of communication of interface of much dot of Profibus spot bus line and MPI, reduced spot wiring greatly. (11) PC changes system of SINUMERIK840D numerical control is a numerical control system that is based on PC. 2, its main function part introduces below structure of hardware of system of SINUMERIK840D numerical control. 1.

The number controls unit NCUNCU (NumericalControlUnit) the control center that is system of SINUMERIK840D numerical control and information processing center, the arithmetic manipulation of system of the orbit operation such as the linear interpolation of numerical control system, circular arc interpolation and control, PLC and logistic operation are completed by NCU. In SINUMERIK840D, NC-CPU and PLC-CPU use hardware unifinication structure, synthesis is in NCU. 2.

The main effect that unit MMC-CPUMMC-CPU handles in the center of man-machine communication is to finish machine tool and outside to reach with the communication between PLC-CPU, NC-CPU, hard disk is taken inside, program of system of storage of in order to, parameter. 3.

The action of OP of face plate of operator of OP031 of operator face plate is: Indication data reachs a figure, offer man-machine to show an interface; Editor, modification program reachs parameter; Realize soft function operation. There is the face plate of 5 kinds of operators such as OP031, OP032, OP032S, OP030 and PHG in SINUMERIK840D. Among them, OP031 is the operator face plate that often uses. 4.

The main effect of MCPMCP of face plate of machine tool operation is the operation of the of all kinds hard function key of machine tool of the numerical control that finish. Basically have the following kind operation of 6 hard function key. (1) optional operation mode has area of operation mode key the mode of 4 kinds of operations such as JOG, MD, TEACHIN and AUTO. (2) area of axial choice key realizes axial choice, the dot of the axis that finish moves feed, answer reference point and increment feed. (3) use for the user from definition key area, the data that passes PLC piece the connection of implementation and system, the special function that manufacturer of the machine tool that finish asks. (4) switch of fold of main shaft of area of main shaft operation, 150% fold of 0 ～ repair rotate speed of implementation main shaft tone. What pushbutton implements system of main shaft drive stop to rise since main shaft stop, the pulse that controls system of main shaft drive commonly can make with drive can. (5) switch of fold of axis of feed of area of feed axis operation, 200% fold of 0 ～ repair rotate speed of implementation main shaft tone. What pushbutton implements system of feed axis drive stop to rise since feed axis stop, the pulse that controls system of feed axis drive commonly can make with drive can. (6) what emergency stop button realizes a machine tool is urgent jockey, the pulse that cuts off feed axis and main shaft can make with drive can. 5.

I/RF advocate power source module advocate power source module is main the function is implementation commutate and voltage promotion function. 6.

It includes drive system system of main shaft drive and feed drive system two parts. CNC Milling CNC Machining
