| Wedm is widely developed earlier in our country, the application of special machining nc machine tool, at present there are hundreds of thousands of sets of high speed wire edm wedm is mould manufacturing and processing plays an important role, but the machine due to the early development of s, despite the accuracy stable mechanical system can meet the needs of actual production, but the control system and human-computer interaction function has lagged far behind the development of the computer progress, thus affecting the application of this kind of machine tools and production efficiency. Paper wedm CTW - 320 as an example, from three aspects of software, communication and circuit system design of the machine tool upgrading scheme.Using the Windows operating system has the characteristics of open architecture, the original DOS operating system upgrade in Windows98 operating system, hardware and software of the control system design and development, to be able to install CAXA software and other Chinese drawing CAD/CAM automatic programming software; Compatibility extends to the control system of data, make it can not only compatible with ISO code, 3 b code, such as the cutting programming code, and can make use of external CAD system to produce the DXF, DWG format graphics file programming; For reducing the occurrence of a tracking and owe phenomenon, improve the tracking precision of control system, through the original high frequency circuit triode series with BG’s emitter in the benchmark voltage source, add reference voltage source bias way to variable frequency voltage circuit of high frequency circuit part, improved the circuit the whole.Through technical renovation work, greatly promoted the openness, compatibility and stability of the machine to work, to ensure product quality and machining precision, reduces the loss of high frequency processing wire at the same time, improve the efficiency of wedm extra bed. |
