Design On Multifunctional Machine Tool Assistant Controller For Actualizing Integration-Manufacture

The essential objective of integrated manufacture system is to realize the integrated manufacture of pivotal product, attain to raise the product quantity, compress the ability of research to manufacture the period, fast contingency market, by cooperating of soft and hardware's condition, applying the information technique, making use of the high performance of number control equipments. The CIMS experienced the 70's to the 80's, the stage that regarding the information storage as the characteristic, the stage of becoming the characteristic with the processing integration after 80's, the stage of becoming the characteristic with the business enterprise integration to the 80's end go to now, the CIMS entered a stage that develop quickly. All had the new contents on the CIMS content and concepts. The business enterprise integration will be the new development stage of CIMS this century. Along with the technical development of the calculator technique and information, having the forerunner's technique theories of production and manufacturing to put forward continuously, each nation and business enterprise throw in a great deal of funds, manpower and material resources to carry on the research and developments mutually. With the calculator technique supporting, the CIMS is a point of the international community research, in the guide line of the CIMS philosophy, Agile manufacturing, Concurrent engineering, Virtual manufacturing and Green manufacturing are hot points of the research. To compare with this kind of frenzied advanced theories researching, the technique that really becoming the actuality and creating the profits completely is not much. Investigate its reason, mostly because of the condition distance from the existing production to manufacturing theories is very greatly .The production of these forerunners makes the way to need to throw in the funds many, time long, the risk is high, just a kind of ideal production manufacturing mode. For pursuing the profits of the manufacturing enterprise, take into account the economic profits repay rate, funds, technique etc comprehensive factor, the theories becomes the actuality to exist the very big margin. In our country, have a great deal of small enterprise; carrying out the above advanced manufacturing mode is also knotty. Although these small business enterprise own numerical control, processing center, the business enterprise that have links tool machine and calculators through a network, controlling the numerical control tool machine and processing center, carry on the control with the calculator logarithms, form FMS or the FMS of the first steps, but talk not up" nimble". Textual Pseudo-enterprise regrouping product manufacturing project is in the above-mentioned circumstance to be put forward, the purpose is further raises the enterprise and plat's integration under the condition of existing economic technique, Making the forerunner's production manufacturing theories have the real realization to some extent. The Pseudo-enterprise regrouping is a production mode, leading of the CIMS philosophy, According to our country economic, technique, produce manufacturing condition, making the resources of production manufacturing to further integration, and have the adaptability and possibilities. This text's definition of Pseudo-enterprise regrouping: The temporary business enterprise constitute within the scope of certain region of independent manufacturing business enterprise unite. By the economic agreement, carry on the share of technique, manpower, equipments, cost, market. Make each independent manufacturing business enterprise carry on repair with each other in each one. See from exterior, Pseudo-enterprise regrouping is the each independent production manufacturing enterprise. Being to have the market need, independent production manufacturing enterprise will make unite production ability, oneself of the enterprise production manufacturing ability, oneself production project facing the market need that makes use of the conglomerate resources, give customer or face the need. the customer consult the project, according to the completing time, technique, the funds need ,comprehensive factor etc of the mission , hand over mission to a certain independent production manufacturing enterprise.See from inner part, in Pseudo-enterprise regrouping, enterprise that getting hold of or putting forward the production mission will to be the leadership enterprise. According to the technique condition, measure the ground Area condition, by the economy consultation, in many ways factor etc assures the member of regrouping enterprise to complete the mission. The leadership enterprise will distribute the mission or the equipments, technique resources, and complete the production mission. Under Pseudo-enterprise regrouping mode, although carry on the regroup of equipments and cars, reduce the equipments and technical repetitions investment, but When increase the regrouped machine tool, the control of computer to machine tool will increase laying bus work. When production is over, the temporary plant disintegrate, this part laying bus again idle .At this kind of circumstance, this text designed a kind of Multifunctional machine tool assistant controller and can make up these weaknesses, it is a powerful tool to carry out the plant integration on the guiding of CIMS philosophy. The Multifunctional machine tool assistant controller is different from the simple communication interface; it is man-machine interface unit under the condition of above-mentioned. It completes originally the work of the original communication interface as well as develops the new function module according to the actual circumstance. Adapt dynamic state's production manufacturing of many enterprises consociation inside a district particularly. The text using the SPI bus expand the bus of 51 series, replace parallel bus of 51 by the serial bus, get over the limit of 51 series'pins. Overcome 51 series to lead the limit of the feet resources. The method to realize the SPI bus in 51: For the 51 series without SPI bus, can use soft to imitate the SPI operation, include the serial clock, the data importation and data exportations. They have different clock for different periphery chip of serial interface. For machine of importation( receive) data in the SCK rising and the exportation( send out) data at descend, set the original state of serial clock's exportation—P1.1 as 1,and after allowing interface set P1.1 as 0. Thus, at the time of MCU outputting 1 bit SCK clock, will make interface chip go left shift, thus output 1 data to the P1.3 of 51 series(MISO line of imitate MCU),henceforth set again P1.1 as 1, make the MCS-51 series outputs 1 data( first for high) to the serial interface chip. Thus, imitate 1 data importation and exportation then come to complete. The hardware carries on designing by the modularization method with the Orcad, adopting assembly language and CX51 by mixing programmer develops the soft. The KEIL Cx51 is a kind C development tool of specialized aim at 51 , it provided abundant database function, having the very strong data processing ability, when editing the distributing to the register and store of 8051 is automatically managed, as a result, usually the Cx51 writes the main procedure. However, sometimes also need to transfer A51 in the C programmer. In the past using assembly language write the subprogram, special function that need upper managing speed but must be write by simpler assembly language, or some interface programmer that require strictly but have to use more flexible assembly language etc. On the other hand, during the procedure that assembly language qua the main body, if involve the complicated mathematics operation, this will need transfer the function of C in the compile. This text based on the actual need, designed the menu screen's management method. Usually, the all or parts of the menu data are usually write straightly in main procedure, leading the programmer to be complex, and is hard to carry on the maintenance of many class menus and expand. In this text, introductive menu management project will separate menu programmer with main procedure, and contact each other with the point needle, even if more many class menus can modify or expand expediently. The work summary that this text makes is as follows: 1.Learn and study integration manufacturing, Flexible manufacturing, agile manufacturing etc. 2.Put forward for the very first time in keeping with medium, small enterprise manufacturing mode—Pseudo-enterprise regrouping produce mode. 3. Concretely research and put forward Pseudo-enterprise regrouping's produce mode, system structure and the management project . 4.According to the pseudo-enterprise regrouping's environment, design a kind of controller for raising the degree of integration behind the enterprise's regrouping. Namely Multifunctional machine tool assistant controller, carry through soft, the...
