Summary: The orbit motion that PCB cut system is a kind of model controls a system, it is printed circuit the crucial facility that board essence cuts treatment closely. Change to miniature as electronic product, miniaturization way develops, printed circuit board the line to cut equipment, the performance demand that wide, line spurs the line is higher and higher. PCB cut system is relying on gender, system toward high speed, high accuracy, Gao Ke compositive change, intelligence changes the fashion with high rate to develop, here, recommend use numerous to promote the ADT-8948A1 of own research and development motion controls card, develop the PCB cut system that leans into the high-powered, Gao Ke that uses easily simply, the requirement that can satisfy pair of PCB cut industries to wait to athletic pilot high speed, high spirit. One, the foreword swift and violent development as computer technology and IT, traditional special model enclosed system gradually to quick diversiform type numerical control the system transforms, as the energy that uses a field labour is changed and specialization, in special domain, rise further to the work efficiency of numerical control system and precision requirement, outspread in the numerical control system of quick much style the equipment of special numerical control with an all sorts of efficient major, develop in resolving agile diversity and concentrated and efficient contradiction, appeared all sorts of current system platform and special system platform, PCB cut system is delayed by general cut domain namely extend the system of special numerical control with a kind of is aimed at PCB perforation and cut technically to have efficient job efficient major that come. As the wide application of the rapid development of industry of our country electron and integrated circuit, to pressworking the demand of form of precision of circuit board cut, line is higher and higher. To satisfy printed circuit of pair of high speed high accuracy board the demand of treatment, numerous go up in WINDOWS system platform to promote, the PCB cut that developed the PCI that is based on ADT-8948A1 motion to control card to insert a PC directly to insert groove controls a system, this system has traversal speed precision of fast, control a lot of advantage such as stability of tall, function, through many printed circuit board practice of processing factory home uses a proof, this system is had use easily simply, efficient, high spirit, high reliability. 2, the design 　 that is based on control to block athletic system 1, ADT-8948A1 blocks brief introduction 　 (1) , 32 PCI bus line, 　 of Plug and Play (2) , all inputs, output all uses smooth Ou to keep apart, strong 　 of interference rejection sex (3) , 4 axes servo / the pace is controlled into electric machinery, can control independently already, each other does not affect 　 (4) , the frequency error that pulse outputs is less than 0.

1% 　 　 (5) , frequency of output of the biggest pulse is 4MHz 　 　 (6) , pulse outputs usable odd pulse (pulse + direction) or double pulse (pulse + pulse) means 　 (7) , 4 axes all have positional feedback to input, 32 computation, limits of the biggest computation - 2, 147, 483, 648 ～ + 2, 147, 483, 647 (8) , linear or S curve undertakes adding / decelerate, asymmetrical add point-blank / retarded motion 　 (9) , 2-4 axis is linear interpolation 　 (10) , 　 of interpolation of circular arc of CW, CCW (11) , function of usable and successive interpolation, 　 of 　 of 2MHz of frequency of speed of the biggest drive (12) , every axis has 2 to compare register 32 times to be used at logical place tally the positional volume of tally of real perhaps position is compared, can use at software spacing 　 (13) , all sorts of signal that can receive servo motor driver, if coder Z believes signal, reach the designated position the 　 such as signal, alarm signal (14) , every axis has 3 STOP signal, dot of usable Yu Yuan is searched for, coder Z searchs for 　 (15) , speed 　 can be changed in real time in motion (16) , can numerate in real time in motion Nextpage of condition of speed of logical place, real position, drive, acceleration, drive, a 　 all can serve as outside dividing 2 spacing signal (19) , use with I/O, digital output can be used at servo open, servo calls the police the signal 　 such as restoration (20) , each input end that inputs signal equips integral filter, can the filter function that set inputs signal which turns into effective or invalid, the time constant of filter can choose a support to be used in a system from 8 sort amount to 16 control to block 　 (21) , the 　 of 　 of operating system; such as supportive DOS, WINDOWS95/98/NT/2000/XP, WINCE 2.

The program of software of system of implementation numerical control of PCB cut system falls in Windows2000, use Visual C++6.

What 0 object-oriented languages undertake is based on package is modular development, use teach means to undertake designing to PCB cut system. The system used 3 motion to control an axis, high speed of a main shaft is motor, 3 servo electric machinery, 2 pass in and out that put PCB machine platform. Main function has the system: Of machine program teach generate and revise, motion tests a system, the location that MARK chooses and correctional, change a knife automatically, cutting tool service life manages, treatment amount parts accumulative total, main shaft uses the accumulative total of time, the system is judged unusually and call the police, the PCB that can realize cut of or so platform to differ board. 3.

The main function of PCB cut system teachs a type: Have bit of bore, sharp cut, l cut, u cut, circular arc cut, circular cut. Form process designing: Teach generate all sorts of cut data or revise / correctional cut data. Treatment: Will teach generated data, carry the kind that interpolation moves, bring 3 servo into play to cooperate to move all sorts of the process that athletic contrail has PCB cut. Recursive origin: Return to the operation of the mechanical origin of platform, ensure the precision that machines every time. Method imitate: Imitate machines a process, be searched in order to facilitate and the positional precision in process of cut of test and verify. I O checks: The input outputs test and the athletic test of 4 axes. Systematic set: The set of parameter is mixed related the system revise save. Change a knife: Systematic cutting tool reachs service life, undertake changing the course of the knife. CCD is correctional: The data deviation between correctional CCD counterpoint and systematic cut. Information clew: Clew unit process of cargo bandling or systematic warning information 3, the article uses the last word Shenzhen is numerous the numerical control system that controls card to be control platform to promote the ADT-8948A1 four-axle servo of limited company of numerical control technology to move, be based on modular the software design of package, friendly man-machine interface, agile system configuration comes true in WINDOWS operating system, raised operation speed of the system and control precision at the same time. This system function is powerful, the real time such as control of achievable interpolation operation, position is controlled, was become successfully already by development PCB cut machine. Success application processes a trade at PCB, for PCB treatment rose to machine character, shortened treatment is periodic, improved the quality of circuit board and treatment efficiency. CNC Milling
