Nc Connecting Plate Punching Machine Control System Design And Development

In the process of machining the steel for bridge, electric, communication and building, the development of the special numerical control equipment is slow, It is mainly because of the level of the numerical control for special equipment is low in our country at present for this case, and the price of the equipment for import is high, Since it has to be the instancy thing to implement the numerical control of our present equipment and lower the cost of the equipment. Based on this aim we sduty the CN computer machines system for platesto product the links in this paper. And we investigate a perfectly method to quickly realize the numerical control for this equipment.The main contents of this paper are given as follows:(I). The programs of upper computer. This program is carry out through VC++. The mainly contents of this part are composed of the following three parts: communication program which make the real-time communication between the host computer and the lower computer come true. It can real-time watch the status of the equipments after it turn on and it can deliver the machining program of the workpiece and the parameters of the equipment to the lower computer; the program of the port to user, the function of this program is to translate the machining program of the workpiece into the injunction codes and then deliver it to the lower computer to control the the equipment to produce the workpiece. At the same time the user can preview the image of the programs of the workpiece, and then check the programs of the workpiece whether fit the ask or not by the image; path optimization, when the number of the hole exceed a pre-given number, we optimize the path that machine the hole group by introducing the genetic algorithms.(II). The control system of the lower computer, Different to the existing CN equipment where the center of the lower computer are mostly to use DSP, In this paper the center of the lower computer we provided is the PLC programmable controller of the Mitsubishi Corporation, In addition it also include the servo systems of the YASAKAWA Corporation and various sensors etc. The center technique of this part is write the process control software of the CN computer machines system for plates by using ladder chart in the PLC. This software can make the equipment operation by itself according to the program of the workpiece that the user give. The user can also operate...
