CNC engraving machine change in the way of data transmission

Net friend ask: U disk technology can substitute for CNC engraving machine PC real-time data transmission? Yifan, nc: with the widely application of the numerical control technology and USB device of popularity. For CNC engraving machine on the accuracy is higher and higher, more and more small volume requirements, single chip microcomputer and USB device has become the inevitable trend of communication. But in nc engraving machine system data transmission must carry on the real-time data transmission with PC, so in this paper, the existing way of data transmission is improved, the usb technology to replace the original PC real-time data transmission, and the improvement to the original control system don't need to large-scale renovation, need only on the basis of the original design can increase the design system.
