| Machine is mechanical processing core tool, called industrial tools. Our country use machine widely in the world. With the development of science and technology, machine tool technology also produced by the manual machine technological upgrading, and upgrading for numerical control machine. First, it bring enterprise funds huge pressure, most enterprise cannot bear this pressure; Secondly, comprehensive renewal request technical personnel's renewal, do not accord with China's national conditions;education can't keep up with the enterprise needs. So the old machine of numerical control reform has become the need. To improve industrial processing level of need, it become our country to promote knowledge property, also become the education. The." 1025 planning" added to focus on developing direction of industrialization and information fusion to realize the transformation of the fusion.According to the old machine tools need, in view of the combination of industry CA6140 ordinary lathe project to the numerical control transformation target, using the method of MCU application technology, automatic control technology and testing sensor technology, proposes the overall reconstruction scheme. Based on the design of MCS-51 single-chip microcomputer control edition; By simulation, the hardware and software to design is verified. This project explore an alteration of the old machine approach, method and technology of the same category, old machine reconstruction has reference.This article proposes the basic function principle of CA6140 lathe, the feasibility of numerical control transformation based on MCS-51 series microcontroller of CNC control edition design, information collection and driver interface circuit design, machine parts, electrical control circuit design comparative detailed analysis and describes the principle of machine tools, The methods and techniques for old machine tools has modification reference. |
